CitationMataic, D., & Finke, R. (2023, March 16). Data from the ARDA National Profiles, 2016 and 2018 Updates - Religion Indexes, Adherents and Other Data
SummaryThis file assembles data from multiple sources on 256 countries and territories, and also aggregates this data globally and by 22 world regions. The file presents most of the data available on the ARDA National Profiles as of 2018 in a single downloadable dataset. Many of the measures are from the ARDA's coding of the 2008 US State Department's International Religious Freedom (IRF) Reports. This coding produced data on 198 different countries and territories (see the Summary file for the International Religious Freedom Data, 2008 for a list of countries coded, available for download from the ARDA), but excluded the United States. In addition, this project assembled (with permission) other cross-national measures of interest to researchers on religion, economics, and politics. They include adherent information from the World Christian Database, scales from Freedom House, the Religion and State Project, the Center for Systemic Peace, the Heritage Foundation, the Correlates of War Project, the Varieties of Democracy Project, the CIRI Human Rights Data Project, and various socio-economic measures from the United Nations, World Bank, and the CIA's World Factbook. The source of each variable in this dataset is acknowledged in the variable's description, except in the case of those variables generated by ARDA researchers' coding of the Department of State's IRF Reports.
Data FileCases: 275
Weight Variable: None
Data Collection2016 and 2018
Funded ByData collection was funded by the John Templeton Foundation.
Collection ProceduresMany of the measures in this file are based on the 2008 U.S. Department of State's International Religious Freedom Reports. These reports were assigned quantitative measures by using a coding instrument, essentially a survey questionnaire. The questions included measures for specific acts of discrimination, prejudice, persecution, warfare, property rights, forced migration, and other acts that might (or might not) be related to the religious life of the country. For all variables, the coders were asked to make substantive observations of the qualitative data and to base their codes on empirical observations of actions or patterns of behavior that were documented in the reports. For a fuller description of the coding procedures, see Grim and Finke (2006).

Additional Data SourcesThe 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.

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.
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.
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.
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.
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.
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.
Data under the "Features of Constitution" heading are drawn from coding of the U.S. State Department's 2008 International Religious Freedom Reports conducted by researchers at the Association of Religion Data Archives. The article by Brian Grim and Roger Finke describes the coding of the International Religious Freedom reports.

Text from country constitutions was copied from primary documents obtained online using a variety of sources, including the Constitute Project, World Constitutions Illustrated, and government sources. When the text was in a language other than English, it was translated to English by ARDA staff or with web-based translation utilities such as Google Translate. Emphases were added to the text by ARDA staff to differentiate religious content from non-religious content. Text is current to the date listed in the "Current as of" field shown above.

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/.
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.

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.
The Heritage Foundation/Wall Street Journal Index of Economic Freedom is a systematic, empirical measurement of economic freedom in countries throughout the world. A set of objective economic criteria are used to study and grade various countries for the annual publication of the Index of Economic Freedom.

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 article by Brian Grim and Roger Finke describes the coding of the U.S. State Department's International Religious Freedom reports. 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. A data file with all of the 2008 coding, as well as data files with other cross national collections are available for preview and download from the data archive on this site. Used with permission.
The Cingranelli-Richards (CIRI) Human Rights Dataset contains standards-based quantitative information on government respect for 15 internationally recognized human rights for 202 countries, annually from 1981-2011. It is designed for use by scholars and students who seek to test theories about the causes and consequences of human rights violations, as well as policy makers and analysts who seek to estimate the human rights effects of a wide variety of institutional changes and public policies including democratization, economic aid, military aid, structural adjustment, and humanitarian intervention.
