Put enough Iranians in a city and something predictable seems to happen.
A Persian grocery store appears. Then a kebab restaurant. Then several dentists. A cardiologist. An immigration lawyer. At least six real-estate agents.
And eventually a disagreement about which kebab restaurant is actually good.
There is an economic explanation hiding inside the joke.
One city, three in ten
Iranian Americans are extraordinarily concentrated geographically. According to the Pew Research Center, about 750,000 Iranian Americans lived in the United States in 2024 (by Pew’s count, which includes U.S.-born children of Iranian parents). The population has grown more than fourfold since 1980.
| Where | Iranian Americans (Pew, 2024) |
|---|---|
| United States | 750,000 |
| California | 375,000 |
| Los Angeles metro | 230,000 |
| New York metro | 45,000 |
| San Francisco metro | 40,000 |
| Washington, D.C. metro | 40,000 |
| San Jose metro | 30,000 |
| San Diego metro | 25,000 |
That’s roughly three in ten Iranian Americans living around one American city.
Why?
Networks compound
The first immigrant arrives with very little local knowledge. Where should I live? Who speaks Persian? Where can I find work? Where is the synagogue, mosque, church, temple or cultural community? Where will my parents feel comfortable? Where might my children meet other Persian families?
Once a community becomes established, each additional immigrant faces lower costs by moving there. Every new family makes the place a little more useful for the next one: another Persian-speaking doctor, another grocer who stocks the right rice, another congregation, another set of potential in-laws.
That’s a network effect — the same force that makes a phone network or a marketplace more valuable as more people join.
Economists have measured it. Research on post-1965 U.S. immigration found new immigrants are considerably more geographically concentrated than natives and gravitate toward existing co-ethnic communities. A study of Mexican migrants found that larger hometown networks in the U.S. improved the chance of employment and better-paying jobs. And when Sweden assigned refugees to cities essentially at random, those placed among more people from their own background went on to earn more, not less.
Timing matters too. Iranian migration to the U.S. grew fastest in the 1980s and 1990s, after the 1979 revolution and during the Iran-Iraq war. Where the first large wave landed shaped where the network formed.
The puzzle
Here’s what makes the Iranian case genuinely interesting. The same research finds that more-educated immigrants tend to cluster less — they have more options and rely less on co-ethnic networks to find work.
Iranian Americans are among the most educated groups in the country: Pew reports about 65% of Iranian Americans 25 and older hold at least a bachelor’s degree, and about 35% hold an advanced degree.
They cluster anyway. That suggests the pull isn’t just about finding a job. It’s about family structure, language, food, faith, and the practical value of living near people who share a migration story.
Not just Los Angeles
New York has a substantial Iranian population. So do the Bay Area and Washington. Outside the United States, Canada’s largest Iranian community is in Toronto, but Greater Vancouver stands out for its concentration: about 1.8% of the population reported Iranian origin in Canada’s 2021 Census, roughly the same share as in Los Angeles.
Uniformity not required
Iranian communities themselves are hardly uniform. They include Muslims, Jews, Bahá’ís, Christians, Zoroastrians, Armenians and people who identify primarily as secular.
They argue about politics. Religion. The monarchy. The revolution. Israel. America. And probably rice.
But shared language, food, family structure, history and migration experience still create powerful social infrastructure.
The interesting story isn’t that Iranians all think alike. They clearly don’t. It’s that communities don’t require ideological uniformity to produce economic and cultural network effects.
Sometimes all you need is a grandmother asking why you moved somewhere without a Persian market.
The Zesht box
Follow the incentive
- What behavior does this reward?
- Settling where the community already is, and opening a business — a grocery, restaurant, dental practice or realty office — that serves it.
- What does it discourage?
- Being the first Iranian family in a town with no Persian market, which carries a real cost in convenience, services and grandmother approval.
- What becomes more expensive?
- Housing in the hub neighborhoods, where network demand stacks on top of already tight supply in Los Angeles, Toronto and Vancouver.
- What becomes scarcer?
- Iranian community infrastructure outside a few metro areas — which is exactly why the hubs keep winning.
- Who receives the benefit?
- Newcomers, through lower search costs, and the entrepreneurs serving a dense, highly educated customer base.
- Who ultimately pays?
- Mostly nobody directly. The costs show up as higher local housing demand and less spread in where the diaspora settles.
- What happens when people have another option?
- Networks spread. Secondary hubs such as the Bay Area, Washington, New York, San Diego and Vancouver grow once each reaches a self-sustaining critical mass.
Goal → mechanism → result
The scorecard
- 1The goal
- For the migrant, not a policy: build a new life with the least risk and cost — housing, work, language, schools, faith communities, familiar food and family.
- 2The mechanism
- Early arrivals settle in a few places. Each additional arrival makes those places more useful to the next.
- 3The incentive
- Moving where the network already exists lowers search costs and the risk of isolation; businesses serving the community earn more where it is dense, which reinforces the pull.
- 4The observed result
- Extreme concentration: about half of Iranian Americans live in California and three in ten around Los Angeles (Pew, 2024). In Canada, Toronto and Vancouver dominate.
- 5The unintended consequences
- Added housing demand in already-expensive neighborhoods, and highly visible enclave identities that are both celebrated ("Tehrangeles") and stereotyped.
- 6What supporters say
- Co-ethnic networks provide jobs, information, credit, childcare and support; natural-experiment evidence from Sweden found enclaves raised immigrant earnings.
- 7What critics say
- Enclaves can slow integration, concentrate economic risk in a few local markets, and preserve old political divisions.
- 8What the evidence actually shows
- Immigrants cluster more than natives and follow co-ethnics; larger networks improve job outcomes; enclave residence can raise earnings. Iranian Americans cluster despite very high education levels.
- 9What remains uncertain
- How much of the clustering reflects network effects versus the timing of the 1980s migration waves, climate and the role of specific early communities — and whether later generations disperse.
Questions people ask
How many Iranian Americans are there?
Pew Research Center estimates about 750,000 Iranian Americans in 2024, about 0.2% of the U.S. population. Pew's count includes people born in Iran, people reporting Iranian ancestry, and U.S.-born children of Iranian parents; about 59% are immigrants.
Why do so many Iranians live in Los Angeles?
About 230,000 Iranian Americans — three in ten — live in and around Los Angeles, according to Pew. Many arrived in the 1980s and 1990s after the 1979 revolution and during the Iran-Iraq war, and research on immigrant networks shows newcomers tend to settle where their community already lives because it lowers the cost of finding housing, work and services.
Where do Iranians live in Canada?
In Canada's 2021 Census, about 200,000 people reported Iranian ethnic origin, plus about 80,000 reporting Persian (with some overlap). The largest community is in Toronto (about 88,900 of Iranian origin), followed by Greater Vancouver (about 45,800), where Iranians make up roughly 1.8% of the population.
Are Iranian Americans all Muslim?
No. The community includes Muslims, Jews, Bahá'ís, Christians, Zoroastrians, Armenians and many people who are secular. A 2014 survey commissioned by an Iranian American advocacy group found under a quarter identified as Muslim, though that survey is dated and its figures should be treated as approximate.
