Public Interest Organizations
Foundation for Public Affairs
Earlier versions of tables 1.1–1.4 were published in “More Bang for the Buck: The New Era of Full-Service Public Interest Organizations,” in Allan J. Cigler and Burdett A. Loomis, eds. Interest Group Politics, 3d edition. The explanation of the comparability of the data sets provided in that chapter, modified and reproduced below, is equally applicable to the analyses presented here: The Berry data presented in chapter 1 were drawn from chapters 2 and 3 of Lobbying for the People. The Foundation for Public Affairs data sets were drawn from the foundation's publications, Public Interest Profiles (1986–1987, 1992–1993, 1996–1997). For each public interest group that is presented below, seventy-eight variables were coded from the raw data presented in each profile.
To analyze further the comparability of the two data sources, those organizations included in both sets (N = 35) were analyzed and data for an additional fourteen organizations not found in the Foundation for Public Affairs publication were pieced together. The tables presented in this chapter were replicated using data from the forty-nine groups available for both data sources as well as from additional data gathering. Aside from the finding in table 1.1 on year of origin, the patterns uncovered in the full analysis of all Berry groups and FPA groups are comparable to those in the smaller “panel” study. Any variation in the two data sources reflects changes made in the public interest sector during the intervening thirteen years between the two studies. Sample sizes reported for the tables in chapter 1 differ due to missing values in the data sets.
