AP analysis: Economic stress rises in Midwest

WASHINGTON (AP) - Counties in the Midwest and South that have a high number of autoworkers have seen a jump in economic stress levels, according to an Associated Press monthly analysis.

But Midwestern states also have seen the largest decreases in economic stress since the recession ended. That's primarily because of growth in manufacturing. Ohio has added 7,600 factory jobs in the past year.

The AP's Stress index calculates a score from 1 to 100 based on unemployment, foreclosure and bankruptcy rates. A higher score signifies more economic stress.

Under a rough rule of thumb, a county is considered stressed when its score exceeds 11. By that standard, about a quarter of the nation's 3,141 counties were stressed in May, roughly the same as in April.
