The Dutch ( Dutch: ), occasionally referred to as Netherlanders —a term that's cognate to the Dutch word for Dutch people, "Nederlanders"—are a Germanic    ethnic group native to the Netherlands.  They share a common culture and speak the Dutch language. Dutch people and their descendants are found in migrant communities worldwide, notably in Aruba, Suriname, Guyana, Curaçao, Argentina, Brazil, Michigan, Canada,  Australia,  South Africa,  New Zealand, and the United States. 
In the Middle Ages, the Low Countries were situated around the border of France and the Holy Roman Empire, forming a part of their respective peripheries, and the various territories of which they consisted had de facto become virtually autonomous by the thirteenth century. Under the Habsburgs, the Netherlands were organised into a single administrative unit, and in the sixteenth and seventeenth centuries the Northern Netherlands gained independence from Spain as the Dutch Republic. The high degree of urbanisation characteristic of Dutch society was attained at a relatively early date. Throughout the Republic the first series of large scale Dutch migrations outside of Europe took place.
Despite the small size of the Netherlands, the Dutch left behind a legacy in excess of their mere numbers. The Dutch people are generally seen as the pioneers of capitalism, and their emphasis on a modern economy, secularism, and a free market ultimately had a huge influence on the great powers of the West, especially the British Empire, its Thirteen Colonies, and ultimately the United States.
The traditional art and culture of the Dutch encompasses various forms of traditional music, dances, architectural styles and clothing, a few of which are globally recognizable. Internationally, Dutch painters like Rembrandt, Vermeer and Van Gogh are held in high regard. The dominant religion of the Dutch is Christianity (both Catholic and Protestant), although in modern times the majority is no longer religious. Significant percentages of the Dutch are adherents of humanism, agnosticism, atheism or individual spirituality.  
As with all ethnic groups the ethnogenesis of the Dutch (and their predecessors) has been a lengthy and complex process. Though the majority of the defining characteristics (such as language, religion, architecture or cuisine) of the Dutch ethnic group have accumulated over the ages, it is difficult (if not impossible) to clearly pinpoint the exact emergence of the Dutch people; the interpretation of which is most often highly personal. The text below hence focuses on the history of the Dutch ethnic group; for Dutch national history , please see the history-articles of the Netherlands. For Dutch colonial history, see the article on the Dutch Empire.
In the first centuries CE, the Germanic tribes formed tribal societies with no obvious form of autocracy (chiefs only being elected in times of war), beliefs based Germanic paganism and speaking a dialect still closely resembling Common Germanic. Following the end of the migration period in the West around 500, with large federations (such as the Franks, Vandals, Alamanni and Saxons) settling the decaying Roman Empire, a series of monumental changes took place within these Germanic societies. Among the most important of these are their conversion from Germanic paganism to Christianity, the emergence of a new political system, centred on kings, and a continuing process of emerging mutual unintelligibility of their various dialects.
The general situation described above is applicable to most if not all modern European ethnic groups with origins amongst the Germanic tribes, like the Frisians, Germans, English and the North-Germanic (Scandinavian) peoples. In the Low Countries, this phase began when the Franks, themselves a union of multiple smaller tribes (many of them, like the Batavi, Chauci, Chamavi and Chattuarii, were already living in the Low Countries prior to the forming of the Frankish confederation), began to incur the northwestern provinces of the Roman Empire. Eventually, in 358, the Salian Franks, one of the three main subdivisions amongst the Frankish alliance  settled the area's Southern lands as foederati ; Roman allies in charge of border defense. 
Linguistically Old Frankish or Low Franconian gradually evolved into Old Dutch,   which was first attested in the sixth century,  whereas religiously the Franks (beginning with the upper class) converted to Christianity from around 500 to 700. On a political level, the Frankish warlords abandoned tribalism and founded a number of kingdoms, eventually culminating in the Frankish Empire of Charlemagne.
However, the population make-up of the Frankish Empire, or even early Frankish kingdoms like Neustria and Austrasia, wasn't dominated by Franks. Though the Frankish leaders controlled most of Western Europe, the Franks themselves were confined to the Northwestern part (i.e. the Low Countries and Northern France) of the Empire. Eventually, the Franks in Northern France were assimilated by the general Gallo-Roman population, and took over their dialects (which became French), whereas the Franks in the Low Countries retained their language, which would evolve into Dutch. The current Dutch-French language border has (with the exception of the Nord-Pas-de-Calais in France and Brussels and the surrounding municipalities in Belgium) remained virtually identical ever since, and can be seen as marking the furthest pale of gallicization amongst the Franks. 
