English language in southern England
South East England and the Home Counties (the counties bordering London) tend to reflect the interface between the London region and other regional accents. Affluent districts are associated with a modified Received Pronunciation (RP) accent, reflecting their traditional popularity with upper middle and upper-class residents which has spread throughout more social classes broadly in rural areas with commuting access to London. Less affluent areas have traditionally mainstream London accents (that is, variants of the Estuary English accent) that grade into southern rural outside urban areas.
English language in England
In the 1950s and 1960s the Survey of English Dialects was undertaken to preserve a record of the traditional spectrum of rural dialects that merged into each other. The traditional picture was that there would be a few changes in lexicon and pronunciation every couple of miles, but that there would be no sharp borders between completely different ways of speaking. Within a county, the accents of the different towns and villages would drift gradually so that residents of bordering areas sounded more similar to those in neighbouring counties.
