Muslim Population in the U.S.: A 250-Year History
From the low thousands in the thirteen colonies to roughly 4.5 million today — the numbers behind the story.
How to read these numbers
Full methods →The U.S. Census does not ask about religion. No figure on this page is an official government headcount of Muslims. Charts use epistemic labels so a historical estimate is never confused with a survey, and a projection is never confused with a present count.
- Historical estimate
Scholarship on incomplete records; often a range.
- Survey (verified)
Named research organization with published methodology.
- Modeled estimate
Demographers’ synthesis; may differ from a survey headline.
- Projected
Future scenario under stated assumptions — not a present fact.
Most citable headline for general use: Pew’s 2017 estimate of roughly 3.45 million Muslims of all ages (about 1.1% of the U.S. population). Later modeled figures (e.g. ~4.5 million) are labeled as modeled, not substituted for that survey point.
The population journey, 1776–2050
Log scale — each gridline is 10× the one below, so two centuries of small numbers stay visible.
Muslims made up about 1.1% of the total U.S. population. Roughly 58% were foreign-born, and the community was among the most racially and ethnically diverse religious groups in the country. This is the most citable headline figure.
Bands mark the spread of historical estimates described in each era's note; single points are the figure named there.

Institutions kept pace
The number of mosques in the United States nearly tripled in a generation.
A community of many Americas
The most striking fact about American Muslims is not their number — it is their range. No other major U.S. faith community looks like the whole country at once the way this one does.
- White (~30%) — 30
- Asian (~30%) — 30
- Black (~20%) — 20
- Hispanic (~11%) — 11
- Other / multiracial (~8%; 9 cells to total 100) — 9
Each square is one of every 100 U.S. Muslim adults. Pew reports roughly 30% White, 30% Asian, 20% Black, 11% Hispanic, and 8% another race or more than one race (short-read, June 2025). Figures are approximate and sum to ~99%; the waffle uses 9 residual cells so the grid totals 100 — a display rounding, labeled as such.
Pew Research Center — How U.S. Muslims compare with other Americans (2025)
In ISPU's national polling, American Muslims are the only faith community surveyed with no majority racial group: roughly a quarter Black and a quarter white, with large Asian, Arab, mixed-race, and Hispanic shares. Pew's 2025 comparison finds the same pattern — about 30% white, 30% Asian, 20% Black, and 11% Hispanic — where most other U.S. religious groups are predominantly one race. Pew has called Muslims among the most racially diverse religious groups in the United States.
ISPU polling finds 35% of Muslim households earn under $30,000 — the highest share of any faith group surveyed — while roughly a quarter earn over $100,000, on par with most groups. The community spans corner-store owners and refugees, physicians and engineers. That spread is not evenly shared: white and Asian Muslim households are far more likely to be high-income than Black Muslim households — a real internal inequality the survey data makes visible.
Pew finds U.S. Muslims are about as likely as Americans overall to hold a college degree, with high representation in medicine, engineering, and the sciences — consistent with a community built from both long-rooted American families and skilled post-1965 immigration.
What these charts cannot yet show
- No official Census religion question — every total is estimate, survey, or model.
- Race categories differ across organizations; MENA respondents may be coded “white” in one series and separately in another.
- Historical bands for the founding and antebellum eras rest on incomplete plantation and legal records.
- State- and metro-level Muslim population series are not yet published here with the same epistemic care.
- Mosque counts measure institutions, not attendance or belief.
