Oklahoma City itself sprawls into three neighboring counties (Cleveland, Canadian and Pottawatomie), so only its Oklahoma County wards are counted above. Nicoma Park and Midwest City sit directly against each other on the county’s east side and are sometimes confused by visitors; they are separate municipalities with separate governments.
