Suburban superiority

The following table shows estimated average IQ among 8th graders taking the NAEP math and reading assessments in 2013 by the type of community where the school is located, broken out into four categories: City, suburb, town, and rural. The scores for both tests are on a 500 point scale, with a standard deviation of 37 on the math assessment and 34 on the reading assessment. In the subsequent table, these are converted into IQ estimates with a mean of 98--corresponding to the national average NAEP scores of 283.62 for math and 266.02 for reading--and a standard deviation of 15. The math and reading scores are weighted equally:


Those quiet, leafy suburbs might cognitively outperform other community types but they're seething hotbeds of atomized ennui and dysfunction. Just go watch American Beauty already!

NAEP filter variable used: UTOL4

Check again in a generation, after Section 8, gentrification, more mass immigration, and more white flight work their charm.

Obviously, the solution is to move everybody in the cities into the suburbs. Problem solved!
