Muslims will be the second-largest religious group in America by 2040 because of higher birth rates, according to a new study.

The data published last week by the Pew Research Center shows that Islam will surpass Judaism as the second biggest religion in the country, behind Christianity, within two decades. According to Pew, the Muslim population will more than double in that time period, from 3.45 million in 2017 (1.1 percent of the total population) to 8.09 million in 2050 (2.1 percent of the total population).

As that increase takes place, America’s Muslim population is set to springboard above its Jewish population by 2040.
