Health care in America is presently much debated. Finding understandable and verifiable data and information that describe issues associated with health care is often hard to derive from the media and other sources of information.
The U.S. Census Bureau has published a report on recent measures of income, poverty and health insurance in the United States. Generally, the U.S. Census Bureau is regarded as authoritative in measuring such socio-economic data. Compare these figures with those you hear in the media.
