Over the past twenty-five years, a field of research into the careers of Members of European Parliament (MEPs) has developed. Drawing on a massive amount of accessible open data, we have assembled an updated database comprising all MEPs between 1979 and September 2019. This dataset contains (some) socio-demographic informations about MEP’s and their carreer paths in EP. Data were scraped from the EP website. Metadata are filled separately in a rich text format (.rtf) document.
