Houston has two Chinatowns, as well as the third largest Vietnamese American population in the United States. Recent redevelopment of Midtown from run-down to upscale has increased property values and property taxes, but has also forced some Vietnamese-Americans into other areas of the city. The older downtown Chinatown is also disappearing.
About 90 languages are frequently spoken in the Houston area. Some neighbourhoods with high populations of Vietnamese and Chinese residents have Chinese and Vietnamese street signs in addition to English ones. Houston has the second highest South African population in the United States, after Miami, Florida. The city is also noted for its large Nigerian population, counting about 100,000 native Nigerians as residents.
