The parish covers a number of settlements:
Unlike the ecclesiastical parish of Cassop-cum-Quarrington with Bowburn, the civil parish does not include Quarrington Hill.
The civil parish was created in 1887 from the townships of Cassop and Quarringon with boundary changes in 1946 and 1953 (the latter changes moving much of the newly built Bowburn Estate into the parish from Whitwell House).
The parish was divided into two wards from the May 2013 elections. The division between the two is marked by the A1(M) motorway.
- East Ward - consisting of Bowburn and Tursdale has 11 councillors
- West Ward - consisting of Cassop, Parkhill, Old Cassop and Old Quarrington has 4 councillors.
In 2013 15 Labour Party Candidates and 1 Independent were elected as Parish councillors.