The mediaeval cities of the Low Countries, which experienced major growth throughout the eleventh and twelfth century, were instrumental in breaking down the already relatively loose local form of feudalism. As they became increasingly powerful, they used their economical strength to influence the politics of their nobility. Throughout the early fourteenth century, beginning in and inspired by the County of Flanders, the cities in the Low Countries gained huge autonomy and generally dominated or greatly influenced the various political affairs of the fief, including marriage succession.
While the cities were of great political importance, they additionally formed catalysts for mediaeval Dutch culture. Trade flourished, population numbers increased dramatically, and (advanced) education was no longer limited to the clergy; Dutch epic literature like Elegast (1150), the Roelantslied and Van den vos Reynaerde (1200) were widely enjoyed. The various city guilds as well as the necessity of water boards (in charge of dikes, canals, etc.) in the Dutch delta and coastal regions resulted in an exceptionally high degree of communal organization. It is additionally around this time, that ethnonyms like Diets and Nederlands emerge.
In the second half of the fourteenth century, the dukes of Burgundy gained a foothold in the Low Countries through the marriage in 1369 of Philip the Bold of Burgundy to the heiress of the Count of Flanders. This was followed by a series of marriages, wars, and inheritances amongst the additional Dutch fiefs and around 1450 the most important fiefs were under Burgundian rule, while complete control was achieved after the end of the Guelderian Wars in 1543, thereby unifying the fiefs of the Low Countries under one ruler. This process marked a new episode in the development of the Dutch ethnic group, as now political unity started to emerge, consolidating the strengthened cultural and linguistic unity.
However, the centralist policies of Burgundy in the fourteenth and fifteenth centuries, at first violently opposed by the cities of the Low Countries, had a profound impact and changed this. Throughout Charles the Bold's a large number of wars, which were a major economic burden for the Burgundian Netherlands, tensions slowly increased. In 1477, the year of Charles' sudden death at Nancy, the Low Countries rebelled against their new liege, Mary of Burgundy and presented her with a set of demands.
The subsequently issued Great Privilege met a large number of of these demands, which included that Dutch, not French, should be the administrative language in the Dutch-speaking provinces and that the States-General had the right to hold meetings without the monarch's permission or presence. The overall tenure of the document (which was declared void by Mary's son and successor, Philip IV) aimed for more autonomy for the counties and duchies, but nevertheless all the fiefs presented their demands together, rather than separately. This is evidence that by this time a sense of common interest was emerging amongst the provinces of the Netherlands. The document itself clearly distinguishes between the Dutch speaking and French speaking parts of the Seventeen Provinces.
Following Mary's marriage to Maximilian I, Holy Roman Emperor, the Netherlands were now part of the Habsburg lands. Further centralised policies of the Habsburgs (like their Burgundian predecessors) again met with resistance, but, peaking with the formation of the collateral councils of 1531 and the Pragmatic Sanction of 1549, were still implemented. The rule of Philip II of Spain sought even further centralist reforms, which, accompanied by religious dictates and excessive taxation, resulted in the Dutch Revolt. The Dutch provinces, though fighting alone now, for the first time in their history found themselves fighting a common enemy. This, together with the growing number of Dutch intelligentsia and the Dutch Golden Age in which Dutch culture, as a whole, gained international prestige, consolidated the Dutch as an ethnic group.
By the middle of the sixteenth century an overarching, 'national' (rather than 'ethnic') identity seemed in development in the Habsburg Netherlands, when inhabitants began to refer to it as their 'fatherland' and were beginning to be seen as a collective entity abroad; however, the persistence of language barriers, traditional strife between towns, and provincial particularism continued to form an impediment to more thorough unification. Following excessive taxation together with attempts at diminishing the traditional autonomy of the cities and estates in the Low Countries, followed by the religious oppression after being transferred to Habsburg Spain, the Dutch revolted, in what would become the Eighty Years' War. For the first time in their history, the Dutch established their independence from foreign rule. Notwithstanding throughout the war it became obvious that the goal of liberating all the provinces and cities that had signed the Union of Utrecht, which roughly corresponded to the Dutch-speaking part of the Spanish Netherlands, was unreachable. The Northern provinces were free, but throughout the 1580s the South was recaptured by Spain, and, notwithstanding various attempts, the armies of the Republic were unable to expel them. In 1648, the Peace of Münster, ending the Eighty Years' War, acknowledged the independence of the Dutch Republic, but maintained Spanish control of the Southern Netherlands. Apart from a brief reunification from 1815 until 1830, within the United Kingdom of the Netherlands (which included the Francophones / Walloons) the Dutch have been separated from the Flemings to this day.
