LINCOLN, Neb. (AP) – New U.S. Census estimates show Nebraska’s median household income increased more than $300 per family between 2009 and 2010, the largest proportional gain of any state. The report released Thursday shows income grew to $48,408 last year, a nearly 1 percent gain. The only larger increase was the District of Columbia. David Drozd, a researcher for the Center for Public Affairs Research, attributes Nebraska’s growth to its low unemployment and higher commodity prices that helped farmers. Rural western Nebraska saw the largest income increase, while the Omaha area saw a decline. Nebraska was one of only five states that saw median income growth. The others were South Dakota, North Dakota, West Virginia and Virginia.
