Islam in America

The Nation of Settlers team conducted a nationwide inventory over three months, cataloging and verifying all mosques and Islamic centers in the United States. The total count in October 2026 was 2,952.

Pew estimates about 5.5 million Muslims of all ages in the United States in 2026, using its 2023–24 Religious Landscape Study, Census Current Population Survey data, and earlier Muslim population surveys. It is an estimate, not a religious census.

The museum says the Nation of Islam grew to more than 300,000 members by 1964. This is a historical estimate, not a measured 2026 membership total.

Retrospective estimate for the United States in 1990: 1.529 million. This older historical estimate was not recalculated on the same basis as Pew’s newer 2010 and 2026 estimates.

Revised all-ages US Muslim estimates: about 2.77 million in 2010 and 4.05 million in 2020.

The chart's pre-1915 zero is a documented-mosque floor, not an observed national total. The reconstructed 1970/1980/1990 values derive from founding dates; 1994/2000/2010/2020 are national survey counts. The 2026 chart value extrapolates the 2000–2020 average: 2,769 + 6 × ((2,769 − 1,209) ÷ 20) = 3,237. It is not a measured count.

The map uses the 2020 national mosque benchmark and Census populations. Enumeration took place in 2019; interviews described pre-pandemic conditions. This is not a 2026 count. The survey includes congregations with regular prayer and other activities, with provisions for some Shia institutions. It excludes prayer-only facilities and several movements, including Nation of Islam, Moorish Science Temple, Ismaili and Ahmadiyya organizations.

An institution called an Islamic center may meet the mosque definition; the name alone does not establish a separate category. The survey reports 2,769, while an independent 2020 table reports 2,771. That discrepancy remains unresolved; this map consistently uses the national survey’s state table.

Denominator: July 1, 2025 resident population, NST-EST2025-ALLDATA, POPESTIMATE2025; released January 2026. Per million = eligible mapped locations in the state divided by all state residents, multiplied by 1,000,000. This is not the percentage of residents who are Muslim. The location snapshot and population observation year are labeled separately.

The map selects 15 metropolitan areas by estimated Muslim population. Its percentages refer to entire metropolitan areas, not individual cities or neighborhoods.

NAIT says the fund extends limited interest-free loans to help communities complete Islamic centers, mosques, and schools.

CAIR-SFBA reports submitting a letter supporting a mosque's appeal of local permit conditions. This documents advocacy, not construction funding.

59% of Muslim adults were foreign-born; the survey was conducted in English and Spanish. This is the foreign-born share of resident adults, not an immigration flow. The reported race/ethnicity shares are rounded: White 30%, Asian 30%, Black 20%, Hispanic 11%, and other or multiple races 8%; they do not measure Arab ancestry. The 2017 country-of-birth breakdown is older and is not reweighted to this newer estimate.

Pew found that 82% of Muslim adults surveyed in 2017 were US citizens: 42% born in the US and 40% naturalized; 18% were noncitizens. The survey also reports country-of-birth shares. These historical adult figures cannot be applied to the 2026 all-ages population estimate, and noncitizens are not necessarily temporary-visa holders.

The 2014 online opt-in survey of 560 Latino Muslims found 31% reported Mexican ancestry, 22% Puerto Rican ancestry, and 62% were US-born. It was not a representative sample and cannot establish the origins of Pew's 2023–24 Hispanic Muslim respondents.

Table 2 estimates 3,403,016 people in 2000 through a Census-based model. The author considers it an upper bound. It is not a Pew estimate and is intentionally unconnected to Pew’s 2007–2026 series.

Pew estimated 2.35 million Muslims of all ages in 2007. The page's 2007–2026 annual-change scenario uses this estimate and Pew's 2026 estimate; it is an illustration, not a forecast.

The numbered link leads to the calculation and its assumptions above.

The citizenship table on page 312 reports that 78% of US Muslim adults were citizens, 21% were noncitizens, and fewer than 1% did not answer. It does not classify noncitizens by immigration status and does not cover children.

