About this ranking

People under 18 in families or living alone with income below the official US poverty thresholds, as a percentage of people under 18 whose poverty status can be determined. United States: Census Bureau Small Area Income and Poverty Estimates (SAIPE) for the nation, states and counties.

A model-based single-year estimate; the national figure is the one-year American Community Survey estimate. The Census Bureau advises comparing years from 2006 on only. Absolute thresholds set by the US government, so not comparable with the EU at_risk_of_poverty_rate. The rate for all ages is 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.
