How the city count works

The calculator uses the standard normal distribution (the bell curve) with a mean of 100 and a standard deviation of 15 to find the share of people at or above an IQ score, then multiplies that share by the city's metropolitan population.

These are theoretical estimates based on the global IQ distribution. In reality, distributions vary by region because of education, nutrition, economic development and selective migration. Cities that are economic or academic hubs may have somewhat higher averages.

Population figures are metropolitan area estimates and may differ from city proper or administrative boundary populations.

Frequently asked questions

How is the city IQ count calculated?

The calculator uses the normal distribution (bell curve) with mean 100 and SD 15 to find the percentage of the population at or above a given IQ. That percentage is multiplied by the city's population to estimate the number of people. These are statistical estimates that assume a perfectly normal distribution.

Are IQ distributions the same in every city?

Not exactly. IQ distributions can vary by region because of education access, nutrition, economic development and selective migration. Cities that attract knowledge workers may have higher average IQs. This calculator uses the global standard distribution as a baseline estimate.

How many geniuses (IQ 140+) live in New York City?

Based on the standard IQ distribution, about 31,500 people in New York City (population 8.3M) would have an IQ of 140 or higher. That is the top 0.38% of the population. In practice the number may be higher because of selective migration of highly educated professionals.
