This, the 13th annual volume of the "Index to International Public Opinion", includes data from public opinion polls dealing with more than 145 countries and geographical regions. All tables contain total sample results, and many include analysis by various population sub-groups, such as age, sex, education, economic levels, national regions, and religion. As has been the case since the initial volume, the survey questions deal with key social, political and economic issues of contemporary as well as historical interest. This volume contains data from surveys conducted mainly during the period from Spring 1990 to Spring 1991. For trend analysis purposes, a number of time series tables are included covering a decade or more. The volume is organized by major topic categories, each of which is subdivided into more specific subject groups. Beyond the subject categorizations, the countries in which the polls were conducted are ordered alphabetically. The volume concludes with a three-part subject index. As an ongoing reference source for public opinion data, this volume as well as its predecessor volumes should prove invaluable for scholars of social, political, and economic issues, for business leaders, journalists, and government officials.
