Money income does not reflect the fact that some families receive part of their income in the form of noncash benefits such as food stamps, health benefits (Medicaid), and public housing. Data on noncash benefits can be found in Current Population Survey Detailed Tables POV-07 and POV-08.
The annual Poverty in the United States report provides estimates of how many people are lifted out of poverty by noncash benefits using the Supplemental Poverty Measure.
