Kiambu County has 12 constituencies with wards ranges from four to eight wards per constituency. Every Constituency has an elected Member of Parliament (MP) who represents the residents in the National Assembly while every ward has an elected Member of County Assembly (MCA) who represents the residents in the County Assembly. The County therefore has 12 elected Members of Assembly and 60 elected Members of County Assembly.
Ruiru Constituency has the highest number of wards (8) while Gatundu North, Gatundu South and Kiambu constituencies have the least with each having 4 wards. Ruiru Constituency is also densely populated thus exerting pressure on the available resources. The County should therefore plan to implement programmes aimed at upgrading the existing infrastructure such as road, housing, water among others in the densely populated areas in order to accommodate the rising population.
