Average IQ by State

IQ, or the Intelligence Quotient, is a means by which we can measure the intellectual capabilities of any individual. IQ is measured on a scale from 0 to 200, although theoretically there is no upper limit. It is determined through a standardized test that assesses the individual’s critical thinking and ability to identify patterns and sequences. Many argue that the method of measuring IQ is not up to par, as it is a subjective test that cannot fully account for the differences in each individual’s way of thinking. However, it is still reliable information, useful to make comparisons from state to state.

The average IQ in the U.S. is 98, which falls within the range of average intelligence. About 68% of the population has an IQ between 85 and 115, with women generally having a higher IQ than men.

States With the Highest IQs

The states with the highest IQ scores in the country, including Massachusetts, North Dakota, Vermont, and Minnesota are located predominantly in the Northeast and the North of the Midwest. Many theories have tried to explain why some states are “smarter” than others, including proposals that argue that colder climates could favor higher IQs. Other factors like genetics may play a role in the development of an individual’s intelligence. Yet, these propositions do not provide the full picture of why Massachusetts or New Hampshire have higher IQ scores. A crucial element to look at is education: it is proven that easy and affordable access to robust and efficient education is key in explaining IQ variations. The states with the highest IQs all have great education systems and programs. Massachusetts for example is home to internationally-recognized universities including Harvard University, the Massachusetts Institute of Technology (MIT), and Boston University. As for New Hampshire, the state has one of the highest percentages of adults who have a high school diploma.

Massachusetts, with an average IQ of 104.3, is the state that ranks highest for average IQ in the US, but only by 0.1, as New Hampshire comes in second with a score of 104.2. The state of North Dakota is positioned in third place with a score of 103.3 and only 0.5 points above Vermont, placed fourth, with an average score of 103.8. Minnesota in fifth place, holds an IQ score of 103.7, only 0.1 point below that of fourth-place Vermont. Both Maine, sixth place, and Montana, seventh, have an average IQ score of 103.4. The state of Iowa ranked eighth and Connecticut, ranked ninth, both hold an average IQ score of 103.1. Wisconsin, ranked tenth, has an IQ score of 102.9. As one can see, the difference between these states’ average IQ is small.

The 10 states with the highest IQ are:

  1. Massachusetts – 104.3
  2. New Hampshire – 104.2
  3. North Dakota – 103.8
  4. Vermont – 103.8
  5. Minnesota – 103.7
  6. Maine – 103.4
  7. Montana – 103.4
  8. Iowa – 103.2
  9. Connecticut – 103.1
  10. Wisconsin – 102.9

States With the Lowest IQs

While some states may be considered to be the “smartest”, it also suggests that others do not rank as high. The states with the lowest IQs are California, Louisiana, and Mississippi. It should be noted that these states are not in any way less smart per se, but have a greater concentration of individuals with lower IQ scores. Various factors may favor lower IQ, such as education, wealth, nutrition, and public policies. Health is another key factor. Indeed, a recent study showed that the development of the brain during childhood consumes close to 90% of a newborn calorie intake. If this newborn is contaminated by an infectious disease, part of its energy will be directed to fighting the disease, and not to develop the brain. All three states with the lowest IQs in the U.S. – Mississippi, Louisiana, and California – have high levels of infectious disease as well. This suggests that infectious disease could be one of the primary causes of low IQ in these three states.

The state of Mississippi, with a score of 94.2, has the lowest average IQ score in the United States. The second worst IQ score in the country is Louisiana with an IQ score of 95.3, this is only 0.2 points less than California, which has an IQ score of 95.5 and places the state in third position. Hawaii is ranked in fourth place, by a 0.1 difference, and has an IQ score of 95.6. Both Alabama, fifth place, and New Mexico, sixth, have an IQ score of 95.7 and once again only a 0.1 difference compared to fourth place Hawaii. The state of Nevada, in seventh place, has an IQ score of 96.5. In eighth place, the state of Arizona has an IQ score of 97.4 and by a 0.1 difference, Arkansas takes ninth place Arkansas with a score of 97.5. Tennessee comes in tenth with an average IQ score of 97.7.

The 10 states with the lowest IQ are:

  1. Mississippi – 94.2
  2. Louisiana – 95.3
  3. California – 95.5
  4. Hawaii – 95.6
  5. Alabama – 95.7
  6. New Mexico – 95.7
  7. Nevada – 96.5
  8. Arizona – 97.4
  9. Arkansas – 97.5
