Nairobi is a culturally diverse city. All the major Kenyan ethnic groups are represented in the city, and these include the Kikuyu, Luo, Luhyia, Kalenjin, Kisii, and Kamba. While it is difficult to know the exact percentages of the ethnic makeup of Nairobi, there are probably more Kikuyu living in the city than any other group. The Kikuyu make up around 20 percent of the Kenyan population, and their home area borders Nairobi. In addition to the Kenyan African ethnic groups, there is a sizeable population of Asians (people who trace their origins to India and Pakistan), Europeans, and Somalis. Nairobi is also home to a sizeable expatriate (people who have left their homeland) community as numerous embassies and international organizations have offices in the city.
