The Maasai (also called Masai) are an indigenous African ethnic group of semi-nomadic people located in Kenya and northern Tanzania. Due to their distinctive customs and dress and residence near the many game parks of East Africa, they are among the most well known of African ethnic groups. They speak Maa, a member of the Nilo-Saharan language family that is related to Dinka and Nuer, and are also educated in the official languages of Kenya and Tanzania: Swahili and English. The Maasai population has been variously estimated as 377,089 from the 1989 Census or as 453,000 language speakers in Kenya in 1994 and 430,000 in Tanzania in 1993 with a total estimated as "approaching 900,000". Estimates of the respective Maasai populations in both countries are complicated by the remote locations of many villages, and their semi-nomadic nature.
