Counties were ranked based on percentage of residents with bachelor's degree, "median household income, unemployment rate, disability rate, life expectancy and obesity," Allan Flippen writes for The Upshot, a Times blog that did the analysis. "We tried to include other factors, including income mobility and measures of environmental quality, but we were not able to find data sets covering all counties in the United States."
The 10 lowest ranked counties are Breathitt, Clay, Jackson, Lee, Leslie and Magoffin in Eastern Kentucky, along with Humphreys County, Miss.; East Carroll Parish, La.; Jefferson County, Ga.; and Lee County, Ark. Los Alamos County, New Mexico, ranks highest, and six of the top 10 are suburbs of Washington D.C. To view the interactive map of where your county ranks click here. (Upshot map)
