The ISSP evolved out of pre-existing general social surveys. Its origin was a bilateral collaboration between the respective national studies of National Opinion Research Center (NORC), University of Chicago and Zentrum fuer Umfragen, Methoden, und Analysen (ZUMA, now part of GESIS-Leibniz Institute of the Social Sciences), in Mannheim, Germany.
Go to International Social Survey Programme webpageThe International Social Survey Programme (ISSP) is an annual program of cross-national survey collaboration, covering a wide range of topics important for social science research. Since 1985 the ISSP provides international data sets, enabling cross-cultural and cross-temporal research. "Environment" is one of the eleven ISSP topic modules. Central themes are attitudes towards environment-related issues, such as environmental protection, respondents' behavior, and respondents' preferences regarding governmental measures on environmental protection.
This dataset includes two types of variables: 1) percentage of respondents choosing a particular response option, and 2) average response per country, unweighted, primarily because weights are unavailable for some countries. Correlation between weighted and unweighted means for countries that do provide weights is above .95 for most of the included variables and does not go below .89.
