There are obviously an infinite number of health care-related statistics that can be cited, many based upon the results of surveys. The U.S. Centers for Disease Control, for example, conducts health care surveys of the public to ascertain data on access to and quality of health care in different regions of the country. The CDC's National Center for Health Statistics lists a number of different categories of statistics. Two in particular stand out:
"Recent Declines in Infant Mortality in the United States, 2005-2011"; and
"Health Behaviors of Adults: United States, 2008-2010.
Privately-operated institutions that collect health care statistics, the accuracy of which are difficult to verify, include:
--HealthCareProblems.org: Provides statistics on the number of Americans without health insurance, the amount people pay for health insurance, total health care expenditures in the United States for a given calender year, and so on. While this website specifies that it is not associated with any "corporation, medical or health industry sponsorship," the fact that includes links to major health insurance companies should suffice to indicate the site's perspective;
--HealthPaconline.net: Provides statistics on a wide range of health care-related topics, including data on Medicaid and Medicare. This website also states that is "not associated with any corporate sponsorship or political affiliation," and that is "just a number of individuals who share a concern of the current health care system's spiraling costs and the large number of insured citizens who not have access to quality health care." Unlike "HealthCareProblems.org, this website does provide information, like identities of staff, so that the user can better gage the site's integrity.
So, there is a credible, U.S. Government health care website, which provides primary source statistics, and two privately-owned websites, which provide statistics that may be accurate, but with which the user would be wise to exercise caution.
