The number of uninsured people in Missouri has jumped by 80,000 in one year. The Census Bureau says Missouri had 646,000 people without health insurance last year, up from 565,000 in 2001. The bureau reports most of the increase is because of the loss of employer-provided insurance. Missouri’s uninsured rate is almost 11%. Enrollment in Medicaid, which might be a partial reflection of loss of insurance elsewhere, has gone up 6% in the last fiscal year in Missouri.