Main-series US population projections: 345.074 million in 2030, 355.309 million in 2040, and 360.639 million in 2050. These are national denominators for the scenario shares, not projections of Muslims; the same denominator is used for each policy scenario without reprojecting the US total under that policy.

The US population was approximately 342.9 million when the chart was calculated. The 2026 Muslim baseline of 5.5 million implies a share of about 1.6%.

The archived baseline lists Cuba, Iran, North Korea and Syria. Syria is excluded from Tier 1 following the August 24, 2026 rescission. These are US designations, not a joint Western classification.

Findings are attributed to the administration and retain their source date; they are not independent verification of conditions today.

Section 4(g) identifies passport/civil-document and screening deficiencies in Syria. A screening finding is distinct from a state-sponsor designation. Coverage is limited to the stated source rules, not every country with terrorist activity. The June 2025 request to review Egypt is not itself a finding of deficiencies.

The four advisory examples are selected, not an exhaustive list of countries with a terrorism risk indicator. A travel advisory addresses risk to travelers; it is not a measure of attack frequency, a state-sponsor designation, or an immigration-screening finding.

The 2.5 children-per-woman figure is a modeled historical US Muslim fertility estimate, combining estimates of 2.6 for immigrants and 2.2 for US-born Muslims. It is not an observed 2026 fertility rate.

The final 2024 US total fertility rate was 1,599.5 births per 1,000 women, or approximately 1.60 children per woman. The 2.1 figure is an approximate replacement level, not the current US average.

The report's country table gives France's estimated Muslim share as 7.5% in 2010 and 8.8% in 2016. The scenario chart applies that 1.3-percentage-point change over six years to the US share from 2026. This is a short-period population-share analogy, not France's immigration rate or a US forecast.

Pew's 2015 model used a 2010 baseline and projected continued migration alongside age structure, fertility, mortality and religious switching. Its 8.1-million 2050 endpoint predates Pew's 2026 US Muslim estimate of 5.5 million. The historical projection is not plotted as a current scenario.

New America’s downloadable deadly-attack table, version 29, contains 16 records classified as “Jihadist,” totaling 122 victim deaths. The latest included incident is March 12, 2026. We retain the source’s classifications, which are research categories rather than a claim that every case produced a terrorism conviction. Its category excludes Hamas and Hezbollah. This is a dated source snapshot, not a complete live incident feed.

Metro groupings combine nearby municipalities: Boston includes Cambridge; Seattle includes Skyway; New York–Newark includes West Orange; Riverside–San Bernardino is separate from Los Angeles; Fort Hood is assigned to Killeen–Temple. The 2014 multi-state record is split into three Washington victims and one New Jersey victim, without double counting. The Boston record includes the subsequent killing of an MIT police officer. Pins use approximate principal-city coordinates. Ranking is by deaths, not attack frequency or population-adjusted risk.

Scope: the January 1, 2026 proclamation, not all subsequent visa policies. Exceptions include lawful permanent residents and qualifying dual nationals. The proclamation applies to people outside the United States without a valid visa on its effective date; it does not revoke previously issued visas. Palestinian Authority travel documents are covered separately from country nationality.

The map uses the proclamation’s full-suspension countries in proposed Tier 1 and includes additional author-proposed countries. Its tiers are not official US classifications or a classification of residents by religion.

Hundreds or thousands is a historical range, not an enumerated count. The chart's early population values are site scenarios.

Thousands or tens of thousands refers to arrivals over the early period, not people alive in any one year.

Early founding dates do not establish the number of mosques still active in a given year.

The number at any historical date cannot be determined from surviving records.

Temporary admission and authorized stay are governed by immigration status and the I-94, not simply the visa stamp's expiration. Eligible nonimmigrants may apply to extend or change status. This source does not count Muslim temporary-status residents; the chart's departure input is hypothetical.
