OMAHA, Neb. (AP) — A new report says an August survey of business supply managers suggests slow or no economic growth over the next several months in nine Midwest and Plains states.

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.
