Rural-urban differences, in the association of food insecurity and hunger w
ith income suggest that the cost of living is substantially lower in rural
than in urban areas. This implies that the official poverty rate overstates
rural economic hardship compared with that in urban areas. Geographic diff
erences in cost of living implied by the association between food insecurit
y and income provide some validation of the cost: of housing adjustment pro
posed by the National Academy of Sciences (NAS) panel on improving the meas
urement of poverty, but suggest that the NAS adjustment generally overcorre
cts for cost of living and would be seriously problematic in some regions.