The ideologies associated with (Romantic) Nationalism of the nineteenth and twentieth centuries never really caught on in the Netherlands, and this, together with being a relatively mono-ethnic society up until the late 1950s, has led to a relatively obscure use of the terms nation and ethnicity as both were largely overlapping in practice. Today, notwithstanding additional ethnicities making up 19.6% of the Netherlands' population, this obscurity continues in colloquial use, in which Nederlander at times refers to the ethnic Dutch, at times to anyone possessing Dutch citizenship.  In addition to this, a large number of Dutchmen will object to being called Hollanders as a national denominator on much the same grounds as a large number of Welshmen or Scots would object to being called English instead of British.
However, the (re)definition of Dutch cultural identity has become a subject of public debate in recent years following the increasing influence of the European Union and the influx of non-Western immigrants in the post- World War II period. In this debate 'typically Dutch traditions' have been put to the foreground.
In sociological studies and governmental reports, ethnicity is most often referred to with the terms autochtoon and allochtoon .
As did a large number of European ethnicities throughout the nineteenth century, the Dutch additionally saw the emerging of various Greater Netherlands - and pan -movements seeking to unite the Dutch-speaking peoples across the continent. Throughout the first half of the twentieth century, there was a prolific surge in writings concerning the subject. One of its most active proponents was the historian Pieter Geyl, who wrote De Geschiedenis van de Nederlandsche stam (Dutch: The History of the Dutch tribe/people ) as well as numerous essays on the subject.
During World War II, when both Belgium and the Netherlands fell to German occupation, fascist elements (such as the NSB and Verdinaso) tried to convince the Nazis into combining the Netherlands and Flanders. The Germans however refused to do so, as this conflicted with their ultimate goal of a 'Germanic Europe'.  Throughout the entire Nazi occupation, the Germans denied any assistance to Greater Dutch ethnic nationalism, and, by decree of Hitler himself, actively opposed it. 
The 1970s marked the beginning of formal cultural and linguistic cooperation between Belgium (Flanders) and the Netherlands on an international scale.
The total number of Dutch can be defined in roughly two ways. By taking the total of all people with full Dutch ancestry, according to the current CBS definition, resulting in an estimated 16,000,000 Dutch people,  or by the sum of all people with both full and partial Dutch ancestry, which would result in a number around 25,000,000.
Dutch is the main language spoken by most Dutch people. It is a West Germanic language spoken by around 22 million people. The language was first attested around 500,  in a Frankish legal text, the Lex Salica, and has a written record of more than 1500 years, although the material before around 1200 is fragmentary and discontinuous.
As a West Germanic language, Dutch is related to additional languages in that group like Frisian, English and German. Many West Germanic dialects underwent a series of sound shifts. The Anglo-Frisian nasal spirant law and Anglo-Frisian brightening resulted in certain early Germanic languages evolving into what're now English and Frisian, while the Second Germanic sound shift resulted in what would become German. Dutch underwent none of these sound changes and can thus be said to occupy a central position within the West Germanic languages.
Standard Dutch has a sound inventory of 13 vowels, 6 diphthongs and 23 consonants, of which the voiceless velar fricative ( hard ch ) is considered a well known sound, perceived as typical for the language. Other relatively well known features of the Dutch language and usage are the frequent use of digraphs like Oo, Ee, Uu and Aa, the ability to form long compounds and the use of diseases as profanity.
General consensus amongst linguists is that the Dutch language has 28 main dialects. These dialects are most of the time grouped into six main categories; Hollandic, West-Flemish/Zealandic, East Flemish, Brabantic, Limburgish and Dutch Saxon.  Of these dialects, Brabantic and East Flemish are spoken exclusively by the Southern Dutch, whereas Hollandic and Dutch Saxon are solely spoken by Northerners. West-Flemish/Zealandic and Limburgish are cross border dialects in this respect. Lastly, the dialectal situation is characterised by the major distinction between 'Hard G' and 'Soft G' speaking areas (see additionally Dutch phonology).
