Clay County is a county located in the U.S. state of Kentucky. As of the 2020 census, the county population was 20,345.[1] Its county seat is Manchester.[2] The county was formed in 1807 and named in honor of Green Clay (1757–1826).[3] Clay was a member of the Virginia and Kentucky State legislatures, first cousin once removed of Henry Clay, U.S. Senator from Kentucky and Secretary of State in the 19th century.
Clay County was established in 1807 from land given by Floyd, Knox and Madison counties. The courthouse burned in January 1936.[4]

There were 8,556 households, out of which 36.9% had children under the age of 18 living with them, 58.6% were married couples living together, 12.4% had a female householder with no husband present, and 24.7% were non-families. 22.5% of all households were made up of individuals, and 9.0% had someone living alone who was 65 years of age or older. The average household size was 2.62 and the average family size was 3.06.
The age distribution was 25.4% under the age of 18, 9.2% from 18 to 24, 32.6% from 25 to 44, 22.5% from 45 to 64, and 10.3% who were 65 years of age or older. The median age was 35 years. For every 100 females, there were 111.7 males. For every 100 females age 18 and over, there were 112.6 males.

Clay County has been rock-ribbed Republican since the Civil War, having last voted for a Democratic nominee for president in 1860 when it supported Kentucky native and Southern Democrat John C. Breckinridge.[7] In the last one hundred years the only Republicans to receive less than sixty percent were Bob Dole, who still won the county by nearly 25 percent, and Barry Goldwater, who held the county by seventy-five votes amidst a Democratic landslide in 1964. In 2008 John McCain received 77.5% of the vote.[8] The county is located in Kentucky's 5th congressional district represented by Representative Hal Rogers.[9]
In July 2010, The Washington Post named Clay County the unhealthiest county in Kentucky, and one of the unhealthiest in the nation. Clay County also featured prominently in a June 2014 article in The New York Times about the difficulty of living in poverty in eastern Kentucky, ranking last in overall ratings for counties in the United States. The factors which accounted for Clay county's low ranking were unemployment, prevalence of disabilities, obesity, income, and education.[10] The Times declared Clay County the "hardest place to live in the U.S."[11]
Of 3,142 counties in the United States in 2014, Clay County ranked 3,137 in the longevity of female residents and 3,109 in the longevity of male residents. Males in Clay County lived an average of 68.6 years and females lived an average of 73.6 years compared to the national average for longevity of 76.5 for males and 81.2 for females. Moreover, the average longevity in Clay County declined by 0.4 years for males and 3.4 years for females between 1985 and 2014 compared to a national average for the same period of an increased life span of 5.5 years for men and 3.1 years for women. High rates of smoking and obesity and a low level of physical activity appear to be contributing factors to the lowered longevity for both sexes.[12]
