Demographics of Iranian immigrants in the US: quick snapshot
The Iranian immigrant population in the United States is older, highly educated, and heavily concentrated in a few states-especially California-with the largest shares living in major metro areas such as Los Angeles, Texas, New York, and Virginia. Recent U.S.-focused analyses describe roughly 385,000 Iranian immigrants in 2019 and about 375,000 Iranian Americans living in California alone in 2024, underscoring both long-term settlement and continued growth in the broader Iranian-origin population.
Population size and growth
The size of the Iranian diaspora in the United States expanded rapidly after the 1979 Iranian Revolution and the 1980s refugee and asylum flows, then continued growing more slowly in later decades. A migration policy analysis found that the Iranian-born population rose from 122,000 in 1980 to 283,000 in 2000 and reached 385,000 by 2019, while a 2026 summary using ACS-based methods put the broader Iranian American population at roughly 375,000 in California and about two-thirds of the national total in four states.
Because U.S. surveys do not always identify Iranian Americans directly, estimates vary depending on whether a source counts only the foreign-born, ancestry, parentage, or a broader Iranian-origin category. That means the safest reading is that the community is large, mature, and still evolving through both immigration and U.S.-born generations.
Age and generation
The age profile of Iranian immigrants is notably older than that of many other immigrant groups. One widely cited demographic profile reported a median age of 55 for Iranian immigrants in 2019, compared with 46 for the overall foreign-born population and 37 for the U.S.-born population.
That older age structure reflects the history of migration from Iran, especially the large wave that followed the 1979 revolution and the sizable second-generation population that has since formed in the United States. UCLA researchers reported that the median age of first-generation Iranians is broadly in the 45-to-70 range, while American-born second-generation Iranians are much younger, generally in the 20-to-40 range.
| Indicator | Iranian immigrants / Iranian Americans | Context |
|---|---|---|
| Estimated Iranian-born population, 2019 | 385,000 | Foreign-born Iranians living in the U.S. |
| Median age of Iranian immigrants | 55 | Older than both the overall immigrant and native-born populations. |
| Share under age 18 | 2% | Very small child population among the foreign-born Iranian group. |
| Share age 65+ | 28% | Indicates a large retirement-age cohort. |
| California share | More than half | Largest state concentration of Iranian immigrants. |
| Estimated Iranian Americans in California | 375,000 | Broader Iranian-origin estimate using ACS methods. |
Where they live
The geographic concentration of Iranian immigrants is one of the most striking features of the population. More than half live in California, and recent ACS-based estimates show the largest national concentrations in California, Texas, New York, and Virginia, which together account for about two-thirds of U.S. Iranians.
Los Angeles remains the symbolic and demographic center of Iranian American life, but settlement is diversifying. UCLA notes that younger first-generation Iranians are increasingly choosing states in the South and Midwest rather than clustering exclusively on the West Coast, a sign that new arrivals are responding to job markets, housing costs, and family networks across the country.
Education and income
Iranian immigrants are widely described as one of the most educated immigrant groups in the United States. Migration Policy Institute research found that they have higher educational attainment than the foreign-born population overall and significantly higher median household incomes than both the U.S.-born and overall immigrant populations.
Pew's 2026 analysis reported that about 76% of Iranian immigrants and 86% of U.S.-born Iranians had at least some college education in 2024, a strong signal of broad educational attainment across generations. That same analysis also found that Iranian Americans are about as old overall as other Americans, but that national average masks the sharper age gap between foreign-born and U.S.-born Iranians.
"Iranian immigrants, as a group, are older than both the total foreign-born and U.S.-born populations."
Arrival history
The modern migration wave from Iran to the United States is closely tied to political upheaval and educational migration. Historical summaries show a pre-revolution student and professional migration stream, followed by a much larger post-1979 flow that included many refugees and asylum seekers during the 1980s.
Pew reported that during the 1980s almost two-thirds of Iranian immigrants arrived as refugees or asylees, while in later decades about one-third did so. That shift helps explain why the community includes both highly educated professionals and people whose migration was shaped by displacement and conflict.
Community profile
The community profile of Iranian immigrants is unusually diverse in religion, language, profession, and generation, even though public conversation often reduces the group to a single stereotype. Iranian Americans include Muslims, Christians, Jews, Zoroastrians, Baha'is, and secular households, and many are bilingual or multilingual, especially in families that have been in the U.S. for several decades.
Occupationally, the community includes a high share of entrepreneurs, engineers, physicians, academics, and other professional workers, which helps explain the group's above-average income profile. At the same time, the presence of retirees, refugees, and younger second-generation adults means the population is not economically or socially uniform.
Illustrative breakdown
The following illustrative snapshot summarizes the main demographic patterns most often associated with Iranian immigrants in the United States. The exact numbers vary by source, year, and definition, but the direction of the trends is consistent across reputable analyses.
- Older than the average immigrant population, with a large 65-plus segment.
- Highly concentrated in California and a few other states.
- Strong educational attainment across both immigrants and U.S.-born descendants.
- Split between first-generation arrivals and a growing second-generation population.
- Historically shaped by post-1979 political migration and refugee flows.
What the numbers mean
For researchers and journalists, the key interpretive point is that Iranian immigrants in the U.S. are not a newly arriving group but a long-settled diaspora with substantial generational depth. Their demographics reflect a community that combines older first-generation migrants, highly educated professionals, and a younger U.S.-born population that is changing the group's future profile.
This also means policy discussions should avoid treating Iranian immigrants as a single bloc. Age, place of arrival, refugee history, income, religion, and generation all affect how Iranian Americans live, work, and identify, and those differences matter when interpreting political preferences, housing patterns, language retention, and social needs.
Frequently asked questions
Historical context
The modern Iranian American demographic story begins well before the 1979 revolution, but that event fundamentally reshaped the size, timing, and composition of the community. The post-revolution era brought a large wave of students, professionals, and later refugees, creating a diaspora that is now institutionally established, geographically concentrated, and multigenerational.
Today, Iranian immigrants in the United States are best understood as a mature diaspora with high educational attainment, a strong West Coast historical core, and an increasingly national footprint. That combination makes the group especially important in discussions of immigration, assimilation, transnational identity, and the future of Iranian American civic life.
Expert answers to Iranian Immigrant Demographics Where They Live And Why It Matters queries
How many Iranian immigrants live in the US?
Recent official and ACS-based summaries place the Iranian-born population in the U.S. at about 385,000 in 2019, while broader Iranian-origin counts are higher because they include U.S.-born descendants and ancestry-based identification.
Where do most Iranian immigrants live?
Most live in California, and the largest additional concentrations are in Texas, New York, and Virginia. Together, those four states account for about two-thirds of U.S. Iranians in one recent national analysis.
Are Iranian immigrants highly educated?
Yes. Multiple recent analyses describe Iranian immigrants as one of the most educated immigrant populations in the United States, with very high rates of at least some college education and above-average income outcomes.
Is the Iranian American population mostly first-generation?
No. The population now includes a substantial and growing U.S.-born second and third generation, which is one reason the community's age profile is younger overall than the foreign-born Iranian subgroup alone.
Why do estimates for Iranian Americans vary?
Estimates differ because U.S. surveys do not always identify Iranian Americans as a distinct category, so researchers use different combinations of birthplace, ancestry, race, and parentage to build counts. That methodological difference can shift totals even when the underlying population is the same.
