Yearbook of International Religious Demography
2014 (Brill, 2014)
Co-edited by Brian Grim (Religious Freedom and Business Foundation), Todd Johnson (Center for the Study of Global Christianity), Vegard Skirbekk (International Institute for Applied Systems Analysis), and Gina Zurlo (Center for the Study of Global Christianity), the Yearbook of International Demography provides an annual snapshot of the state of religious statistics around the world. Visit the Brill page for details, including a table of contents.
Some key findings:
- In 2013, Asia had five times as many atheists and agnostics than Europe.
- Muslims are expected to grow twice as fast from 2013 to 2030 in Africa as they are in Europe.
- Protestantism and Catholicism are reported as likely independent predictors of fertility rates in Nigeria, with women from those traditions reporting lower rates of children ever born. Muslim women were more likely to report high fertility, early marriage and childbirth, and non-use of any modern contraceptives.
- Christians in Europe are relatively old, with a median age of 41.7 years; among 25-44 year olds, 72% are Christian, compared to 84% of the 65+ population. Muslim age-relation in Europe goes the other way, since most Muslims are fairly recent migrants.
- In Mongolia, both Buddhists and non-religious women experienced fertility decline in the early 1990s and 2000s; however, in the mid-2000s Buddhist women reached a lower level of fertility than those from non-religious households and have fewer children.
Co-authored by Todd Johnson and Brian Grim (Pew Research Center Religion & Public Life Project), this unique introduction to international religious demography outlines the challenges in interpreting data on religious adherence, and presents a contemporary portrait of global religious belief.

- Offers the first comprehensive overview of the field of international religious demography; detailing what we know about religious adherents around the world, and how we know it
- Examines religious freedom and diversity, including agnostics and atheists, on a global scale, highlighting trends over the past 100 years and projecting estimates for the year 2050
- Outlines the issues and challenges related to definitions, taxonomies, sources, analyses, and other techniques in interpreting data on religious adherence
- Considers data from religious communities, censuses, surveys, and scholarly research, along with several in-depth case studies on the global Muslim population, religion in China, and the religious demography of recently created Sudan and South Sudan
- Argues against the belief that the twentieth-century was a "secular" period by putting forward new evidence to the contrary
- Provides resources for measuring both qualitatively and quantitatively important data on the world's religious situation in the twenty-first century
Designed for both the casual user and research scholar, the World Christian Database (WCD) is an online database containing comprehensive demographic statistics on global Christianity. Over 400 categories of information including religious adherents, Christian traditions and missions trends are available at the province, country, people group, language and city levels for the entire world. The full-time staff at The Center for the Study of Global Christianity is dedicated to updating and maintaining the WCD. New information from thousands of sources is reviewed on a weekly basis to continually refine and improve the WCD.

World Religion Database (Brill, 2008)
The World Religion Database (WRD), edited by Todd Johnson and Brian Grim, contains detailed statistics on religious affiliation for every country in the world. It is the major source to render a definitive picture of international religious demography. The WRD provides both current and historical data, as well as sophisticated forecasts of future developments. For each of the world’s religions, best estimates at multiple dates for the period 1900 to 2050 are given. The WRD also offers access to the sources which underlie the figures in the database, such as censuses and surveys. Through an interactive feedback mechanism users can leave comments on sources or methodology related to any figure reported in the WRD. The WRD is constantly updated with new sets of data as they become available, such as estimates of religious affiliation at the province level and religious freedom information for all countries in the world. No other database available today is as comprehensive. Click here for more information, or to access the World Religion Database.

Atlas of Global Christianity (Edinburgh University Press, 2009)
The Atlas of Global Christianity is a thorough visual reference of the changing status of global Christianity over the 100 years since the epoch-making ‘Edinburgh 1910’ World Missionary Conference. It is the first scholarly atlas to depict the twentieth-century shift of Christianity to the Global South. It is also the first to map Christian affiliation at the provincial level.
First published in 1982, the World Christian Encyclopedia (WCE) immediately took its place as the authoritative, standard work in its field. The second edition’s oversized 1,700 pages represent the most extensive survey of Christianity, and of religion in general, ever attempted. The heart of the WCE is a series of 238 chapters on the status of religion and of Christianity in every country in the world. Statistical tables show, in great detail, the religious breakdown of the population and the Christian denominations of every country. The second edition updated and extended this analysis to include the status of Christianity in every language, people, city and province of the world.
A 952-page companion volume to the World Christian Encyclopedia, World Christian Trends (WCT) includes a first-ever empirical survey of Christian martyrdom, historical trends, future projections and finance. Included in this volume are a variety of charts, tables, and lists.
