OMAHA, Neb. (AP) – Figures from a survey of supply managers in nine Midwest and Plains states have risen for the third month in a row, suggesting more improvement in the regional economy. A report issued today (Friday) says the Mid-American Business Conditions Index rose to 50.6 in March from 50.5 in February and 48.3 in January. The survey results are compiled into a collection of indexes ranging from zero to 100. Survey organizers say any score above 50 suggests economic growth. A score below that suggests decline.

Creighton University economist Ernie Goss oversees the survey, and he says a strong U.S. dollar and economic weakness among the nation’s chief trading partners continues to slow regional growth. The survey covers Arkansas, Iowa, Kansas, Minnesota, Missouri, Nebraska, North Dakota, Oklahoma and South Dakota.
