About this ranking
People with income in the past 12 months below the official US poverty thresholds, as a percentage of people whose poverty status is determined. United States: American Community Survey five-year estimate, where the period shown is the last year of the five-year span.
The headline single-year rate for states and counties is poverty_rate (SAIPE). Poverty status is not determined for people in institutions, military group quarters or college dormitories, or for unrelated children under 15. 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.
