What are the three largest ethnic groups in Kenya?

### Input:
Kenya has a diverse population that includes many of Africa's major ethnoracial and linguistic groups. Although there is no official list of Kenyan ethnic groups, the number of ethnic categories and sub-categories recorded in the country's census has changed significantly over time, expanding from 42 in 1969 to more than 120 in 2019. Most residents are Bantus (60%) or Nilotes (30%). Cushitic groups also form a small ethnic minority, as do Arabs, Indians, and Europeans.

According to the Kenya National Bureau of Statistics (KNBS), in 2019, Kenya had a total population of 47,564,296. The largest native ethnic groups were the Kikuyu (8,148,668), Luhya (6,823,842), Kalenjin (6,358,113), Luo (5,066,966), Kamba (4,663,910), Somali (2,780,502), Kisii (2,703,235), Mijikenda (2,488,691), Meru (1,975,869), Maasai (1,189,522), and Turkana (1,016,174). The North Eastern Province of Kenya, formerly known as NFD, is predominantly inhabited by the indigenous ethnic Somalis. Foreign-rooted populations include Arabs, Asians, and Europeans.
