OMAHA, Neb. — Economic growth lies ahead for nine Midwestern and Plains states despite pullbacks in the energy sector, according to a monthly report released on Monday.

The overall Mid-America Business Conditions Index climbed to 57.0 in February from 54.8 in January, the report said.

“However, areas of the region linked closely to the energy sector, including ethanol, are experiencing pullbacks in economic activity,” said Ernie Goss, director of Creighton University’s Economic Forecasting Group, who oversees the survey.

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

Economic optimism ebbed last month, according to the business confidence index, which dropped to 58.4 from 61.8 in January.
