A business conditions index compiled by Creighton University points to a slower Wyoming economy in the months ahead.

The Wyoming index stood at 47.5 in December, down from 51.4 in November and 73.4 in October. A number greater than 50 indicates an expansionary economy in the next three to six months.

"The global economic slowdown and declining commodity prices have begun to slow growth in the state's large mining and natural resources industry," Economics Professor Ernie Goss said in a press release. "Even though Wyoming has been shielded from the national recession, I do expect some negative outcomes for the first half of 2009 as the state's unemployment rate rises slightly."

Individual components of the December index were new orders at 25.0, production at 37.5, delivery lead time at 62.5, inventories at 50.0 and employment at 62.5.

The index for the Mountain States region overall fell to a record low in 41.3 in December, down from 46.2 in November.

"For the second straight month, the index dipped below growth neutral. These readings are consistent with a significant economic downturn," Goss said.

Wyoming's employment index was significantly better than Utah and Colorado, the other states in the region. Wyoming registered 62.5, compared to 38.3 for Colorado and 36.5 for Utah.
