(from Greek psephos
ψῆφος, 'pebble', which the Greeks used as ballots) is the statistical
analysis of elections
. Psephology uses compilations of precinct voting returns for elections going back some years, public opinion polls
, campaign finance
information and similar statistical data. The term was coined in the United Kingdom
by historian R. B. McCallum
to describe the scientific analysis of past elections. In Britain the term occasionally appears in scholarly literature.
Psephology also has various applications specifically in analysing the results of election returns for current indicators, as opposed to predictive purposes. For instance, the Gallagher Index measures the disproportionality of an election.
