Dramatic demographic expansion is what makes a religion a world religion

Evidence

To put those numbers into perspective, the total number of Christians globally in 2015 was 2.3 billion. The total number of Muslims in 2015 was 1.8 billion, while the religiously unaffiliated comprised 1.2 billion of the world population (Pew Research Center 2017, 8). Thus, the net impact of religious switching on demographic changes is dwarfed by the larger population growth factors of fertility rates and age distribution. — Margaret Hodson, Baby Jihad, 34 (#corroborates, via linked claim)

Nevertheless, it is far from clear to me that secular societies will win the race for cultural longevity. On one hand, we have the powerful forces of secularization gaining ground in some places—more economic prosperity, greater existential security, strong secular institutions, and mass exposure to higher learning, science, and analytic thinking. This means that people in these societies are on the verge of moving beyond prosocial religions. But prosocial religions have one crucial advantage over secular ones—the demographic windfall of more children. And that religious advantage is the secularists’ Achilles’ heel—in fact, the most secularized societies are having the fewest children. This means that what prosocial religious groups lose against the forces of secularization, they gain in reproduction. — Norenzayan, Ara, Big gods - how religion transformed…, 630 (#corroborates, via linked claim)
