Average IQ By State

The Human Intelligence Quotient, or IQ, has long been a measure of cognitive capabilities, with its scores offering insights into both individuals and larger populations. On a national level, the average IQ of the United States is reported to be 98. However, this single value fails to capture the vast disparities between different states. By analyzing public data from IQ tests, SAT and ACT scores, and educational attainment levels, this article takes a more granular look at the "Average IQ by State" in the U.S., revealing not just average values but the patterns and regional nuances that shape this distribution.

Key findings from the data include:

• The state with the highest average IQ is Massachusetts, ranking first with an average IQ of 104.3. This state is renowned for its educational institutions, possibly contributing to the elevated IQ levels. 
• The second and third highest ranking states are New Hampshire and North Dakota, with average IQ scores of 104.2 and 103.8, respectively.
• On the other side of the spectrum rests Mississippi at the rank of 50, with a lower average IQ of 94.2. This ranking may reflect socio-economic factors that affect residents' access to quality education, a significant aspect contributing to IQ levels.
• Racial, educational, and economic disparities likely factor into state variations, highlighting the complex matrix of conditions that influence intellectual development and testing outcomes.
