Washington, DC - A new, comprehensive demographic study of more than 200 countries finds that there are 1.57 billion Muslims of all ages living in the world today, representing 23% of an estimated 2009 world population of 6.8 billion. Released today by the Pew Research Center's Forum on Religion & Public Life, Mapping the Global Muslim Population offers the most up-to-date and fully sourced estimates of the size and distribution of the worldwide Muslim population, including sectarian identity.
Key findings include:
Previously published estimates of the size of the global Muslim population have ranged widely, from 1 billion to 1.8 billion. The new study is based on the best available data for 232 countries and territories. Pew Forum researchers, in consultation with nearly 50 demographers and social scientists at universities and research centers around the world, analyzed about 1,500 sources, including census reports, demographic studies and general population surveys, to arrive at these figures - the largest project of its kind to date.
The report includes an executive summary, maps and charts illustrating Muslims' geographic distribution, explanations of the study's methodologies and a list of data sources by country. The report is available online.
These findings on the world Muslim population lay the foundation for a forthcoming study by the Pew Forum, scheduled to be released in 2010, that will estimate growth rates among Muslim populations worldwide and project Muslim populations into the future. The Pew Forum plans to undertake similar demographic studies of the major global religions in the future.
