State personal income grew 0.7 percent on average in the second quarter of 2017, after increasing 1.4 percent in the first quarter, according to estimates released today by the federal Bureau of Economic Analysis. Each of the major aggregates of personal income -- net earnings, property income and personal current transfer receipts -- grew more slowly than in the first quarter. Iowa, with a 0.1 percent growth rate, was among the three slowest-growth states in personal income with Nebraska and West Virginia, with each state growing at less than half the national rate. Personal income grew 1.3 percent in Nevada, faster than in any other state. Farm earnings declined for the nation and in every state in the second quarter and was the leading contributor to slow earnings growth in many states. In Nebraska, Iowa and North Dakota, the decline in farm earnings reduced earnings growth by half a percentage point or more.
