SOURCE & METHODOLOGY Distressed Designation and County Economic Status Classification System

The Appalachian Regional Commission (ARC) uses an index-based county economic classification system to identify and monitor the economic status of Appalachian counties. The system involves the creation of a national index of county economic status through a comparison of each county’s averages for three economic indicators—three-year average unemployment rate, per capita market income, and poverty rate—with national averages. The resulting values are summed and averaged to create a composite index value for each county. Each county in the nation is then ranked, based on its composite index value, with higher values indicating higher levels of distress.

County Economic Levels

Each Appalachian county is classified into one of five economic status designations, based on its position in the national ranking.

Distressed
Distressed counties are the most economically depressed counties. They rank in the worst 10 percent of the nation's counties.

At-Risk
At-Risk counties are those at risk of becoming economically distressed. They rank between the worst 10 percent and 25 percent of the nation's counties.

Transitional
Transitional counties are those transitioning between strong and weak economies. They make up the largest economic status designation. Transitional counties rank between the worst 25 percent and the best 25 percent of the nation's counties.

Competitive
Competitive counties are those that are able to compete in the national economy but are not in the highest 10 percent of the nation's counties. Counties ranking between the best 10 percent and 25 percent of the nation's counties are classified competitive.

Attainment
Attainment counties are the economically strongest counties. Counties ranking in the best 10 percent of the nation's counties are classified attainment.

County Economic Indicators

Three–Year Average Unemployment Rate
The three-year average unemployment rate is a measure of long-term structural unemployment that allows for the comparison of counties across state borders. The unemployment rate is calculated by dividing the three-year sum of persons unemployed by the three-year sum of the civilian labor force.

Per Capita Market Income
Per capita market income is calculated by dividing total personal income, less transfer payments, by population. Transfer payments include retirement and disability insurance benefit payments, medical payments, income maintenance benefit payments, unemployment insurance benefit payments, veterans benefit payments, and other such payments.

Poverty Rate
The poverty rate is computed by dividing the number of persons living below the poverty threshold by the number of persons for whom poverty status has been determined.

Time Series

ARC computes new county economic levels each fiscal year based on the most current data available at the beginning of the calendar year of computation. The time series used for each economic indicator and fiscal year is listed in the table below.
