The Maasai are a Nilotic ethnic group of semi-nomadic people inhabiting southern Kenya and northern Tanzania. They are among the best known local populations due to their residence near the many game parks of the African Great Lakes, and their distinctive customs and dress. The Maasai speak Maa (ɔl Maa), a member of the Nilo-Saharan language family that is related to Dinka and Nuer. They are also educated in the official languages of Kenya and Tanzania, Swahili and English. The Maasai population has been reported as numbering 841,622 in Kenya in the 2009 census, compared to 377,089 in the 1989 census.
