In the United States, the number of Muslims is expected to increase from 2.6 million in 2010 to 6.2 million by 2030, in large part because of immigration and higher-than-average fertility among Muslims. The Muslim share of the U.S. population (adults and children) is projected to grow from 0.8% in 2010 to 1.7% in 2030, making Muslims roughly as numerous as Jews or Episcopalians are in the United States today.
Pew Research reports, “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 country other than Russia and France.”
Once very small, the Muslim population of the US increased greatly in the 20th century, with much of the growth driven by rising immigration and conversion, and a comparatively high birth rate.In 2005, more people from Islamic countries became legal permanent United States residents — nearly 96,000 — than in any year in the previous two decades.
American Muslims come from various backgrounds, and are one of the most racially diverse religious group in the United States according to a 2009 Gallup poll.Native-born American Muslims are mainly African Americans who make up 24% of the total Muslim population. Many of these have converted to Islam during the last seventy years. Conversion to Islam in prison, and in large urban areas has also contributed to its growth over the years. South Asian immigrants (from India, Pakistan and Bangladesh) make up 26% of the Muslim population, and Arabs make up 26% of the population. The remaining 24% percent is from other groups.
