Average IQ in Singapore City (Singapore): Estimates & Key Factors
Estimated Avg IQ
110
IQ Range
107–113
Region
Asia
Singapore City is the entirety of the city-state of Singapore and consistently achieves the highest PISA scores in the world. Its education system is internationally renowned for its rigor, particularly in mathematics and science, and its bilingual policy ensures all students are proficient in both English and their mother tongue. Singapore's status as a global financial hub attracts highly educated expatriates from around the world, adding to an already highly credentialed resident population. Government investment in early childhood education, nutrition, and healthcare is among the highest in Asia relative to GDP.
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.

Singapore City vs. Singapore National Average
Singapore City's estimate of ~110 sits above Singapore's national estimate of ~108, 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 Singapore City — 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.