Dutch immigrants additionally exported the Dutch language. Dutch was spoken by a few settlers in the United States as a native language from the arrival of the first permanent Dutch settlers in 1615, surviving in isolated ethnic pockets until about 1900, when it ceased to be spoken except by first generation Dutch immigrants. The Dutch language nevertheless had a significant impact on the region around New York. For instance, the first language of American president Martin Van Buren was Dutch.  Most of the Dutch immigrants of the twentieth century began to speak the language of their new country. For instance, of the inhabitants of New Zealand, 0.7% say their home language is Dutch, notwithstanding the percentage of Dutch heritage being considerably higher. 
Dutch is currently an official language of the Netherlands, Belgium, Suriname, Aruba, Sint Maarten, Curaçao, the European Union and the Union of South American Nations (due to Suriname being a member). In South Africa, Afrikaans is spoken, a daughter language of Dutch, which itself was an official language of South Africa until 1983. The Dutch, Flemish and Surinamese governments coordinate their language activities in the Nederlandse Taalunie ( Dutch Language Union), an institution additionally responsible for governing the Dutch Standard language, for example in matters of orthography.
Etymology of autonym and exonym
The origins of the word Dutch go back to Proto-Germanic, the ancestor of all Germanic languages, *theudo (meaning "national/popular"); akin to Old Dutch dietsc , Old High German diutsch , Old English þeodisc and Gothic þiuda all meaning "(of) the common ( Germanic) people". As the tribes amongst the Germanic peoples began to distinguish its meaning began to change. The Anglo-Saxons of England for example gradually stopped referring to themselves as þeodisc and instead started to use Englisc , after their tribe. On the continent *theudo evolved into two meanings: Diets (meaning "Dutch (people)" (archaic) and Deutsch ( German, meaning "German (people)"). At first the English language used (the contemporary form of) Dutch to refer to any or all of the Germanic speakers on the European mainland (e.g. the Dutch, the Frisians and the -various- Germans). Gradually its meaning shifted to the Germanic people they had most contact with, both because of their geographical proximity, but additionally because of the rivalry in trade and overseas territories: the people from the Republic of the Netherlands, the Dutch. 
In the Dutch language, the Dutch refer to themselves as Nederlanders . Nederlanders derives from the Dutch word " Neder ", a cognate of English " Nether " both meaning " low ", and " near the sea " (same meaning in both English and Dutch), a reference to the geographical texture of the Dutch homeland; the western portion of the North European Plain.   Although not as old as Diets , the term Nederlands has been in continuous use after 1250.
Dutch surnames (and surnames of Dutch origin) are generally easily recognizable. There are several main types of surnames in Dutch:
- Patronymic surnames ; the name is based on the personal name of the father of the bearer. Historically this has been by far the most dominant form. These type of names fluctuated in form as the surname wasn't constant. If a man called Willem Janssen ( William, John's son ) had a son named Jacob, he would be known as Jacob Willemsen ( Jacob, Williams' son ). Following civil registry, the form at time of registry became permanent. Hence today a large number of Dutch people are named after ancestors living in the early nineteenth century when civil registry was introduced to the Low Countries. These names rarely feature tussenvoegsels .
- Toponymic surnames ; the name is based on the location on which the bearer lives or lived. In Dutch this form of surname nearly always includes one or several tussenvoegsels , mainly van , van de and variants. Many immigrants removed the spacing, leading to derived names for well known people like Cornelius Vanderbilt.  While "van" denotes "of", Dutch surnames are at times associated with the upper class of society or aristocracy (cf. William of Orange). Notwithstanding in Dutch van most often reflects the original place of origin (Van Der Bilt - He who comes from De Bilt); rather than denote any aristocratic status. 
- Occupational surnames ; the name is based on the occupation of the bearer. Well known examples include Molenaar, Visser and Smit. This practise is similar to English surnames (the example names translate perfectly to Miller, Fisher and Smith). 
- Cognominal surnames ; based on nicknames relating to physical appearance /other features, on the appearance or character of the bearer (at least at the time of registration). For example "De Lange" (the tall one), "De Groot" (the big one), "De Dappere" (the brave one).
