This data wasa collected for the project "Political Parties and Democracy: Decline or Change?" The aim of "Political Parties and Democracy: Decline or Change?" is to illustrate various aspects of party policy development, which can give us new and improved knowledge about challenges and the behavious concerning democracy and the parties in the 21st century. We are particularly interested in the dynamics of the relationship between voters, party members, candidates and political leadership, with regard to public opinion formation, policy development as well as recruitment for public office at the national level. Another main subject is the parties' development as arenas for political participation. The project has therefore in the spring of 2009 conducted two separate surveys among the seven largest parties in Norway; one with Norwegian Party Congress delegates in spring 2009 and one with a representative sample of party members. Data from "Norwegian Party Congress Delegate Survey, 2009" are made available for research purposes (including phd and master theses) when ordered if there is documentation showing that a data protection official or the Norwegian Data Protection Autority has been notified, or a data processing agreement has been made with UiO. Researchers who wish to have access to this data are sworn to secrecy and must sign a declaration of confidentiality/loan agreement. In some cases, NSD can facilitate an anonymized version of the dataset
