The B.A. Divide
[imgbelt img=BAIncomeQuintiles528.jpg]The country is segregating by education, as people with college degrees
cluster in some communities and not others.
This education gap among U.S. counties has been growing since the 1970s. The maps below show the distribution of educated adults across every U.S. county.
The red counties have percentages of adults with B.A. degrees lower than the national average. Blue counties have a higher percentage of adults with college degrees than the national average.
The redder the county, the lower the percentage of educated adults. The dark blue counties have the highest percentage of adults with B.A. degrees.
The first map comes from 1990. The next map shows the distribution of college educated adults in 2000. And the final map shows estimates from 2009.
Scroll through the maps. As time passes, a greater proportion of the U.S. landscape is falling behind the national average. Meanwhile, blue areas are getting darker.
Educational attainment predicts local economic success. As the share of the population with a college degree increases, the local unemployment rate decreases.
“There should be nothing surprising about this fact,” writes Harvard University economist Ed Glaeser. “Skills have long been among the best predictors of urban success, as measured by wages, wage growth, population growth and housing price increases.”
That strong relationship between education and economic success remains true in rural America.
(To read more from Glaeser on the relationship between education and economic growth, go here.)
We compared the 204 counties with the highest percentages of adults with B.A. degrees with the 204 counties with the smallest percentage of adults with college degrees. (The top ten percent of the nation’s 2,038 rural counties versus the bottom ten percent.)
The most educated counties had higher incomes than the least educated counties ($37,283 versus $24,605); lower unemployment in July of this year (7.5% versus 12.2%); and a lower poverty rate (12.5% versus 21.1%).
As the country continues to separate by levels of education, it is reasonable to assume that the economic differences from place to place will grow.
This gap has life and death consequences. People with more college degrees live longer than do those who haven’t earned a B.A. And the mortality gap between those with and without college degrees “grew dramatically” between 1960 and 2000, according to a recent report from the National Bureau of Economic Analysis.
(The paper, Working Paper 15678, is titled, “Explaining the Rise in Educational Gradients in Mortality.”)
By 2000, a college-educated 25 year old could expect to live 7 years longer than peers with less education. Researchers could find no behavioral reason for this gap — not a difference in smoking or weight gain, for example.
Education levels are not uniform across rural America. Below are lists of the 50 rural counties with the highest and lowest percentages of adults with college degrees.
The counties with the most educated adult populations are largely found in the Mountain West. In fact, of the ten counties with the fastest growing proportion of college-educated adults, seven can be found in this region.
The rural counties with the smallest percentages of college-educated adults are largely in the South and in Texas.
