A monthly Associated Press analysis shows California, Michigan and South Carolina suffered the most financial pain during May.

Unemployment, home foreclosures and bankruptcies rose during the month, contributing to a higher score for the average U.S. county in the AP's Economic Stress Index.

Williams County in northwest Ohio is one of a handful of manufacturing communities that have suffered the sharpest increases in stress scores over the past year.

The AP calculates a score from 1 to 100 based on each county's unemployment, foreclosure and bankruptcy rates. The higher the score, the higher the economic stress.
