The district expanded as the built up area grew and stretched some distance into rural land. When county police were set up in England the forces of Essex, Hertfordshire, Kent and Surrey did not include those parts of the counties within the MPD and Middlesex did not have a county force.

It occupies much of the central area of Greater London including most of the West End.
