The WARP dataset is a comprehensive and ongoing data collection effort that provides information about the numerical presence of age groups in lower house parliaments, spanning across the globe and over time.
To date, it contains over 800 elections in 150 countries. In more detail, we provide information on the mean and median age of Members of Parliament (MPs), as well as information of the share of young or older MPs. It also provides figures that compare the presence of a certain age group of legislators in relation to the same age group in the general population. Finally, it includes gendered figures, such as the presence of young female MPs.
Notes: If more than one observation is listed per year, the latest available data is taken as a country score of the given year. We also underline that the WARP dataset coverage of MPs changes across years and countries, and coverage data can be obtained from the original website.
