The paper examines the present state of voluntary associations in Estonia—their resources and fields of activity. First, the paper discusses two possible functions of nongovernmental organizations (NGOs) in the postsocialist social change: the opening up of participation channels complementary to those of representative democracy and the support to the state in fulfilling social welfare functions. A view stressing the latter function of the voluntary sector has hitherto dominated Estonian domestic political discussion. The actual capacity of Estonian NGOs is assessed on the basis of previous research and the results of a mail survey (779 responding organizations). The resources of the respondents are smaller than expected. Resources differ greatly between urban and rural associations, and between NGOs representing different fields of activity. The paper concludes with a discussion of the empirical findings and of the need for further research.
