Situated in Western part of Kenya, Nyamira County has historically evolved from different and previous administrative units, creations and boundaries since independence. It is indeed formed part of one of the divisions of the larger Kisii district way back in 1970s. Nyamira as a division became a full district in 1987 curved out of the Kisii district; this had ever existed with various administrative and political boundaries. Before the devolution, Nyamira had three constituencies, five districts, 14 divisions, 38 locations and 90 sub-locations. With the advent of the devolution in 2013 due to the new constitution, Nyamira forms part of the 47 County Governments in Kenya with one extra Constituency created and 20 electoral wards

The County is predominantly occupied by the Gusii Community. However, the northern and eastern parts of the County have got some different ethnic significance being Luos and Kipsigis respectively. These two ethnic groups are considered the minority in the county with the Luos further considered as the marginalized group. Unlike the Luo Community who permanently stays in the county, most of the Kipsigis are on transits basically because of the trade exchange. The Gusii community in the County is further classified into two major sub-clans being the Abagirango and the Abagetutu with several micro clans that trickle down into the extended and nuclear families.

Nyamira County is a member of the Lake Region Economic Bloc. The Lake Region Economic Bloc is made up of Bungoma, Busia, Homa Bay, Kakamega, Kisii, Kisumu, Migori, Nyamira, Siaya, Vihiga, Nandi, Bomet, Trans Nzoia and Kericho Counties. The common understanding of
the Bloc is for strategic connections between Counties with shared interests seated in a desire for mutual benefit can be an effective and intelligent means of increasing the possibility of creating notable development impact across several counties. The existence of other regional development
urgencies like the Lake Basin Development Authority and Lake Victoria South Water Works Development Agency has spared development in their line interventional areas in the County. The Agencies cover Bomet, Homa-Bay, Kericho, Kisii, Migori, Nyamira, Kisumu and Siaya Counties

The County has inter county relations; along the Homabay County (Rachuonyo) border there is ethnic intermarriages, this is evident in Miruka and Nyamusi areas that has promoted peace coexistence. Miruka, Chebilat and Keroka markets along the borders of Homabay, Bomet and Kisii counties respectively have promoted exchange of goods and services for the people living along these borders. The existence of the tea zones in Kericho and Nyamira counties has promoted employment among the tea factories and the dwellings.
