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. For example, oil, coal and natural gas rich states, including North Dakota, experienced strong income growth in the early part of the decade, which has since leveled off or reversed. Meanwhile, income growth has begun to shift to states with a stronger foothold in healthcare and professional services, as well as the West and Southeast.
