New Pew Forum Report Projects Global Muslim Population to Increase Approximately 35% in Next 20 Years

But Rate of Growth Expected at Slower Pace than Past Two Decades

WASHINGTON, January 27, 2011 - The world's Muslim population is expected to increase by about 35% in the
next 20 years, rising from 1.6 billion in 2010 to 2.2 billion by 2030,
according to a new, comprehensive report released today by the Pew Research
Center's Forum on Religion & Public Life (www.pewforum.org/) on the
size, distribution and growth of the Muslim population. The study is part of
the Pew-Templeton Global Religious Futures project, an effort funded by The
Pew Charitable Trusts (www.pewtrusts.org/) and the John Templeton
Foundation (www.templeton.org/) to analyze religious change and its
impact on societies around the world.

Over the next two decades, the worldwide Muslim population is forecast to
grow at about twice the rate of the non-Muslim population - an average annual
growth rate of 1.5% for Muslims compared with 0.7% for non-Muslims. If
current trends continue, Muslims will make up 26.4% of the world's total
projected population of 8.3 billion in 2030, up from 23.4% of the estimated
2010 world population of 6.9 billion.

However, while the global Muslim population is predicted to grow at a
faster rate than the non-Muslim population, it is also expected to grow at a
slower pace in the next 20 years than it did in the previous two decades.
From 1990 to 2010, the global Muslim population increased at an average
annual rate of 2.2%; for the period from 2010 to 2030, the rate of growth is
projected to be 1.5%.

These are among the key findings of The Future of the Global Muslim
Population, which seeks to provide up-to-date estimates of the number of
Muslims around the world in 2010 and to project the growth of the Muslim
population from 2010 to 2030.

The full report, which includes an executive summary, interactive maps
and sortable data tables, is available on the Pew Forum's website
(pewforum.org/The-Future-of-the-Global-Muslim-Population.aspx).
