http://countrystudies.us/portugal/55.htm > > Portugal's long colonial history, more than half a millennium, has left some traces of ethnic diversity. Former colonists were found mainly in Lisbon, particularly after the colonies were granted independence in the mid-1970s. Groups of Angolans, Mozambicans, S�o Tomans, Timorese, Goans, and Macaoans have settled in the capital city, and, along with Brazilian immigrants, amounted to perhaps 100,000 persons. The Goans came from the Indian subcontinent and were usually educated, Roman Catholic, and Portuguese speaking. They were better assimilated than most other groups. The Macaoans were generally of Chinese descent, and many had opened businesses. Another group from Asia, the Timorese, were not as well educated as the other eastern groups. A population of less than 100,000 black immigrants from Portugal's African colonies often lived together in small ghettos in Lisbon and did not generally assimilate. Many of these minorities used Portugal as a stoppingoff point en route to more prosperous countries in Western Europe, but as the Portuguese economy began to improve in the second half of the 1980s, more chose to stay permanently. These ethnic minorities from the former colonies were not fully assimilated and often faced to a varying degree racial and cultural prejudice. However, the small size of these diverse ethnic groups prevented this apartness from being a serious social problem. The only group from the former colonies that was fully assimilated, despite some cultural and adjustment problems, comprised those coming from the former colonies in Africa who were of Portuguese descent. They had much the same racial and cultural background as the Portuguese themselves. Some of them, like some of the Brazilians, did very well in their cultural homeland and even became wealthy.