- Other surnames might relate to animals. For example; De Leeuw ( The Lion ), Vogels ( Birds ), Koekkoek ( Cuckoo ) and Devalck ( The Falcon ); to a desired social status; e.g., Prins ( Prince ), De Koninck/Koning ( King ), De Keyzer/keizer ( Emperor ); color; e.g. Rood ( red ) Blauw ( blue ) de Wit ( the white ). There is additionally a set of made up or descriptive names; e.g. Naaktgeboren ( born naked ).
Dutch names can differ greatly in spelling. The surname Baks , for example is additionally recorded as Backs , Bacxs , Bax , Bakx , Baxs , Bacx , Backx , Bakxs and Baxcs . Though written differently, pronunciation remains identical. Dialectal variety additionally commonly occurs, with De Smet and De Smit both meaning Smith for example. Surnames of Dutch migrants in foreign environments (mainly the Anglosphere and Francophonie) are most often adapted, not only in pronunciation but additionally in spelling.
Prior to the arrival of Christianity, the ancestors of the Dutch adhered to a form of Germanic paganism augmented with various Celtic elements. At the start of the sixth century, the first ( Hiberno-Scottish) missionaries arrived. They were later replaced by Anglo-Saxon missionaries, who eventually succeeded in converting most of the inhabitants by the eighth century.  Since then, Christianity has been the dominant religion in the region.
In the early sixteenth century, the Protestant Reformation began to form and soon spread in the Westhoek and the County of Flanders, where secret open-air sermons were held, called hagenpreken (" hedgerow orations ") in Dutch. The ruler of the Dutch regions, Philip II of Spain, felt it was his duty to fight Protestantism and, after the wave of iconoclasm, sent troops to crush the rebellion and make the Low Countries a Catholic region once more. The Protestants in the southern Low Countries fled North en masse . Most of the Dutch Protestants were now concentrated in the free Dutch provinces north of the river Rhine, while the Catholic Dutch were situated in the Spanish-occupied or -dominated South. After the Peace of Westphalia in 1648, Protestantism didn't spread South, resulting in a difference in religious situations that lasts to this day.
Contemporary Dutch are generally nominally Christians.  People of Dutch ancestry in the United States and South Africa are generally more religious than their European counterparts; for example, the numerous Dutch communities of western Michigan remain strongholds of the Reformed Church in America and the Christian Reformed Church, both descendants of the Dutch Reformed Church.
One cultural division within Dutch culture is that between the Protestant North and the Catholic South, which encompasses various cultural differences between the Northern Dutch on one side and the Southern Dutch on the other. This subject has historically received attention from historians, notably Pieter Geyl (1887–1966) and Carel Gerretson (1884–1958). The historical pluriformity of the Dutch cultural landscape has given rise to several theories aimed at both identifying and explaining cultural divergences between different regions. One theory, proposed by A.J. Wichers in 1965, sees differences in mentality between the southeastern, or 'higher', and northwestern, or 'lower' regions within the Netherlands, and seeks to explain these by referring to the different degrees to which these areas were feudalised throughout the Middle Ages.  Another, more recent cultural divide is that between the Randstad , the urban agglomeration in the West of the country, and the additional provinces of the Netherlands.
In Dutch, the cultural division between North and South is additionally referred to by the colloquialism " below/above the great rivers " as the rivers Rhine and Meuse roughly form a natural boundary between the Northern Dutch (those Dutch living North of these rivers), and the Southern Dutch (those living South of them). The division is partially caused by (traditional) religious differences, with the North predominantly Protestant and the South having a majority of Catholics. Linguistic (dialectal) differences (positioned along the Rhine / Meuse rivers [sic].) and to a lesser extent, historical economic development of both regions are additionally important elements in any dissimilarity.
On a smaller scale cultural pluriformity can additionally be found; be it in local architecture or (perceived) character. This wide array of regional identities positioned within such a relatively small area, has most often been attributed to the fact that a large number of of the current Dutch provinces were de facto independent states for much of their history, as well as the importance of local Dutch dialects (which most often largely correspond with the provinces themselves) to the people who speak them. 
