Dec 31 (Reuters) - The pace of business activity in the U.S. Midwest slowed in December, a report showed on Wednesday.
The Institute for Supply Management-Chicago Business Barometer declined to 58.3, its lowest reading since July, after a November reading of 60.8.
A Reuters poll of economists expected a reading of 60.1.
A reading above 50 indicates expansion in the regional economy.
