Stats: More Muslims & Roman Catholics?

More Catholics, Muslims, fewer Presbyterians

Despite conversions and a lower fertility rate among white Catholics, the expected growth of Hispanic Catholics could lead to a historic shift in American religion, according to Skirbekk, Goujon and Kaufmann.

In their study largely based on General Social Survey findings, census immigration statistics and Pew data, the researchers state the rise among Hispanics "will power the growth of Catholics as a whole, who will surpass Protestants by mid-century within the nation's youngest age groups."
