(AP) — A new monthly survey of business leaders suggests the economy continues growing at a strong pace in nine Midwest and Plains states. The overall index for the region crept up to 73.5 in June from May’s already strong 72.3 reading. Any score above 50 suggests growth. Creighton University economist Ernie Goss said the region is expected to keep growing and return to pre-pandemic levels early next year.  Business leaders said supply delays are causing problems in manufacturing and high inflation remains a concern. The monthly survey covers Arkansas, Iowa, Kansas, Minnesota, Missouri, Nebraska, North Dakota, Oklahoma and South Dakota.
