With 50 states in the Union and 100 percent to go around, the average state’s contribution to U.S. GDP
would technically be two percent. While a lot of states are in that percentage range, there are some economic powerhouses that surpass that goal easily.
The six most populous states, California, Texas, Florida, New York, Illinois and Pennsylvania, are also the six biggest contributors to U.S. GDP, according to the Bureau of Economic Analysis.
Yet, California is way ahead of the competition as far as per-capita contribution goes. While 11 percent of Americans live in California, the state contributed 14.5 percent to GDP in 2018. New York state, where just short of 6 percent of Americans live, had a share of 8.2 percent of GDP in 2018. Florida, which has a 6.4 percent share of population, only contributed 5.1 percent of GDP, likely because a lot of retirees live in the state.
As far as regions go, the Southeast, including populous states Florida, Georgia and North Carolina, contributed the biggest share of roughly a fifth to U.S. GDP. The Far West had a slightly smaller share, largely driven by California.
