Political Party Links

Political Party Links (PolPaL) is a linkage key infrastructure project for the social sciences. PolPaL provides a unified linkage platform for identifying political entities across social science datasets.

PolPaL, inspired by Party Facts, provides new linkage features, broader metadata, and extended coverage. It offers researchers a comprehensive, consistent, and long-term foundation for studying political entities globally and historically.
