Cross-National Socio-Economic and Religion Data, 2005
This file assembles data from the United Nations Human Development Reports (HDR) and the Central Intelligence Agency (CIA) World Factbook. It includes data on economic, social and demographic variables for 316 countries, nations and regions around the world. This is an attempt to draw together numerous variables employed in cross-national research. [See More...]

Cross-National Socio-Economic and Religion Data, 2011
This file assembles data from the 2010 United Nations Human Development Report (HDR), the 2011 edition of the Central Intelligence Agency's (CIA) World Factbook and ARDA researchers' coding of the 2008 US Department of State International Religious Freedom (IRF) report. It includes data on economic, social and demographic variables for 252 countries and nations around the world. This is an attempt to draw together numerous variables employed in cross-national research. [See More...]

Data from the ARDA National Profiles, 2005 Update - Religion Indexes, Adherents and Other Data
This file assembles data from multiple sources, but many of the measures are from the ARDA's coding of the 2003 US State Department's International Religious Freedom Reports. This coding produced data on 195 different countries and territories (see Grim and Finke 2006 for a list of countries coded), but excluded the United States. Additional data on religious regulation and favoritism in the smaller countries not covered by the State Department Reports were provided by researchers at the World Christian Database. 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 and the Heritage Foundation, and various socio-economic measures from the United Nations. Measures for religious persecution (AESTIMA) and ethnic identity (DETHNIC) were added to this file in August 2007. [See More...]

Data from the ARDA National Profiles, 2011 Update - Religion Indexes, Adherents and Other Data
This file assembles data from multiple sources on 250 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 August 2011 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 Polity IV Project, the Heritage Foundation, the Correlates of War Project, and the CIRI Human Rights Data Project, and various socio-economic measures from the United Nations 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 from the ARDA National Profiles, 2016 and 2018 Updates - Religion Indexes, Adherents and Other Data
This 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.

International Religious Freedom Data, 2001
This file contains measures from the ARDA's coding of the 2001 U.S. State Department's International Religious Freedom Reports. This coding produced data on 196 different countries and territories (see Grim and Finke 2006 for list of countries coded), but excluded the United States. It also includes three indexes calculated from these data: Government Regulation of Religion index (GRI), Social Regulation of Religion index (SRI), Government Favoritism of Religion index (GFI) (see Grim and Finke, 2006). The ARDA also coded International Religious Freedom Reports for the years 2003 and 2005. All three years of data (2001, 2003, and 2005) are aggregated into a single dataset, International Religious Freedom Data, Aggregate File, which we recommend as the best data to use for most statistical models.

International Religious Freedom Data, Aggregate File (2001-2005)
This file contains aggregate measures from the ARDA's coding of the 2001, 2003, and 2005 U.S. State Department's International Religious Freedom Reports. This coding produced data on 196 different countries and territories (see below for list of countries coded), but excluded the United States. It also includes three indexes calculated from these data: Government Regulation of Religion index (GRI), Social Regulation of Religion index (SRI), Government Favoritism of Religion index (GFI) (see Grim and Finke, 2006). Data in this file represent mean coding responses for each variable from all three years of coding. [See More...]

International Religious Freedom Data, Aggregate File (2003-2008)
This file contains aggregate measures from the ARDA's coding of the 2003, 2005, and 2008 U.S. State Department's International Religious Freedom Reports. This coding produced data on 199 countries and territories (see below for list of countries coded), but excluded the United States. It also includes three indexes calculated from these data: the Government Regulation of Religion Index (GRI), the Government Favoritism of Religion Index (GFI), and the Modified Social Regulation of Religion Index (MSRI) [see Grim and Finke (2006) for more information on the GRI and GFI, and see below for more information on the MSRI]. Data in this file represent mean coding responses for three of each variable from all three years of coding unless otherwise noted. Many countries have scores on variables that are expressed as decimals, and which do not correspond with a value label in the variables' descriptions. These decimal values signify that a country's scores on these variables vary over the 2003, 2005 and 2008 Reports. [See More...]
