A clear, source-based tracker — not a guess. About 5.5 million Muslims live in the U.S. today, roughly 1.6% of the population. They live in every state, but the largest communities are concentrated in a handful of metro areas: New York, Chicago, Detroit, Los Angeles, Houston and North Jersey.
All ages, Sept. 2026 Pew portrait. Up from 2.4M in 2007 — more than double in 19 years.
1% of adults in Pew's 2023–24 Religious Landscape Study; 1.6% when children are included.
4,453,908 counted via mosques / congregations — 1.34% of the U.S. in 2020. Different method, lower total.
In 2020, up 31% from 2,106 in 2010 and up from ~1,209 in 2000. ISPU U.S. Mosque Survey.
Built like the choropleth maps statistical agencies publish: real state outlines at full geographic detail, classed shading in six steps, and every state labeled on the map. Turn on the Heat map overlay filter below the shading controls to blend a green → yellow → red glow over the same map — green for lower concentration, yellow for medium, red for the hottest spots — so clusters around New York, Chicago, Detroit, Los Angeles and Houston mesh together visually. Keep it on top of any shading mode and re-weight it by population, % of state, or trend growth. Hover any state for its headline figure, and read the full readout — rank, estimated population, % of state, mosques, trend, and how it compares with the national share — in the panel under the map. Small Northeastern states are unreadable at national scale on any map, so use the Northeast view button (or scroll / pinch to zoom and drag to pan). Keep zooming and the map keeps going: county outlines and names fade in, the researched hub counties are highlighted, city pins mark the big metros, and at street level the shading fades back so roads and street names show through — try the two street-level view buttons. On a phone, the state picker and the Top 5 chips do the same job as hovering.
How this map is drawn: published U.S. state boundary geometry at full resolution over a grayscale base map; classed (stepped) shading, not a smooth gradient, so each color means an exact range in the legend; state labels thin out at national zoom and fill in as you zoom, the same convention reference atlases use. County boundaries (all ~3,100 counties, standard public county geometry) fade in from regional zoom with county names at city zoom; the 15 researched hub counties are outlined in dark teal — hover one for its readout. Keep zooming and the shading fades so the base map's roads and street names take over. When the heat map filter is on, its glow also fades at street level so roads stay readable underneath. © OpenStreetMap contributors, Map Data Legal Notices

Pew estimates over time, plus the 2050 projection. Growth is driven mainly by immigration and a younger age profile / higher fertility — the same drivers Pew models for other groups.
Pew projects Muslims could pass Jews as the second-largest religious group by around 2040 if current fertility, age and immigration patterns hold. Projections are scenarios, not certainties — they shift with immigration policy.
Pew Religious Landscape Study 2023–24, adults
35% of Muslim adults are 18–29, vs. 14% of Christian adults. 42% are 30–49, 13% are 50–64, 8% are 65+. That younger median age is a major reason the population grows faster than the U.S. average even without immigration.
Mosque growth mirrors population growth1,209 mosques (2000) → 2,106 (2010) → 2,769 (2020). New mosques are increasingly suburban and purpose-built (37% in 2020, up from 30% in 2010); mosques in small towns fell from 20% to 6% of the total.

