    1 The Religion and State (RAS) Project is a university-based project located at Bar Ilan University in Ramat Gan, Israel and is directed by Jonathan Fox. Round 3 of the RAS includes all countries with populations of 250,000 or more as well as a sampling of smaller states and offers annual measures from 1990 to 2014. The methods used for conducting the RAS3 collection and the complete codebook can be reviewed online. Or, the codebook and data file can be downloaded free of charge here. For details on how the RAS indexes reported on the ARDA’s National Profiles were coded, constructed, and placed into categories, click here.

    3 The U.S. State Department's International Religious Freedom Report is submitted to Congress annually by the Department of State in compliance with Section 102(b) of the International Religious Freedom Act (IRFA) of 1998. This report supplements the most recent Human Rights Reports by providing additional detailed information with respect to matters involving international religious freedom. It includes individual country chapters on the status of religious freedom worldwide. A dataset with these and the other international measures highlighted on the country pages can be downloaded from this website. These State Department reports are open source.

    4 The Religious Characteristics of States Dataset Project: Demographics reports the estimates of religious demographics, both country by country and region by region. The RCS was created to fulfill the unmet need for a dataset on the religious dimensions of countries of the world, with the state-year as the unit of observation. It estimates populations and percentages of adherents of 100 religious denominations including second level subdivision within Christianity and Islam. The RCS Data Project would like to acknowledge, recognize, and express our deepest gratitude for the significant contributions of Todd M. Johnson the co-principal investigator of the World Religion Database.

    5 Relying on agencies from each country, as well as a synthesis of data from United Nations divisions, Eurostate Demographic statistics, the U.S. Census international database, and its own data collection, the World Bank's Open Data site offers free and open access to data about development in countries around the globe.

    6 The Center for Systemic Peace (CSP) is engaged in innovative research on the problem of political violence within the structural context of the dynamic global system. The Center supports scientific research and quantitative analysis in many issue areas related to the fundamental problems of violence in both human relations and societal-systemic development processes. The Center continually monitors political behavior in each of the world's major states and reports on emerging issues and persisting conditions related to the problems of political violence and "state failure." A dataset with these and other international measures can be downloaded from here. Used with permission. *Note: Polity Scores range from -10 to 10 and include the following categories: -10 to -9: strongly autocratic, -8 to -7 autocratic, -6 to -4 weakly autocratic, -3 to +3 anocratic, +4 to +6 weakly democratic, +7 to +8 democratic, +9 to +10 strongly democratic.

    7 Varieties of Democracy (V-Dem) is a new approach to conceptualizing and measuring democracy. V-Dem provides a multidimensional and disaggregated dataset that reflects the complexity of the concept of democracy as a system of rule that goes beyond simple presence of elections. The V-Dem project distinguishes between seven high-level principles of democracy: electoral, liberal, participatory, deliberative, egalitarian, majoritarian, and consensual, and collects data to measure these principles. A dataset with these and other international measures can be downloaded from here. Used with permission.

    8 The Religious Characteristics of States Dataset Project: Government Religious Preference (GRP) measures government-level favoritism toward, and disfavor against, 30 religious denominations. A series of ordered categorical variables index the state's institutional favoritism in 28 different ways. The variables are combined to form five composite indices for five broad components of state-religion: official status, religious education, financial support, regulatory burdens, and freedom of practice. The five components' composites in turn are further combined into a single composite score, the GRP score. The RCS Data Project would like to acknowledge, recognize, and express our deepest gratitude for the significant contributions of Todd M. Johnson, the principal investigator of the World Christian Database, the co-principal investigator of the World Religion Database, and co-author of the World Christian Encyclopedia series.

    11 The World Values Survey is a worldwide investigation of socio-cultural and political change. It is conducted by a network of social scientists at leading universities around the world. Interviews have been carried out with nationally representative samples of the publics of more than 80 societies. A total of four waves have been carried out since 1981. The ARDA has averaged the weighted responses across the waves for each country surveyed. The average responses for all countries have been placed in a single file and can be previewed and downloaded here. See the World Values Survey website for further information and to download the original survey data: http://www.worldvaluessurvey.org/.

    12 Freedom House is an independent non-governmental organization that offers measures of the extent to which governments are accountable to their own people; the rule of law prevails; and freedoms of expression, association, belief and respect for the rights of minorities and women are guaranteed.

    13 The CIA's World Factbook was created as an annual summary and update to the now defunct National Intelligence Survey (NIS) studies. The first classified Factbook was published in August 1962, and the first unclassified version was published in June 1971. The NIS program was terminated in 1973 except for the Factbook, map, and gazetteer components. The 1975 Factbook was the first to be made available to the public with sales through the US Government Printing Office (GPO). The year 2010 marks the 67th year of the World Factbook and its predecessor programs. The maps and flags are also from the World Factbook, which is an open source.

    16 The United Nations Human Development Reports provide data and statistical analysis in various areas of human development. The Human Development Report (HDR) presents two types of statistics: the human development indicator tables, which provide a global assessment of country achievements in different areas of human development, and thematic statistical analysis. A dataset with these and the other international measures highlighted on the country pages can be downloaded from this website. Used with permission.

    17 The 2013 Gender Inequality Index is a composite measure reflecting inequality in achievements between women and men in three dimensions: reproductive health, empowerment and the labor market. It varies between zero (when women and men fare equally) and one (when men or women fare poorly compared to the other in all dimensions). The health dimension is measured by two indicators: maternal mortality ratio and the adolescent fertility rate. The empowerment dimension is also measured by two indicators: the share of parliamentary seats held by each sex and by secondary and higher education attainment levels. The labor dimension is measured by women’s participation in the work force.

The 2003, 2005, and 2008 reports were coded by researchers at the Association of Religion Data Archives. The GRI, GFI and SRI values reported on the National Profiles are averages from the 2003, 2005, and 2008 International Religious Freedom reports, while the Religious Persecution measure is an average from the 2005 and 2008 reports. All other measures derived from the International Religious Freedom reports were coded from the reports 2008.
