About the CLD

The Comparative Legislators Database (CLD) is a one-stop shop for rich, diverse and integrated individual-level data on national political representatives. The database contains information for over 67,000 contemporary and historical legislators from 16 countries. It unites collaborative micro-data collection efforts and brings these together through the integration of data from Wikipedia, Wikidata, and other sources.