* Trend column: ISPU U.S. Mosque Survey 2020 published state mosque-growth rates only for NY (+33%), CA (+24%), NJ (+29%), TX (+35%) and FL (+33%). For the other top states the survey summary did not publish a state rate, so the table labels them “Trend not published” — a national increase does not prove an individual state grew, so no direction is claimed for them. No top state, metro or county in the published sources showed a decreasing trend; where no trend was published, this tracker says so instead of omitting the field. Metro trends: Houston, Atlanta, Orlando and Minneapolis are described as fast-growing in the sources; NYC, Chicago, Detroit and LA are large and growing more slowly in % terms. County-level trend series are not published — counties are labeled “no published trend” in the map detail logic for that reason.
Just outside the top 10: Florida (157 mosques — 4th most in the U.S., Miami / Orlando / Tampa), Minnesota (largest Somali community in the U.S., Minneapolis–St. Paul, est. >2% of state), Georgia (metro Atlanta, among the fastest-growing), plus Ohio, North Carolina and Arizona with growing suburban communities. Exact 2020 counts for those states are lower and less consistently published, so this tracker lists the verified top 10 rather than guessing the rest.
Muslim Americans are overwhelmingly metro and suburban. Metro figures are ranges compiled from state totals, mosque counts and community studies — treat them as estimates, not census counts.
Most diverse in the world — South Asian, Arab, West African, Bangladeshi & African American. Hubs: Queens, Brooklyn, Bronx, North Jersey.
Dearborn + Hamtramck anchor. Predominantly Arab American (Lebanese, Iraqi, Yemeni) + Bangladeshi & Bosnian communities.
One of the oldest communities in the Americas. Bridgeview, South Side, northwest suburbs. 109 mosques statewide, most in Chicagoland.
Iranian (“Tehrangeles”), Arab, South Asian & Afghan communities across LA / Orange County / Inland Empire.
80+ mosques in Houston area alone. Diverse professional + refugee communities; Texas total 313k statewide.
MENA / Arab ancestry — 2020 Census, first Arab-majority city in U.S. history (pop. ~110,000). Dearborn has the proportionally largest Muslim community of any large U.S. city and is home to the Islamic Center of America, the largest mosque in North America.
Important nuance: Arab ≠ Muslim. Dearborn's Arab population includes Christians and others. Community estimates put Muslims at a large share — often cited around half the city — but there is no official religious census for the city.
Small city (pop. ~28,000) inside Detroit. Frequently described as America's first Muslim-majority city; in 2021 voters elected what was reported as the nation's first all-Muslim city council and a Muslim mayor.
Other dense hubs to know: Paterson, NJ (“Little Ramallah”), Bridgeview, IL, Minneapolis, MN (Somali hub — Cedar-Riverside), and Philadelphia, PA (deep African American Muslim roots).
County-level religion data is only published in the decennial Religion Census and is mosque-based, so this section shows the counties researchers and local reporting consistently identify as hubs, with what anchors each one. Every card lists Estimate, % and Trend explicitly — where no county-level figure was published, the field says “not published” rather than inventing a headcount. Use the state map above for county context: each county sits in a state shown on the map with its published % and trend. These counties are on the map — zoom into any region (or use a card's “View on map” button) and county outlines fade in with the hub counties below outlined in dark teal; hover a highlighted county for its readout, and keep zooming for city and street detail.
Muslim civic participation has risen sharply: ISPU-tracked voter registration among eligible Muslims rose from ~60% in 2016 to ~85% in 2025 in recent polling summaries, with 255 Muslim elected officials & judges in 26 states cited in Pew's 2026 portrait. CAIR counted at least 42 Muslim winners nationwide in the 2025 cycle. High-profile wins included Zohran Mamdani as New York City's first Muslim mayor (2025) and Ghazala Hashmi as Virginia lieutenant governor — the first Muslim woman to win statewide office in the U.S. Four Muslims serve in the U.S. House. Influence is increasingly suburban — in swing counties around Detroit, Chicago, Northern Virginia and North Jersey.

Mosques: ISPU / Bagby U.S. Mosque Survey 2020 — 2,769 mosques nationally; NY 343, CA 304, TX 224, FL 157, NJ 141.
Metro ranges: Compiled ranges in The Global Statistics / community studies summary of Religion Census + mosque data — NYC 600–700k, Chicago 400–450k, LA 250–300k, Detroit 200–250k, Houston 150–180k. Ranges, not point counts.
Dearborn: 2020 Census MENA ancestry 54.5% of ~110,000 residents; first Arab-majority U.S. city (2023 reporting). No federal source gives a direct Muslim % for Dearborn — ancestry is not religion.
Snapshot built Nov. 5, 2026 (data as published Sept.–Oct. 2026). This is a static snapshot — it does not update live. For the next update, the key releases to watch are Pew's next Religious Landscape Study and the 2030 Religion Census / Mosque Survey.
