The United States is the only wealthy, industrialized nation that does not have a universal health system.
In 2006, the percentage of Americans without health insurance was 15.8%, or approximately 47 million uninsured.
Between 84.2% with health insurance in 2006, coverage was provided through an employer for 59.7%, purchased separately by 9.1%, and 27.0% was financed by the government (Medicare , Medicaid, military). (There is some overlap in coverage figures.)
The main reason given for the lack of health insurance coverage in 2005 was the cost (over 50%), loss of employment or a change in employment (24%), Medicaid benefits stopped (10%), the ineligibility for family insurance coverage due to age or leaving school (8%). More than 40 million adults said they needed but did not receive one or more of these health services (medical care, prescription drugs, mental health care, dental care or eyeglasses) in 2005 because he could afford.
Medicaid, which accounted for 12.9% of health coverage in 2006, is a health insurance program jointly funded by federal and state governments to provide medical care for qualifying low-income people.
Medicare, a federal health insurance program that covers health care for most people 65 years of age and older and disabled people, accounted for 13.6% of health coverage
Medicare operates with 3% overhead, non-profit insurance costs 16%, and private (nonprofit) insurance costs 26%