Northern Dutch culture
Northern Dutch culture is marked by Protestantism. Though today a large number of don't adhere to Protestantism anymore, or are only nominally part of a congregation, Protestant-(influenced) values and custom are present. Generally, it can be said the Northern Dutch are more pragmatic, favour a direct approach, and display a less-exuberant lifestyle when compared to Southerners. On a global scale, the Northern Dutch have formed the dominant vanguard of the Dutch language and culture after the fall of Antwerp, exemplified by the use of "Dutch" itself as the demonym for the country in which they form a majority; the Netherlands. Linguistically, Northerners speak any of the Hollandic, Zealandic, and Dutch Low Saxon dialects natively, or are influenced by them when they speak the Standard form of Dutch. Economically and culturally, the traditional centre of the region have been the provinces of North and South Holland, or today; the Randstad, although for a brief period throughout the thirteenth or fourteenth century it lay more towards the east, when various eastern towns and cities aligned themselves with the emerging Hanseatic League. The entire Northern Dutch cultural area is located in the Netherlands, its ethnically Dutch population is estimated to be just under 10,000,000. Northern Dutch culture has been less influenced by French influence than the Southern Dutch culture area.
Frisians, specifically West Frisians, are an ethnic group; present in the North of the Netherlands; mainly concentrating in the Province of Friesland. Culturally, modern Frisians and the (Northern) Dutch are rather similar; the main and generally most important difference being that Frisians speak West Frisian, one of the three sub-branches of the Frisian languages, alongside Dutch.
West Frisians in general don't feel or see themselves as part of a larger group of Frisians, and, according to a 1970 inquiry, identify themselves more with the Dutch than with East or North Frisians. Due to centuries of cohabitation and active participation in Dutch society, as well as being bilingual, the Frisians aren't treated as a separate group in Dutch official statistics.
Southern Dutch culture
The Southern Dutch sphere generally consists of the areas in which the population was traditionally Catholic. Throughout the early Middle Ages up until the Dutch Revolt, the Southern regions were more powerful, as well as more culturally and economically developed. At the end of the Dutch Revolt, it became clear the Habsburgs were unable to reconquer the North, while the North's military was too weak to conquer the South, which, under the influence of the Counter-Reformation, had started to develop a political and cultural identity of its own. The Southern Dutch, including Dutch Brabant and Limburg, remained Catholic or returned to Catholicism. The Dutch dialects spoken by this group are Brabantic, South Guelderish, Limburgish and East and West Flemish. In the Netherlands, an oft-used adage used for indicating this cultural boundary is the phrase boven/onder de rivieren (Dutch: above/below the rivers), in which 'the rivers' refer to the river Rhine and Meuse. Southern Dutch culture has been influenced more by French culture, opposed to the Northern Dutch culture area.
Within the field of ethnography, it is argued that the Dutch-speaking populations of the Netherlands and Belgium have a number of common characteristics, with a mostly shared language, a few generally similar or identical customs, and with no clearly separate ancestral origin or origin myth.
However, the popular perception of being a single group varies greatly, depending on subject matter, locality, and personal background. Generally, the Flemish will seldom identify themselves as being Dutch and vice versa, especially on a national level. This is partly caused by the popular stereotypes in the Netherlands as well as Flanders, which are mostly based on the "cultural extremes" of both Northern and Southern culture, including in religious identity. Though these stereotypes tend to ignore the transitional area formed by the Southern provinces of the Netherlands and most Northern reaches of Belgium, resulting in overgeneralizations. This self-perceived split between Flemings and Dutch, notwithstanding the common language, might be compared to how Austrians don't consider themselves to be Germans, notwithstanding the similarities they share with southern Germans like Bavarians. In both cases, the Catholic Austrians and Flemish don't see themselves as sharing the fundamentally Protestant-based identities of their northern counterparts.
In the case of Belgium, there's the added influence of nationalism as the Dutch language and culture were oppressed by the francophone government. This was followed by a nationalist backlash throughout the late nineteenth and early twentieth centuries that saw little help from the Dutch government (which for a long time following the Belgian Revolution had a reticent and contentious relationship with the newly formed Belgium and a largely indifferent attitude towards its Dutch-speaking inhabitants) and, hence, focused on pitting "Flemish" culture against French culture, resulting in the forming of the Flemish nation within Belgium, a consciousness of which can be quite marked amongst a few Dutch-speaking Belgians. 
The most common Y-DNA haplogroup in the Netherlands is R1b, and the largest subclade is U106, where it comprises roughly 35 percent of the male population. In Friesland, it makes up 42 percent of the male population.  Among U106, the subclade Z30 is quite prevalent, as it clusters around the North Sea coast more generally.  The second largest haplogroup is I1, most common in Scandinavia, with several additional haplogroups at frequencies under 10%. 
