Analysis
Religious identification
In each country surveyed, people were asked about their current and childhood religious identification. We only analyzed religious groups with large enough sample sizes. But respondents of other religious backgrounds were not excluded from the surveys, even if their religious group was not able to be analyzed separately. In the U.S. for example, the survey included Sikhs, Wiccans, followers of Native American religious traditions, and others, though there were not enough respondents from these smaller groups to report on their answers separately. Refer to the report Topline for additional information.
Education
To compare educational groups across countries, we standardize education levels based on the United Nations’ International Standard Classification of Education (ISCED).
