Mombasa County is one of the 47 counties of Kenya. Its capital is Mombasa. In terms of economy it is second after Nairobi.[1] Initially it was one of the former districts of Kenya but in 2013 it was reconstituted as a county, on the same boundaries. It is the smallest county in Kenya, covering an area of 229.7 km2 excluding 65 km2 of water mass. The county is situated in the south eastern part of the former Coast Province. It borders Kilifi County to the north, Kwale County to the south west and the Indian Ocean to the east. Administratively, the county is divided into seven divisions, eighteen locations and thirty sub-locations.
Kenya was divided into eight provinces prior to 2013, which were subdivided into 47 counties. In the former Coast Province there are six counties, Mombasa being one of them. It is situated in the southeast of Coast Province. It is the smallest in size, covering an area of 212.5 km2.[2] The county lies between latitudes 3°56′ and 4°10′ south of the equator and longitudes 39°34′ and 39°46′ east.[1]
The county and the city are divided into four divisions:
Mombasa is an urban city county and for this reason, there is a large population of both local and immigrant communities. The local communities include the Mijikenda, Swahili and Kenyan Arabs. The Mijikenda is the largest community in Mombasa County making up almost 35% of the total population in the county. The immigrant Kamba community is the second largest ethnic community in the county making almost 30% of the total population of the county. The Kamba people have been known for their expansive knowledge of business and trade ranging from small scale to large scale followed closely by their GEMA counterparts. Other significant immigrant communities include the Luo, Luhya and Somali communities.
The county is composed of six Parliamentary constituencies:[3]