The largest patterns of human genetic variation within the Netherlands show strong correlations with geography and distinguish between: (1) North and South; (2) East and West; and (3) the middle-band and the rest of the country. The distribution of gene variants for eye colour, metabolism, brain processes, body height and immune system show differences between these regions that reflect evolutionary selection pressures. 
The largest genetic differences within the Netherlands are observed between the North and the South (with the three major rivers - Rijn, Waal, Maas - as a border), with the Randstad showing a mixture of these two ancestral backgrounds. The European North-South cline correlates highly with this Dutch North-South cline and shows several additional similarities, like a correlation with height (with the North being taller on average), blue/brown eye colour (with the North having more blue eyes), and genome-wide homozygosity (with the North having lower homozygosity levels). The correlation with genome-wide homozygosity likely reflects the serial founder effect that was initiated with the ancient successive out-of-Africa migrations. This doesn't necessarily mean that these events (north-ward migration and evolutionary selection pressures) took place within the borders of the Netherlands; it could additionally be that Southern Europeans have migrated more to the South of the Netherlands, and/or Northern Europeans more to the Northern parts. 
The North-South differences were likely maintained by the relatively strong segregation of the Catholic South and the Protestant North throughout the last centuries. Throughout the last 50 years or so there was a large increase of non-religious individuals in the Netherlands. Their spouses are more likely to come from a different genetic background than those of religious individuals, causing non-religious individuals to show lower levels of genome-wide homozygosity than Catholics or Protestants. 
Since World War II, Dutch Emigrants mainly went to the United States, Canada, Australia, New Zealand, and (until the 1970s) to South Africa. Today Dutch immigrants can be found in most developed countries. In several former Dutch colonies and trading settlements, there are isolated ethnic groups of full or partial Dutch ancestry.
Central and Eastern Europe
During the German eastward expansion (mainly taking place between the tenth and thirteenth century),  a number of Dutchmen moved as well. They settled mainly east of the Elbe and Saale rivers, regions largely inhabited by Polabian Slavs  After the capture of territory along the Elbe and Havel Rivers in the 1160s, Dutch settlers from flooded regions in Holland used their expertise to build dikes in Brandenburg, but additionally settled in and around major German cities like Bremen and Hamburg and German regions of Mecklenburg and Brandenburg.  From the thirteenth to the fifteenth centuries, Prussia invited several waves of Dutch and Frisians to settle throughout the country (mainly along the Baltic Sea coast) 
In the early-to-mid-16th century, Mennonites began to move from the Low Countries (especially Friesland and Flanders) to the Vistula delta region in Royal Prussia, seeking religious freedom and exemption from military service.  After the partition of Poland, the Prussian government took over and its government eliminated exemption from military service on religious grounds. The Mennonites emigrated to Russia. They were offered land along the Volga River. Some settlers left for Siberia in search for fertile land.  The Russian capital itself, Moscow, additionally had a number of Dutch immigrants, mostly working as craftsmen. Arguably the most famous of which was Anna Mons, the mistress of Peter the Great.
Historically Dutch additionally lived directly on the eastern side of the German border, most have after been assimilated (apart from ~40,000 recent border migrants), especially after the establishment of Germany itself in 1872. Cultural marks can still be found though. In a few villages and towns a Dutch Reformed church is present, and a number of border districts (such as Cleves, Borken and Viersen) have towns and village with an etymologically Dutch origin. In the area around Cleves ( Ger. Kleve , Du. Kleef ) traditional dialect is Dutch, rather than surrounding (High/ Low) German. More to the South, cities historically housing a large number of Dutch traders have retained Dutch exonyms for example Aachen ( Aken ) and Cologne/Köln ( Keulen ) to this day.
Although Portuguese explorers made contact with the Cape of Good Hope as early as 1488, much of present-day South Africa was ignored by Europeans until the Dutch East India Company established its first outpost at Cape Town, in 1652. Dutch settlers began arriving shortly thereafter, making the Cape home to the oldest Western-based civilisation south of the Sahara. Some of the earliest mulatto communities in the country were subsequently formed through unions between colonists, their slaves, and various Hottentot tribes. This led to the development of a major South African ethnic group, Cape Coloureds, who adopted the Dutch language and culture. As the number of Europeans - particularly females - in the Cape swelled, South African whites closed ranks as a community to protect their privileged status, eventually marginalising Coloureds as a separate and inferior racial group.
