Electoral System Design Project

This project, collaborative with Simon Hix (London School of Economics) examines all elections between 1945-2006 in democracies with populations over one million — 610 elections in all, from 81 countries.  The dataset contains information on constitutional design and electoral rules (including mean and median magnitudes of districts in each election, legal thresholds, mixed-member formats), on disproportionality and party system fragmentation, on various indicators of political economy (growth rates, government spending, surpluses/deficits, inequality, human development index), and on demographic and historical information.  There are two files, the data and a codebook:
