The International Social Survey Program (ISSP) is an ongoing program of crossnational collaboration. Formed in 1983, the group develops topical modules dealing with important areas of social science as supplements to regular national surveys. This collection, the third module in the series, contains data from Australia, Austria, the Federal Republic of Germany, Hungary, Italy, the Netherlands, Great Britain, the United States, Poland and Switzerland. Questions asked of respondents focused on equality of income, wealth, and opportunity. Respondents were asked for their perceptions of the extent of present inequality, explanations for inequality, and support for government programs to reduce inequality. Demographic data on respondents such as age, sex, employment, income, marital status, education, religion, political affiliation, and trade union membership also are provided.
