About this ranking

People living in families or alone with income below the official US poverty thresholds, as a percentage of people whose poverty status can be determined. United States: Census Bureau Small Area Income and Poverty Estimates (SAIPE), all ages.

Absolute thresholds set by the US government, so not comparable with the EU at_risk_of_poverty_rate.

Every value in the ranking comes from the same publisher and the same period, so the counties are compared on one definition. Equal values share a rank.
