OMAHA, Neb. (AP) — Business remains strong in nine Midwest and Plains states, but a new monthly survey suggests that growth is slowing as concerns about trade and tariffs increase. The region's overall economic index decreased to 61.8 in June from May's 67.3, but any score above 50 indicates growth. Creighton University economist Ernie Goss says the trade concerns and more interest rate increases are likely to slow the region's economy. The survey results are compiled into a collection of indexes ranging from zero to 100.
