There was email discussion among few participants whether Islam is the fastest growing religion in USA. I thought let me do some research. I found some interesting articles on all religions including non religious groups. I am sharing them below with affiliates.
2015 PEW SURVEY:
“The study, which Pew says is the first of its kind, bases its projections on the age of populations, fertility and mortality rates, as well as migration and conversion patterns. Simply put, Muslims are having larger families, retaining more members (conversions are illegal in some Muslim nations) and are younger than adherents of other faiths. More than 1 in 3 Muslims is younger than 15.”
“Atheists, agnostics and religiously unaffiliated people will increase in the United States (from 16% to 26%) but decline as a share of the total worldwide population.
— Also in the United States, Christians will drop from 78% to 66% of population. Muslims will surpass Jews as the largest non-Christian religion in the U.S.
— Sub-Saharan African will be home to 40% of the Christian population and Nigeria have more Christians than any other country except for the United States and Brazil.
— India will have the largest Muslim population in the world, passing Indonesia, but Hindus will retain a majority.
— More than 10% of Europeans will be Muslim, while the number of Christians in Europe will drop by 100 million.
— Hinduism (1.4 billion adherents) and Judaism (16 million) will increase, while Buddhists will be about the same size as in 2010 (5.2 million).”
2010 US Religions Census;
“Data released Tuesday from the 2010 U.S. Religion Census shows Islam was the fastest growing religion in America in the last 10 years, with 2.6 million living in the U.S. today, up from 1 million in 2000.
Immigration from parts of the Muslim world and a small rise in conversions are the driving force behind the growth, researchers said. Jones also speculated that the burst of anti-Islam sentiment after the 9/11 attacks could have done more to grow the religion’s presence in the U.S. than slow it. Those on the fence about converting to Islam may have decided to do so on principle.”
“The survey also indicates that the group that had the greatest net gain was the unaffiliated. More than 16 percent of American adults say they are not part of any organized faith, which makes the unaffiliated the country’s fourth largest “religious group.”
Immigration continues to influence American religion greatly, the survey found. The majority of immigrants are Christian, and almost half are Catholic. Muslims rival Mormons for having the largest families. And Hindus are the best-educated and among the richest religious groups, the survey found.
“I think politicians will be looking at this survey to see what groups they ought to target,” Professor Prothero said. “If the Hindu population is negligible, they won’t have to worry about it. But if it is wealthy, then they may have to pay attention.”
Experts said the wide-ranging variety of religious affiliation could set the stage for further conflicts over morality or politics, or new alliances on certain issues, as religious people have done on climate change or Jews and Hindus have done over relations between the United States, Israel and India.
“It sets up the potential for big arguments,” Mr. Green said, “but also for the possibility of all sorts of creative synthesis. Diversity cuts both ways.”
Guinness Book Of World Record;
“However, according to others, including the 2003 edition of the Guinness Book of World Records, Islam is the world’s fastest-growing religion by number of conversions each year: “Although the religion began in Arabia, by 2002 80% of all believers in Islam lived outside the Arab world.”
