There is a sizable minority population of European origin, especially Portuguese (about 260,000), as well as Brazilians. In recent years, mainly since the mid-2000s, immigration from Portugal has increased due to greater opportunities present in Angola's booming economy. There is a sprinkling of immigrants from other African countries as well, including a small expatriate South African community. A small number of people of Luanda are of mixed race — European/Portuguese and native African. Over the last decades, a significant Chinese community has formed, as has a much smaller Vietnamese community.
