According to the ACS (American Community Survey) from the US Census Bureau, in 2014 (most recent year available), about 38 million Americans (12% of the population) living in about 20 million households did not have health insurance.
The lower a family's income is, the less likely that they can purchase health insurance, according to 2008 US Census figures. About 14.5% of households with $50,000 to $75,000 in income did not have health insurance. While 24.5% of households with $25,000 or less income went without health insurance.
