Summary
"Between October 2011 and November 2012, Pew Research Center, with generous funding from The Pew Charitable Trusts and the John Templeton Foundation, conducted a public opinion survey involving more than 30,000 face-to-face interviews in 26 countries in Africa, Asia, the Middle East and Europe. The survey asked people to describe their religious beliefs and practices, and sought to gauge respondents; knowledge of and attitudes toward other faiths. It aimed to assess levels of political and economic satisfaction, concerns about crime, corruption and extremism, positions on issues such as abortion and polygamy, and views of democracy, religious law and the place of women in society.
"Although the surveys were nationally representative in most countries, the primary goal of the survey was to gauge and compare beliefs and attitudes of Muslims. The findings for Muslim respondents are summarized in the Religion & Public Life Project's reports The World's Muslims: Unity and Diversity and The World's Muslims: Religion, Politics and Society, which are available at www.pewresearch.org. [...] This dataset only contains data for Muslim respondents in the countries surveyed. Please note that this codebook is meant as a guide to the dataset, and is not the survey questionnaire." (2012 Pew Religion Worlds Muslims Codebook)
Data were weighted to account for differences in probability of selection. Where necessary, survey results were weighted to match the demographic characteristics of the population in each country and to account for the oversampling of Muslims. This variable does not combine all 39 countries into a single global sample that accounts for population differences. It should only be used for analyses of national populations and subgroups of national populations.
Results for the survey are based on face-to-face interviews conducted under the direction of the Opinion Research Business in Algeria, Iran, Iraq, Morocco and Tunisia and Princeton Survey Research Associates International in the other 21 countries. All surveys are based on national samples except in Thailand, where a sample of only Muslims was fielded in five southern provinces.
