Investigating differences in electoral turnout: the influence of ward-level context on participation in local and parliamentary elections in Britain

Electoral turnout is an important measure of the health of a liberal democracy. Although research identifies factors that affect electoral participation, we still know little about how electors in a specific location respond to opportunities to vote for different kinds of local, national, and supranational institutions. This paper addresses this issue by analysing the relative rates of turnout at local, parliamentary, and European elections within three time periods for the London Borough of Brent. It uses turnout data for individual polling districts to investigate whether relative differences in turnout are sustained across time, whether polling districts perform consistently or not for different types of elections and whether variations in turnout are related to marginality. The results indicate that turnout at different types of elections is not stable even within tightly constrained time periods and that there are statistically significant differences in the relative rates of participation between polling districts. Geographically, the differences in relative rates of turnout appear to be spatially clustered, particularly with respect to local elections and this may reflect an increase in the concentration of party campaigning in marginal wards.
