Having recently expanded to include the municipalities of North York, Scarborough, Etobicoke, York, and East York, Metropolitan Toronto now has a population of some 4.2 million people, while the central city has over half a million. Known for its ethnic diversity, Toronto's population includes more than 80 different ethnic groups; about 100 different languages are spoken in the city. In the course of its history, Toronto has absorbed 350,000 Chinese immigrants, 400,000 Italians, 127,000 Greeks, and significant numbers of West Indians, Latin Americans, Indians, Sri Lankans, and Koreans. Nearly two-thirds of those who reside in Greater Toronto were born and raised elsewhere. The metropolitan area population includes the most extensive Portuguese population in North America, the largest Chinese population in eastern Canada, a half million Italians, and many other groups.
