Despite boasting eight of the world's top 10 universities, the United States still has many areas within its borders where the majority of people are poorly educated. In fact, according to Pearson, on the whole, American schools rank 14th globally.
With this in mind, using 2015 data from the American Community Survey, geographic and real estate data site FindTheHome explored differences in educational attainment across different U.S. counties to determine the least educated place in every state. To do so, FindTheHome identified the county in every state with the highest percent of adults without a high school degree. The educational attainment percentage considers the highest educational achievement of the population over 25 years old. Individuals with no high school degree or G.E.D. equivalent were included. FindTheHome started with the state with the highest of the low-educated counties, counting down to the state with the highest percentage of adults without high school diplomas.
In many cases, these same counties also have a sizable percentage of residents with a bachelor's degree and above. For example, Kalawao County, Hawaii has 17.9 percent of residents with no high school degree, but it's also an outlier on this list with 43.3 percent of residents possessing a bachelor's degree or above. Eleven counties have a higher percentage of residents with a bachelor's degree or above than residents without a high school degree. While many counties are rural, Bronx County, New York, and Philadelphia County, Pennsylvania, are also on this ranking, with 29.75 percent and 18.57 percent of residents with no high school degree.
