U.S. Religion Census: Religious Congregations and Membership Study, 2010 (County File)

This study, designed and carried out by the Association of Statisticians of American Religious Bodies (ASARB), compiled data on the number of congregations and adherents for 236 religious groups in each county of the United States. Participants included 217 Christian denominations, associations, or communions (including Latter-day Saints, Messianic Jews, and Unitarian/Universalist groups); counts of Jain, Shinto, Sikh, Tao and National Spiritualist Association congregations, and counts of congregations and adherents from Bahá'ís, three Buddhist groupings, four Hindu groupings, four Jewish groupings, Muslims and Zoroastrians. The 236 groups reported a total of 344,894 congregations with 150,686,156 adherents, comprising 48.8 percent of the total U.S. population of 308,745,538 in 2010.

General Social Survey, 1991

The General Social Surveys (GSS) have been conducted by the National Opinion Research Center annually since 1972, except for the years 1979, 1981, and 1992 (a supplement was added in 1992), and biennially beginning in 1994. The GSS are designed as part of a program of social indicator research, replicating questionnaire items and wording in order to facilitate time-trend studies. Items on religion include religious preference, church attendance, beliefs about the Bible, attitudes toward organized religion and its opponents, and more. In addition, it contains a special module examining respondents' images of God. The survey also contains a topical module on work organizations.

Spiritual Life Study of Chinese Residents

The lack of quality data has left academia with an unclear picture of what religious life is like in China. Much of what is known comes from government statistics, anecdotal reports from missionaries and religious organizations, or field research. The objective of this study was to design and collect a state of the art random sample of Chinese citizens and assess their religious and spiritual life. A high quality team of Chinese scholars was assembled for the project. The survey was designed in fall 2006. In the spring of 2007, Dr. Anna Sun led a research team to field test the survey in China. In May 2007 the data were collected. The survey was a face-to-face interview. Respondents were selected using a multi-stage method to select metropolitan cities, towns and administrative villages. The final survey was administered in 56 locales throughout China, including 3 municipal cities (Beijing, Shanghai, Chongqing), 6 province capital cities (Guangzhou, Nanjing, Wuhan, Hefei, Xi'an and Chengdu). In addition, 11 regional level cities, 16 small towns, and 20 administrative villages were sampled. Within each locale, households were sampled within neighborhoods, and neighborhoods were sampled within administratively defined total neighborhood committees (government defined collections of neighborhoods). A KISH grid procedure was used to randomly select one respondent from each household for a face-to-face in-home interview.

U.S. Religion Census: Religious Congregations and Membership Study, 2010 (State File)

This study, designed and carried out by the Association of Statisticians of American Religious Bodies (ASARB), compiled data on the number of congregations and adherents for 236 religious groups in each county of the United States. Participants included 217 Christian denominations, associations, or communions (including Latter-day Saints, Messianic Jews, and Unitarian/Universalist groups); counts of Jain, Shinto, Sikh, Tao and National Spiritualist Association congregations, and counts of congregations and adherents from Bahá'ís, three Buddhist groupings, four Hindu groupings, four Jewish groupings, Muslims and Zoroastrians. The 236 groups reported a total of 344,894 congregations with 150,686,156 adherents, comprising 48.8 percent of the total U.S. population of 308,745,538 in 2010.

The Religion and State Project, Round 2

The Religion and State (RAS) project is a university-based project located at Bar Ilan University in Ramat Gan, Israel. Its goal is to create a set of measures that systematically gauge the intersection between government and religion. The RAS dataset measures the extent of government involvement in religion (GIR), or the lack thereof, for 175 states on a yearly basis between 1990 and 2008. This constitutes all countries with populations of 250,000 or more, as well as a sampling of smaller states.

Religious Congregations and Membership Study, 2000 (Counties File)

This study, designed and completed by the Association of Statisticians of American Religious Bodies (ASARB), represents statistics for 149 religious bodies on the number of congregations within each county of the United States. Where available, also included are actual membership (as defined by the religious body) and total adherents figures. Participants included 149 Christian denominations, associations, or communions (including Latter-day Saints and Unitarian/Universalist groups); two specially defined groups of independent Christian churches; Jewish and Islamic totals; and counts of temples for six Eastern religions. It is important to understand the methodology producing these data and its limitations. While these data contain membership data for many religious groups in the United States, including most of the larger groups, they do not include every group. It is recommended that users read the notes below. Users may also want to refer to a paper by Roger Finke and Christopher P. Scheitle that explains the "adjusted" adherence rates included in the file.

General Social Survey 2014 Cross-Section and Panel Combined

The General Social Surveys (GSS) have been conducted by the National Opinion Research Center (NORC) annually since 1972, except for the years 1979, 1981, and 1992 (a supplement was added in 1992), and biennially beginning in 1994. The GSS are designed to be part of a program of social indicator research, replicating questionnaire items and wording in order to facilitate time-trend studies. This data file has all cases and variables asked on the 2014 GSS. There are a total of 3,842 cases in the data set but their initial sampling years vary because the GSS now contains panel cases. Sampling years can be identified with the variable SAMPTYPE.

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.

National Congregations Study, Cumulative Dataset (1998, 2006-2007, and 2012), Version 2

The National Congregations Study (NCS) dataset "fills a void in the sociological study of congregations by providing, for the first time, data that can be used to draw a nationally aggregate picture of congregations" (Chaves et al. 1999, p.460). Thanks to innovations in sampling techniques, the NCS data is the first nationally representative sample of American congregations. In 2006-07, a panel component was added to the NCS. In addition to the new cross-section of congregations generated in conjunction with the 2006 General Social Survey (GSS), a stratified random sample was drawn from congregations who participated in the 1998 NCS. The 2006-07 NCS sample, then, includes a subset of cases that were also interviewed in 1998. The 2012 NCS includes an oversample of Hispanic congregations. The NCS Panel Dataset is also available from the ARDA.

General Social Survey, 2016

The General Social Surveys (GSS) have been conducted by the National Opinion Research Center (NORC) annually since 1972, except for the years 1979, 1981, and 1992 (a supplement was added in 1992), and biennially beginning in 1994. The GSS are designed to be part of a program of social indicator research, replicating questionnaire items and wording in order to facilitate time-trend studies. This data file has all cases and variables asked on the 2016 GSS.
