In the early part of 2015, the party secretaries of six of the eight Swedish Riksdag parties (plus the Feminist Initiative as the only other Swedish party represented in the European Parliament) agreed to take part in an online survey of their memberships, which would be administered through the Laboratory of Opinion Research (LORE) at the University of Gothenburg.
In May, these party secretaries distributed individualized links to an otherwise identical web-survey to their members via email. All parties, except for the Social Democrats, sent out the survey to the entire membership list. The Social Democrats sent the survey to a large randomly drawn sample from their membership list. When it was closed on July 3, a total of 10,392 Swedish party members had completed the survey.
The survey questions are grouped into six modules: socio-demographic, general political attitudes, reasons for and extent of enrolment, position within the party, activism, and perception of role and attitudes towards membership. The questions were developed in consultation with the Members and Activists of Political Parties (MAPP) research group in order to facilitate cross-national comparisons. The unique data generated from the Swedish party membership survey will allow researchers to investigate much more specific and rich questions about party members in Sweden.
