Data Analysis: 20 Years of U.S. Church Change (2000–2020)
This report analyzes congregation count data from the U.S. Religion Census (RCMS), conducted approximately every 10 years and published through The Association of Religion Data Archives (ARDA). The census covers all reporting religious bodies across all 50 states and D.C. Population figures come from the U.S. Census Bureau decennial census.
Key National Finding
The U.S. saw a net decline of approximately 15,600 congregations between 2000 and 2020 — from ~384,000 to ~368,000. The rate of closure has accelerated: losses from 2010–2020 outpaced 2000–2010 in most states.
Source: Calculated from RCMS congregation counts (2000, 2010, 2020 census years) as published by The ARDA.
Per Capita Perspective
Raw congregation counts can be misleading. A state that "grew" in total congregations may have actually fallen behind its population growth. When measured as congregations per 10,000 people, the picture shifts:
Congregations Per 10,000 People (2020)
National average: approximately 11.2 congregations per 10,000 people. In 1900, the ratio was 27 per 10,000. States like Mississippi (19.1), North Dakota (18.0), and Kansas (13.2) remain above average. But high-population states like California (6.3), New York (6.4), and New Jersey (5.9) are well below.

Regional Patterns
Regional congregation counts from RCMS via ARDA. Denominational context from Lifeway Research and denominational annual reports.
Northeast: Steepest Decline
New York (-2,170), Pennsylvania (-2,140), and Massachusetts (-790) experienced the heaviest losses. Mainline Protestant decline and Catholic parish consolidations drive this. The Northeast also has the lowest per-capita congregation rates in the nation.
Midwest: Steady Erosion
Ohio (-1,530), Illinois (-1,430), Michigan (-1,140). Rural depopulation compounds the effect — as small towns lose residents, their churches close with them. States like North Dakota and Iowa still have among the highest per-capita church rates, reflecting deep historical roots.
South: Mixed Results
Texas (+2,400) and Florida (+1,400) grew, but Alabama (-632) and Mississippi (-530) declined. The Southern Baptist Convention has lost congregations every year since 2017. (Lifeway Research)
West: Population-Driven Growth
Arizona (+929), Utah (+610), Colorado (+515), Idaho (+270) all grew, tracking population booms. But per capita, western states often have fewer churches per person than the South or Midwest. (RCMS via ARDA; 2020 Census)
The Acceleration Problem
In most declining states, 2010–2020 was worse than 2000–2010. Contributing factors:
- "Nones" surge: Americans identifying as religiously unaffiliated rose from 16% (2007) to 29% (2023). Among 18–29-year-olds: 44%. (Pew Research Center, 2024)
- "Silver Tsunami": Baby boomers aging out of church leadership and financial giving, leaving many small congregations unsustainable. (Boston University, 2025)
- Pastoral shortage: Small and rural churches increasingly cannot attract or afford a full-time pastor. (Lifeway Research)
- COVID-19 aftermath: The 2020 census captured the start of pandemic disruption. Many churches that went virtual never returned to in-person viability. (Axios, 2025)
- United Methodist Church split (2023–24): Thousands of congregations disaffiliated over theological disagreements; some closed entirely rather than join a new body. (Axios)
What This Means Going Forward
Lifeway Research projected that 15,000 churches could close in 2025 alone — triple the annual rate from a decade earlier. (Axios, Oct 2025; Lifeway Research, Jan 2026)
The National Council of Churches estimates 100,000 total closures over the coming years — roughly 1 in 4 existing congregations. (MinistryWatch investigation)
For rural communities, each closure is not just spiritual but social: a meeting place, a food pantry, a funeral home of last resort. (Chronicle of Philanthropy)
Idaho: A Bright Spot
Idaho grew consistently across both decades: +160 (2000-10) and +110 (2010-20) for +270 total. At 12.8 congregations per 10,000 people, Idaho is above the national average — reflecting both population growth and active church planting across the Treasure Valley.
