Angola has three main ethnic groups, each speaking a Bantu language: Ovimbundu 37%, Kimbundu 25%, and Bakongo 13%. Other groups include Chokwe, Lunda, Ganguela, Nhaneca-Humbe, Ambo, Herero, and Xindunga. In addition, mixed racial (European and African) people amount to about 2%, with a small (1%) population of whites, mainly ethnically Portuguese. Portuguese make up the largest non-Angolan population, with at least 30,000 (though many native-born Angolans can claim Portuguese nationality under Portuguese law). Portuguese is both the official and predominant language.
