Coming soon
A comprehensive dataset of approximately 400,000 press releases from over 150 parties across 30 countries, extending coverage until 2025. This expanded dataset builds upon the original PARTYPRESS database to provide broader comparative coverage of party communication strategies and issue salience across diverse political systems.

Election Dataset Germany 1953-2021 and 1953-2017: County-level results made comparable over time using geodata and areal weighted interpolation
Cornelius Erfort
This repository provides historic, comparable county-level election results for West Germany since 1953 in the borders of 2017 and 2021 counties. These can be easily merged with other historic data on the county level using offical county ID numbers (AGS, Allgemeiner Gemeindeschlüssel) that are also provided. The final dataset contains estimates for the vote share of all major parties for each election from 1953-2017/2021 (within the boundaries of the 2017/2021 counties) obtained from areal weighted interpolation.
