The concept of a neighbourhood effect within British voting patterns has la
rgely been discarded, because no data have been available for testing it at
the appropriate spatial scales. To undertake such tests, bespoke neighbour
hoods have been created around the home of each respondent to the 1997 Brit
ish Election Study survey in England and Wales, and small-area census data
have been assembled for these to depict the socio-economic characteristics
of voters' local contexts. Analyses of voting in these small areas, divided
into five equal-sized status areas, provides very strong evidence that mem
bers of each social class were much more likely to vote Labour than Conserv
ative in the low-status than in the high-status areas. This is entirely con
sistent with the concept of the neighbourhood effect, but alternative expla
nations are feasible. The data provide very strong evidence of micro-geogra
phical variations in voting patterns. for which further research is necessa
ry to identify the processes involved.
