New Study Estimates Global Muslim Population at 1.57 Billion

Nearly a Quarter of World Population is Muslim

WASHINGTON, Oct. 7 /PRNewswire-USNewswire/ -- 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:

-- While Muslims are found on all five inhabited continents, more than
60%
of the global Muslim population is in Asia and about 20% is in the
Middle East and North Africa.
-- The Middle East-North Africa region has the highest percentage of
Muslim-majority countries. More than half of the 20 countries and
territories in that region have populations that are approximately 95%
Muslim or greater.
-- More than 300 million Muslims, or one-fifth of the world's Muslim
population, live in countries where Islam is not the majority
religion.
These minority Muslim populations are often quite large. India, for
example, has the third-largest population of Muslims worldwide. China
has more Muslims than Syria, while Russia is home to more Muslims than
Jordan and Libya combined.

-- Of the total Muslim population, 10-13% are Shia Muslims and 87-90% are
Sunni Muslims. Most Shias (between 68% and 80%) live in just four
countries: Iran, Pakistan, India and Iraq.

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
(http://pewforum.org/docs/?DocID=450).

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.
