High-paying blue-collar jobs lifted incomes in West Virginia, New York and Illinois last year, even though the states lost residents, while farmers and government workers shared the pain of more stagnant income in Nebraska, Maryland and Washington, D.C.The new per-capita income numbers show how national policies and international markets directly affect state and local pocketbooks. Deregulation in the United States and a heat wave in China boosted coal demand in West Virginia, for example, while overseas mining and farming led to more giant truck manufacturing in Illinois. At the same time, U.S. tariffs hurt Nebraska soybean farmers.The administration’s trade war with China took a toll on Nebraska, one of the nation’s most agriculture-dependent states. Sales of soybeans and other food to China suffered, said Ernie Goss, a regional economist at Creighton University in Omaha. Low oil prices also kept a lid on profits from corn-based ethanol, he said.Nebraska ranked last in per-capita income growth, with almost no change after inflation, at about $52,110.
