MAP - A Third of America's Economy Is Concentrated in Just 31 Counties [View all]
Just 31 counties, or the top 1% by share, made up 32.3% of U.S. gross domestic product in 2018, according to data released last week by the Bureau of Economic Analysis that included nearly 20 years of county-level GDP data. That's despite these counties only having 26.1% of employed Americans and 21.9% of the population last year. Their combined GDP share is also up from a recession low of 30.1% in 2009.
The nations economy is becoming increasingly concentrated in large cities and by the coastsand less so in rural countiesspurring the question of whether rural areas will be increasingly left behind. The growing concentration of the countrys economic activity could impact a variety of things from infrastructure spending to labor mobility, but its unclear how rural areas will fare as their share of economic output continues to dwindle.
