Region
Americas
Chicago is America's third-largest city and its financial capital for commodities and derivatives trading, home to the University of Chicago (ranked among the world's top 10, famous for economics and law), Northwestern University in nearby Evanston, and the Chicago School of Economics. The University of Chicago has produced more Nobel Prize winners in economics than any other institution. Chicago's financial sector, legal profession, and consulting industry attract high-achieving professionals from across the country. The city's diverse population includes large communities with varying educational backgrounds, producing a moderate urban premium over the US average.
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.

Chicago vs. United States National Average
Chicago's estimate of ~103 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 Chicago — 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 Chicago?
Chicago's estimated average IQ is around 103, above the US national average. The city's financial sector, elite universities, and professional services industries attract high-achieving residents, though its large, diverse population creates substantial variation.
Why is the University of Chicago so important to economics?
The University of Chicago's economics department pioneered free-market economic thought and has produced over 90 Nobel laureates. The 'Chicago School of Economics' has had outsized influence on global economic policy through figures like Milton Friedman, Gary Becker, and Eugene Fama.
How does Chicago compare to New York and Los Angeles?
Chicago (103) scores above Los Angeles (102) and below New York (105). Los Angeles's entertainment industry, while high-profile, creates less of a cognitive selection effect than New York's finance or Chicago's commodities trading. Chicago's financial sector creates a strong pull for mathematically oriented talent.
