This, the 16th volume of the Index to International Public Opinion, provides data from opinion surveys conducted in 64 countries. Approximately 98 countries and geographical areas are referenced in these studies. The data were contributed by 166 survey research firms. As has been the case with previous volumes, all tables contain total sample results, and many include analysis by various population subgroups such as age, education level, gender, religious affiliation, and political party identification. As in the past, poll questions deal with a broad mix of social, political, and economic issues of both contemporary and historical interest.

Volume 16 includes data from polls conducted for the most part during the period Spring 1993 through Spring 1994. In addition, for trend analysis purposes, a number of time series tables covering a decade or more are included. There is also a section entitled Changing Opinions: A 50-Year Retrospective. This part of the Index contains polling data gathered approximately a half century ago in a number of different countries. This volume and the overall series provide the most comprehensive source for public opinion data available. As such the volumes are of unusual importance for journalists, professional scholars, government officials, and business leaders.
