Ewell ( YOO-əl, inf. YOOL) is a town in Surrey, England, 12 miles (19 kilometres) south of central London and two miles (three kilometres) northeast of Epsom. At the 2011 Census, it had a population of 34,872. The majority (73%) was in the ABC1 social class, except the Ruxley Ward that is C2DE. Ewell was founded as a spring line settlement, where the permeable chalk of the North Downs meets the impermeable London Clay, and the Hogsmill River (a tributary of the River Thames) still rises at a spring close to Bourne Hall in the village centre.
