Marginality and Turnout in British General Elections

One of the most striking features of British general election results is the large variation in turnout from one constituency to another. In the 1970 election, for instance, turnout in Britain ranged from 44–9 per cent in Stepney to 85–3 per cent in Cornwall North. Moreover, the variation in turnout has become greater in recent years. While the mean turnout in general elections has tended to fall, the standard deviation of turnout has increased steadily from 5–3 in the 1955 election to 6–9 in the 1970 election. With the exception of the Nuffield studies, however, there have been few attempts to investigate this variation. Political scientists have concentrated instead on describing and attempting to explain differences in turnout between different social and demographic groups.
