In contribution to current debates on the changing roles and responsibilities of civil society in welfare state arrangements, I examined the participation of various types of civil society organizations in national welfare policymaking in Sweden between 1958 and 2012. Drawing upon an extensive dataset of over 1400 civil society, state, and for-profit organizations, I tested three claims related to the role and responsibility of civil society in the governance of welfare: the changing balance between corporatist and welfare organizations, the shift from voice to service, and another shift from nonprofit organizations to FPOs. My results revealed weak but emerging trends aligned with changing patterns of corporatism and the marketization of Sweden’s welfare system. However, support for any shift from voice to service remains uncertain.