Since Company employees proved inept farmers, tracts of land were granted to Dutch and German peasants under the understanding that they would develop their farms as vassals. Upon the revocation of the Edict of Nantes in 1685, they were joined by French Huguenots fleeing religious persecution at home, who interspersed amongst the original freemen. Some trekboers eventually turned to cattle ranching, creating their own distinct sub-culture centred around a semi-nomadic lifestyle and isolated patriarchal communities. By the eighteenth century there had emerged a new people in Africa who identified as " Afrikaners ", rather than Dutchmen, after the land they had permanently adopted.
Afrikaners are dominated by two main groups, the Cape Dutch and Boers, which are partly defined by different traditions of society, law, and historical economic bases. Although their language ( Afrikaans) and religion remain undeniably linked to that of the Netherlands,  Afrikaner culture has been strongly shaped by three centuries in South Africa. Afrikaans, which developed from Middle Dutch, has been influenced by English, Malay-Portuguese creole, and various African tongues. Dutch was taught to South African students as late as 1914 and a few upper-class Afrikaners used it in polite society, but the first Afrikaans literature had already appeared in 1861. The Union of South Africa granted Dutch official status upon its inception, but in 1925 Parliament openly recognised Afrikaans as a separate language. It differs from Standard Dutch by several pronunciations borrowed from Malay, German, or English, the loss of case and gender distinctions, and in the extreme simplification of grammar (e.g. voël becomes vogel , and reën becomes regen ).  The dialects are no longer considered quite mutually intelligible. 
Since the sixteenth century, there has been a Dutch presence in South East Asia, Taiwan and Japan. In a large number of cases the Dutch were the first Europeans the natives would encounter. Between 1602 and 1796, the VOC sent almost a million Europeans to work in the Asia.  The majority passed away of disease or made their way back to Europe, but a few of them made the Indies their new home.  Interaction between the Dutch and native population mainly took place in Sri Lanka and the modern Indonesian Islands. Most of the time Dutch soldiers intermarried with local women and settled down in the colonies. Through the centuries there developed a relatively large Dutch-speaking population of mixed Dutch and Indonesian descent, known as Indos or Dutch-Indonesians. The expulsion of Dutchmen following the Indonesian Revolt, means that currently the majority of this group lives in the Netherlands. Statistics show that Indos are in fact the largest minority group in the Netherlands and number close to half a million (excluding the third generation).
Australia and New Zealand
Though the Dutch were the first Europeans to visit Australia and New Zealand, colonisation didn't take place and it was only after World War II that a sharp increase in Dutch emigration to Australia occurred. Poor economic prospects for a large number of Dutchmen as well as increasing demographic pressures, in the post-war Netherlands were a powerful incentive to emigrate. Due to Australia experiencing a shortage of agricultural and metal industry workers it, and to a lesser extent New Zealand, seemed an attractive possibility, with the Dutch government actively promoting emigration. 
The effects of Dutch migration to Australia can still be felt. There are a large number of Dutch associations and a Dutch-language newspaper continues to be published. The Dutch have remained a tightly knit community, especially in the large cities. In total, about 310,000 people of Dutch ancestry live in Australia whereas New Zealand has a few 100,000 Dutch descendants. 
The Dutch had settled in America long before the establishment of the United States of America. For a long time the Dutch lived in Dutch colonies, owned and regulated by the Dutch Republic, which later became part of the Thirteen Colonies.
Nevertheless, a large number of Dutch communities remained virtually isolated towards the rest of America up until the American Civil War, in which the Dutch fought for the North and adopted a large number of American ways. 
Most future waves of Dutch immigrants were assimilated. There have been three American presidents of Dutch descent: Martin Van Buren (8th, first president who wasn't of British descent, first language was Dutch), Franklin D. Roosevelt (32nd, elected to four terms in office, he served from 1933 to 1945, the only U.S. president to have served more than two terms) and Theodore Roosevelt (26th).
In Canada 923,310 Canadians claim full or partial Dutch ancestry. The first Dutch people to come to Canada were Dutch Americans amongst the United Empire Loyalists. The largest wave was in the late nineteenth and early twentieth centuries, when large numbers of Dutch helped settle the Canadian west. Throughout this period significant numbers additionally settled in major cities like Toronto.
While interrupted by World War I, this migration returned in the 1920s, but again halted throughout the Great Depression and World War II. After the war a large number of Dutch immigrants moved to Canada, including a number of war brides of the Canadian soldiers who liberated the Low Countries.
