Counties of Kenya

County governments were established in all 47 counties[5] after the general elections in March 2013. The counties' names are set out in the First Schedule of the Constitution.

Under the new constitution, Kenya is now divided into 47 counties for administrative purposes. They are grouped below according to the former province they were separated from, with their areas and populations as of the 2009[6] and the 2019 census:[7]

County governments are responsible for county legislation (outlined in article 185 of the Constitution of Kenya), executive functions (outlined in article 183), functions outlined in the fourth schedule of the constitution of Kenya, functions transferred from the national government through article 187 of the constitution of Kenya, functions agreed upon with other counties under article 189(2) of the constitution of Kenya, and establishment and staffing of a public service (under article 235 of the Constitution of Kenya).[10] The functions of governments assigned to counties by the fourth schedule of the Constitution of Kenya are:[11]

The county governor and the deputy county governor are the chief executive and deputy chief executive of the county, respectively.[13] The Independent Electoral and Boundaries Commission[14] shall not conduct a separate election for the deputy governor but shall declare the running mate of the person who is elected county governor to have been elected as the deputy governor.[15] Each county will be run by an executive committee, consisting of:

• A governor, elected directly by the people
• A deputy, elected as running mate of the successful candidate for governorship
• A number of committee members not exceeding a third (or ten where a county assembly has more than 30 members) of the members of the respective county assembly
• A county secretary,[16] nominated by the governor and approved by the county assembly, who will double up as head of the county public service, and secretary to the county executive committee[17]

Uniquely among democracies, Kenyan law requires governors to have a recognised university degree.[18]

The counties each have an assembly[19] whose members are elected from single-member constituencies known as wards.[20] There may also be a number of nominated members as is necessary to ensure that neither male nor female members constitute more than two-thirds of the assembly.[21] There will also be six nominated members to represent marginalised groups (persons with disabilities, and the youth) and a county assembly speaker who will be an ex officio member of the assembly.[22]
