Within the Church of England, a diocese is a geographical area representing a regional worshipping community in the UK. The geographical boundaries of the Diocese of Derby and the County of Derbyshire are virtually identical.
The Diocese is divided further into 16 Deaneries: seven in the Chesterfield Archdeaconry and nine in Derby Archdeaconry. There are 330 Church of England churches in the Diocese with 220 licensed clergy and 300+ licensed lay readers.
