Europe
Stockholm is Scandinavia's largest city and a global leader in technology entrepreneurship, having produced more billion-dollar tech companies per capita than almost any city in the world, including Spotify, Klarna, and King. Sweden's comprehensive welfare state, excellent public education, and strong healthcare system support cognitive development across the population. Stockholm concentrates Sweden's educated professional class and is home to KTH Royal Institute of Technology and Stockholm University. The city's high English proficiency and international business culture attract educated global 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.

Stockholm vs. Sweden National Average
Stockholm's estimate of ~103 sits above Sweden's national estimate of ~99, 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 Stockholm — 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.
