If the current demographic trends hold, Muslims could become the second-largest religious group in the United States by 2050, surpassing Jews, who currently hold the number two spot, according to the Pew Research Center.

PF_15.04.02_ProjectionsOverview_usReligComposition_310pxU.S. Muslims have the highest fertility rate and the youngest median age of any major religious group in the country, according to Michael Lipka of the Pew Research Center, which is helping to fuel this growth.

The number of people who identify as Jewish is expected to decline from 1.8 percent in 2010 to 1.4 percent in 2050.

In 2010, the median age of American Jews was 41 years old, while the media age for Muslims was 24 — a 17-year age gap.

Also, on average, Jews have 1.9 children per woman while that number is 2.8 for U.S. Muslims, according to Pew.

In a 2013 survey, Pew found that more than that 22 percent of American Jewish adults considered themselves to be atheist, agnostic or nothing in particular, but still identified as Jewish.

Pew does not include these people in the Jewish population. If the projected numbers were to include these “cultural” or “ethnic” Jews, it’s possible this more broadly defined Jewish population might still outnumber Muslims in 2050.

Whatever the changes, overall, the United States is expected to remain an overwhelmingly Christian nation.

In 2010, more than three-fourths of Americans — 78.3 percent — identified as Christian.

However, a growing number of Americans consider themselves to be religiously unaffiliated and, by 2050, the number of people who consider themselves to be Christians is expected to drop to 66.4 percent.

All three religions — Christianity, Islam and Judaism — trace their common origin to the patriarch Abraham and believe in a single God.
