Average IQ in Los Angeles (United States): Estimates & Key Factors
Estimated Avg IQ
102
IQ Range
99–105
Region
Americas
Los Angeles is America's entertainment capital and second-largest city, home to UCLA, USC, and Caltech — one of the world's greatest scientific research institutions. The city's diverse economy spans entertainment, aerospace (SpaceX, Boeing), technology, fashion, and international trade. Caltech's extraordinary concentration of scientific talent — arguably the highest-ranked university in the world by research output per faculty member — significantly elevates the city's intellectual profile despite being located in Pasadena rather than LA proper. SpaceX, aerospace companies, and biotech firms further concentrate STEM professionals.
Important note: City-level IQ estimates are especially approximate. They reflect selection effects — cities attract educated, ambitious migrants — as well as local education quality, economic conditions, and available data. These figures do not reflect the intelligence or potential of any individual resident. For context on what IQ scores measure, see our guide to IQ.

Los Angeles vs. United States National Average
Los Angeles's estimate of ~102 sits above United States's national estimate of ~98, consistent with the selection effects large cities often show — educated, ambitious people migrating toward economic and cultural capitals.
Where This Number Comes From
No comprehensive IQ survey exists for Los Angeles — or for almost any city. The figure above is an extrapolation: it starts from national-level estimates (compiled cross-national datasets such as Lynn & Vanhanen's, alongside PISA and TIMSS assessment data), then adjusts for the city's educational attainment and economic composition. Those national compilations are themselves debated in the academic literature, and a city-level extrapolation inherits all of that uncertainty and adds more. Treat the range shown above as an illustrative band, not a measured confidence interval.
Frequently Asked Questions
What is the average IQ in Los Angeles?
Los Angeles's estimated average IQ is around 102, above the US national average. Despite its entertainment industry reputation, LA has a significant STEM sector anchored by Caltech, SpaceX, aerospace companies, and a large biotech cluster.
How does Caltech affect Los Angeles's cognitive profile?
Caltech, located in Pasadena in the greater LA area, has perhaps the most extreme positive selection effect of any university in the world — with the lowest acceptance rate and highest research productivity per student of any institution. Its faculty and graduate students significantly elevate the region's cognitive profile.
How does LA compare to San Francisco?
San Francisco (107) scores higher than LA (102) primarily due to the Bay Area's extraordinary concentration of technology companies and the unique cognitive selection of Silicon Valley. LA's more diverse economic base, while intellectually rich, creates less extreme selection for any single type of cognitive ability.
