OMAHA, Neb. (AP) — A new survey suggests the economy remains strong in nine Midwest and Plains states, but business leaders are concerned about the ongoing trade disputes. The overall economic index for the region slipped to 57.5 in September from August’s 61.1, but it remained in positive territory. Creighton University economist Ernie Goss says he expects business will slow down but continue growing in the next few months because of the trade concerns and rising interest rates.

The survey results are compiled into a collection of indexes ranging from zero to 100. Survey organizers say any score above 50 suggests growth. A score below that suggests decline. The survey covers Arkansas, Iowa, Kansas, Minnesota, Missouri, Nebraska, North Dakota, Oklahoma and South Dakota.
