Acton is an area of West London, England, within the London Borough of Ealing. It lies within the Historic County of Middlesex and consists of four wards, East Acton, Acton Central, South Acton and Southfield. North Acton, West Acton, East Acton, South Acton, Acton Green, Acton Town, Acton Vale and Acton Central are all parts of Acton. Acton means "oak farm" or "farm by oak trees", and is derived from the Old English āc (oak) and tūn (farm). Originally an ancient village, as London expanded, Acton was absorbed into the city. Since 1965, Acton equates to the east of the London Borough of Ealing, though some of East Acton is in the London Borough of Hammersmith and Fulham and a small portion of South Acton is in the London Borough of Hounslow. Central Acton is synonymous with the hub of commerce and retail on the former main road between London and Oxford (the Uxbridge Road); a reminder of its history is in its inns, which date back in cases to the late Tudor period as stopping places for travellers. Nowadays, the principal route linking London and Oxford (the A40 dual carriageway) bypasses central Acton, but passes through East Acton and North Acton.
Acton has a population of over 62,480 people. Acton also forms part of the Greater London metropolitan area which has a population of over 14,372,596 people.
