 A slightly broader definition used by the Office for National Statistics (ONS) includes developed areas adjoining Bristol but outside the city-council boundary, such as Whitchurch village, Filton, Patchway and Bradley Stoke, but excludes undeveloped areas within that boundary. The ONS has defined a Bristol Urban Area, which includes Kingswood, Mangotsfield, Stoke Gifford, Winterbourne, Frampton Cotterell, Almondsbury and Easton in Gordano. The North Fringe of Bristol, a developed area in South Gloucestershire between the Bristol city boundary and the M4 and M5 motorways, was so named as part of a 1987 plan prepared by the Northavon District Council.
