SOURCE & METHODOLOGY
Distressed Designation and County Economic Status Classification System, FY 2007 – FY 2013
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.

Note: Five-year poverty estimates from the U.S. Census Bureau's American Community Survey were first used in the fiscal year 2012 county economic status designations. The decennial census no longer produces poverty data. A five-year estimate provides the most reliable and comparable data for all U.S. counties, particularly those with small populations. A new five-year poverty estimate will be incorporated into the county designations each fiscal year.

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.
