[3] Its area has been partly absorbed by the growth of London; with its name reused for the modern housing development of Chafford Hundred.

Hundred meetings are thought to have taken place in Chafford Heath[4] (grid reference TQ564836) in the southern part of the ecclesiastical parish of Upminster.

The hundred contained the parishes of Aveley, Brentwood, Childerditch, Cranham, Grays Thurrock, Great Warley, Little Warley, North Ockendon, Rainham, South Ockendon, South Weald, Stifford, Upminster, Wennington and West Thurrock.

[5] The hundred covered a narrow area stretching 12 miles (19 km) northwards from the river.

By 1894 they were effectively replaced by a system of uniform local government districts, which were consolidated over time and finally replaced by the London boroughs (1965) and non-metropolitan districts (1974), further change occurred in 1998 when Thurrock became a unitary authority.
