This study analyses if and to what extent culture, associational membership, social trust, civic participation, and political ideology explain the PSM level of civil servants. On the basis of a representative sample of 3,754 municipal employees from the German- (79 percent) and the French-speaking (21 percent) parts of Switzerland, this study offers three striking pieces of empirical evidence. First, the social profile of the respondents is different for each PSM dimension: “Attraction to politics and policymaking” is mostly influenced by political participation and sympathy for political parties; “Commitment to the public interest ” by culture and social trust; “Compassion” by clear-cut political positioning; and “Self-Sacrifice ” by volunteering and religiosity. Second, socio-political variables add an important contribution to the explanation of the first three dimensions. And third, cultural belonging has an important effect on the level of PSM.
