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.
