CLEA Lower Chamber Elections Archive

The dataset currently includes 1,870 elections from 162 countries and territories.

GeoReferenced Electoral Districts

The goal of this project is to offer maps formatted in a manner so they can be linked to other standard geo-referenced data, allowing researchers to test a variety of research questions at a subnational level.

The party nationalization datasets contain the effective number of parties, as well as several measures of party nationalization, at three different levels of aggregation: the national level, the party level, and the constituency level.
