More churches than ever, yet fewer members per capita
From 1952 to 2020, the number of U.S. congregations nearly doubled (182,856 → 356,642), while the median congregation size collapsed by 52% (137 → 65 attendees). America is fragmenting into a landscape of micro-churches.
The increase in congregation count is partly methodological—ASARB's improved counting of independent, nondenominational, and non-Christian groups. But the underlying trend is real: American religion is fragmenting. We have more religious organizations serving fewer people per capita. The "long tail" of tiny congregations is growing, while a small number of megachurches absorb the majority of active participants. This creates a sustainability crisis: the median church of 65 cannot afford a full-time pastor, professional staff, or building maintenance. The future likely holds significant congregational closures as small churches lose their aging members.
