Region
Middle East & Africa
Istanbul is Turkey's economic and cultural capital, a transcontinental city spanning Europe and Asia that serves as a crucial bridge between Eastern and Western markets. The city concentrates Turkey's most educated professionals in finance, manufacturing, media, and increasingly in technology. Istanbul's universities, including Bogazici University (modeled on Columbia University), Istanbul Technical University, and several others, produce large numbers of well-trained graduates. Turkey has invested significantly in expanding university access over the past two decades, and Istanbul captures the most cognitively selective migrants from across the country.
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.

Where This Number Comes From
No comprehensive IQ survey exists for Istanbul — 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.
