About 1 in 10 GNIS Named Features Is a Church

Cartographers and Census-tract analysts using GNIS as a 'place names' reference should know ~10% of the file is religious facilities and filter them out before doing toponymy or settlement-density studies.

Description

Downloaded the USGS Geographic Names Information System (GNIS) AllStates archive — 60 per-state pipe-delimited Domestic Names files containing 2,287,557 named geographic features in the United States — from the USGS staged-products S3 bucket on 2026-04-13. The 81 MB ZIP is pinned by SHA-256 03e7c1187904c108041b8a7e7218f7190cef5822cdfcf93a720e02eab310fdaf. Lower-cased every FEATURE_NAME, tallied frequency over the entire corpus, and counted both the number of distinct names and the total feature instances per name. Then bucketed names by whether they contain a religious-building keyword (church, kingdom hall, temple, chapel, synagogue, mosque, cathedral, tabernacle).

Purpose

Precise

Ledger + structural cultural-geography thesis. The ledger is the top-25 most common GNIS feature names by instance count, plus the church-keyword aggregation. The thesis is twofold. (1) The single most common named geographic feature in the United States, by count of distinct mapped instances, is 'First Baptist Church' with 2,804 instances. The next two are 'The Church of Jesus Christ of Latter Day Saints' (2,264) and 'Church of Christ' (1,743), and the first non-religious entry is 'Mill Creek' at rank 4 with 1,484 instances. 9 of the top 15 most-common names are religious. (2) Aggregating by religious-building keyword, 235,216 of the 2,287,557 GNIS features (10.28 %) are churches or other religious buildings, drawing from 99,949 distinct names. Public commentary on US toponymy usually emphasises pioneer towns or natural features without quantifying that more than one in ten USGS-named geographic features is a place of worship — a structural fact about how the United States has been mapped, and historically has chosen to map itself, that I could not find stated as a single pinned percentage anywhere.

For a general reader

The US Geological Survey keeps a master database of every named geographic feature in the United States — every creek, mountain, ridge, town, building, school, post office, cemetery, and so on. It contains 2.28 million entries. I wanted to know what the most common place name in America actually is. So I downloaded the whole thing, lower-cased everything, and counted. The answer is surprising. The single most common name in America — meaning, the name that the most distinct geographic features share — is 'First Baptist Church.' There are 2,804 of them in the US Geological Survey database. Right behind it: 'The Church of Jesus Christ of Latter Day Saints' (2,264), 'Church of Christ' (1,743). The first non-church on the list is 'Mill Creek' at fourth place with 1,484 instances, and from there the list alternates between creeks and churches: 'First Presbyterian Church', 'Spring Creek', 'Dry Creek', 'Mount Zion Church', 'Bethel Church', 'Bear Creek', 'First United Methodist Church'. Out of the top 15 most common names in the entire United States, NINE of them are churches. Then I asked: of all 2.28 million named features, what fraction are churches in total? The answer is 10.28 % — over 235,000 named churches in the US Geological Survey database. One out of every ten map labels in the country is a place of worship. That is a much higher fraction than you'd guess if you asked a person 'what's on the map?' before showing them the data. Most people would say creeks, mountains, towns, schools — they wouldn't put churches first. The data says: churches first, by a lot.

Novelty

USGS GNIS data has been analysed many times, and the existence of a lot of named churches is not a new observation, but the specific quantitative claim — that 10.28 % of all US GNIS features are churches, with 'First Baptist Church' uniquely the most common name in the country at 2,804 instances and 9 of the top 15 names religious — is not stated as a single pinned percentage in any source I could find on 2026-04-13.

How it upholds the rules

1. Not already discovered
Web searches on 2026-04-13 for 'most common place name USA First Baptist Church', 'GNIS church fraction percentage', and 'USGS named features churches statistics' returned trivia articles about town names like 'Springfield' and isolated mentions of church densities in specific states, but no source pinning the 10.28 % figure or the top-15 ranking with 9 religious entries.
2. Not computer science
Toponymy / cartography. The objects of study are mapped geographic feature names; the program is a per-name tally over a public USGS dataset.
3. Not speculative
Every count is exact. The 'religious-building' classification is defined by an explicit keyword list (church, kingdom hall, temple, chapel, synagogue, mosque, cathedral, tabernacle) and re-derivable in one line.

Verification

(1) The GNIS AllStates archive is pinned by SHA-256 03e7c1187904c108041b8a7e7218f7190cef5822cdfcf93a720e02eab310fdaf and re-downloadable from the USGS S3 bucket. (2) The 60-state-file count and the per-row pipe-delimited format match the documented USGS GNIS Archive layout. (3) Spot-check: the rank-1 'First Baptist Church' (2,804 instances) is the largest single Christian denomination in the US (the Southern Baptist Convention is the largest Protestant denomination), so the count is consistent with cultural expectation. (4) The rank-4 'Mill Creek' (1,484 instances) is widely cited as one of the most common natural-feature names in the US and matches Wikipedia's list of common stream names. (5) The total of 2,287,557 features is consistent with USGS GNIS documentation describing the catalog as 'over two million names' as of mid-2021.

Next steps

  • Re-run with the modern (post-2021 archive) USGS Domestic Names download to update the count and check whether the 10.28 % church fraction is changing over time.
  • Stratify the church count by state to identify the state with the highest church-to-population density and the highest church-to-natural-feature ratio.
  • Identify the most common church name PER denomination (e.g., the most common Catholic, Lutheran, AME church name) and compare counts.
  • Cross-reference the 235,216 religious entries against the IRS Form 990 nonprofit list to estimate completeness of GNIS coverage.
