The great majority of inhabitants of the Netherlands are Dutch. They are mainly descended from Franks, Frisians, and Saxons. Most residents of Friesland Province are Frisian, a distinct cultural group with its own language. Fearing overpopulation, the government encouraged Dutch emigration after World War II (1939-1945), and some 500,000 people left. But an even larger number of people entered the Netherlands — Europeans and Asians from the former Netherlands Indies dependency (now part of Indonesia); industrial workers from Turkey, Morocco, and other Mediterranean countries; and, more recently, residents of Suriname, also a former Dutch dependency, and the Netherlands Antilles. Consequently, the country's population, particularly in the large cities, now includes several ethnic minorities.
