Kikuyu

Here's the wikipedia article on the Kikuyu people and their language. The article says that 22% of the people in Kenya are Kikuyu, and a lot of them speak the language. For some reason I was under the impression that English and Swahili were the 2 main languages in Kenya, but is seems like a good number of people speak Kikuyu.
