Washington Lobbyists Survey, 1956-1957 (ICPSR 7262)

Principal Investigator(s): Milbrath, Lester


This study interviewed a sample of registered lobbyists from Washington, DC, during the academic year 1956-1957. Questions investigated lobbyists' role in policy-making, their occupational history, interest in public affairs, reasons for becoming a lobbyist, and political activities. Other variables concern the respondents' relationships to the organizations they represented, where they tried to establish contact, techniques they used to do so, how their lobbying skills were acquired, and self-appraisal of their success. Of the 114 respondents included in the sample, 101 were actually interviewed. For the remaining 13, personal data as well as some information about their lobbying activities were obtained from public records and informal conversations. Demographic data include age, level of education, personal income, religious preference, party affiliation, marital status, and size of family.
