MUSLIM POPULATION ON EARTH AND ITS GROWTH PROJECTIONS:

The world’s Muslim population is expected to increase by about 35 per cent in the next 20 years, rising from 1.6 billion in 2010 to 2.2 billion by 2030, according to population projections given in a January 27, 2011 report of the Washington DC-based non-partisan think tank “Pew Research Center’s Forum on Religion & Public Life.”
Globally, the Muslim population is forecast to grow at about twice the rate of the non-Muslim population over the next two decades - an average annual growth rate of 1.5 per cent for Muslims, compared with 0.7 per cent for non-Muslims. If current trends continue, Muslims will make up 26.4 per cent of the world’s total projected population of 8.3 billion in 2030, up from 23.4 per cent of the estimated 2010 world population of 6.9 billion.
While the global Muslim population is expected to grow at a faster rate than the non-Muslim population, the Muslim population nevertheless is expected to grow at a slower pace in the next two decades 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 per cent, compared with the projected rate of 1.5 per cent for the period from 2010 to 2030.
The Pew Research Center’s Forum on Religion & Public Life had stated in its January 2011 report: “If current trends continue, however, 79 countries will have a million or more Muslim inhabitants in 2030, up from 72 countries today.”
It had maintained: “But Pakistan is expected to surpass Indonesia as the country with the single largest Muslim population. The portion of the world’s Muslims living in sub-Saharan Africa is projected to rise; in 20 years, for example, more Muslims are likely to live in Nigeria than in Egypt. Muslims will remain relatively small minorities in Europe and the Americas, but they are expected to constitute a growing share of the total population in these regions.”
The Pew Research Center’s Forum on Religion & Public Life had further stated:
In the United States, the population projections show the number of Muslims more than doubling over the next two decades, rising from 2.6 million in 2010 to 6.2 million in 2030, in large part because of immigration and higher-than-average fertility among Muslims.
The Muslim share of the American population (adults and children) is projected to grow from 0.8 per cent in 2010 to 1.7 per cent in 2030, making Muslims roughly as numerous as Jews or Episcopalians are in the United States today. Although several European countries will have substantially higher percentages of Muslims, the United States is projected to have a larger number of Muslims by 2030 than any European countries other than Russia and France.
In Europe as a whole, the Muslim share of the population is expected to grow by nearly one-third over the next 20 years, rising from 6 per cent of the region’s inhabitants in 2010 to 8 per cent in 2030.
In absolute numbers, Europe’s Muslim population is projected to grow from 44.1 million in 2010 to 58.2 million in 2030. The greatest increases - driven primarily by continued migration - are likely to occur in Western and Northern Europe, where Muslims will be approaching double-digit percentages of the population in several countries. In the United Kingdom, for example, Muslims are expected to comprise 8.2 per cent of the population in 2030, up from an estimated 4.6 per cent today. In Austria, Muslims are projected to reach 9.3 per cent of the population in 2030, up from 5.7 per cent today; in Sweden, 9.9 per cent (up from 4.9 per cent today); in Belgium, 10.2 per cent (up from 6 per cent today); and in France, 10.3 per cent (up from 7.5 per cent today).
