Although the US Census Bureau does not have the exact data about Muslims living in America. The PEW research centre has come up with a research that by 2040, Muslims will replace Jews as the nation’s second-largest religious group after Christians.
The reason for US Census Bureau of not having data of Muslim population in the country is because it does not ask questions about religion.
Muslims in the US are not as numerous as the number of Americans who identify as Jewish by religion, according to Pew research estimate. At the same time, PEW projections suggest that the US Muslim population will grow much faster than the country’s Jewish population.
By 2040, Muslims will replace Jews as the nation’s second-largest religious group after Christians. And by 2050, the U.S. Muslim population is projected to reach 8.1 million, or 2.1 per cent of the nation’s total population — nearly twice the share of today.
The latest estimate combines information from PEW research 2017 survey of U.S. Muslims, which reported on the prevalence of Muslims among immigrants and other demographic groups with official Census Bureau data on the number of people in these groups.
