The contrast is striking. Kajiado North covers just 111 square kilometres, about half of one per cent of the county, yet it holds more than a quarter of the people, because Ngong and Ongata Rongai have grown into Nairobi’s suburbs. Kajiado West is the largest constituency at 7,862 square kilometres but one of the least populated.

How Wards Work
A ward is the smallest electoral unit in Kenya. Voters in each ward elect an MCA, who sits in the Kajiado County Assembly to represent the ward, pass county laws and oversee the county executive. You can see what MCAs earn in our guide to MCA salaries in Kenya. Each ward is also an administrative unit, with a ward administrator who coordinates county services such as bursaries and projects. The CIDP counts 135 villages under the wards.
Ward boundaries are set by the Independent Electoral and Boundaries Commission (IEBC). To find your ward, check your voter registration details with the IEBC or look at the polling station where you vote.
