North Dakota led the country in per capita personal income gains between 2010-2015, according to data released by the Bureau of Economic Analysis (BEA). While average (mean) incomes rose 18.4 percent around the U.S. during that time, North Dakota incomes rose by 26.8 percent from $42,964 in 2010 to $54,376 in 2015. Changes in mean income can obscure discrepancies between demographic groups and concentration of wealth, but demonstrate some of the key economic trends of the last few years.
