Nairobi County Sub-Counties, Wards & Locations 2026

ByNairobi Postal Codes

Nairobi County, designated as County 047, is Kenya’s capital and largest urban center with a population of over 4.3 million residents according to the 2019 census. The county operates under a devolved government structure established by Kenya’s 2010 Constitution, with its administrative framework divided into 17 sub-counties (constituencies) and 85 electoral wards.

Nairobi County’s governance operates through a hierarchical system:

  • County Executive: Led by the Governor and 10 County Executive Committee (CEC) members
  • Sub-County Administrators: Manage the 17 sub-counties
  • Ward Administrators: Oversee the 85 wards
  • Chiefs and Assistant Chiefs: Supervise villages and locations

Sub-counties serve as constituencies represented by Members of Parliament (MPs) at the national level. In contrast, wards are represented by Members of the County Assembly (MCAs) who legislate on county matters.
