OMAHA, Neb. (AP) -- An economist who oversees a monthly economic survey of nine states in the Midwest and Plains says the economic recovery has spread to more industries.

The Mid-America Business Conditions Index rose last month to 58.4 from 55.9 in January.

Creighton University economist Ernie Goss says the region's growth had been limited to agriculture and energy sectors. He says the February survey indicates the growth has spread to most industries, except construction.

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