Uninsured people are less likely to receive medical care and more likely to have poor health status. The cost of poor health among uninsured people was almost $125 billion in 2004 (Hadley & Holahan, 2004).

The financial burden of medical care is also high for uninsured individuals; almost 50% of personal bankruptcy filings are due to medical expenses (Jacoby, et al., 2000). Uninsured individuals report more problems getting care, are diagnosed at later disease stages, and get less therapeutic care.
