This volume consists of an index of questions repeated in public opinion surveys, and the variants of these questions. The questions included are drawn from American national samples (primarily of the general population) conducted by AIPO (Gallup) NORC, and Roper, and archived at the Roper Public Opinion Research Center. The basic data for over 90 percent of the surveys cited are available only from the Roper Center. The earliest survey included in this index was undertaken in September, 1936, and the most recent survey in October, 1973. The purpose of the index is to make accessible a data base for the measurement and analysis of social change. Seventy major topics comprised of specific research questions range from agricultural farm income trends to Americans' attitudes toward Yugoslavia. Each entry consists of the question wording, the survey organization which asked the question, the number and date of the survey, and the number of the question. As an aid to researchers undertaking secondary analysis of survey data, Norval D. Glenn has written a guide to survey archive research. Also included are a list of publications on the study of social change using survey data from the Roper Center; a summary of the procedures used in compiling the index; and information on code categories for demographic background question and changes in survey sampling procedures.
