The overlooked geography of American poverty

Data: U.S.

Census ; Map: Erin Davis/Axios California and Louisiana have something surprising in common: Both have among the nation's highest poverty rates when the cost of living is factored in, according to Census Bureau data.

Why it matters: Southern states dominate America's traditional poverty rankings.

But that familiar geographic divide starts to disappear when more of a family's financial realities are taken into account.

Axios analyzed 2023-2025 state poverty estimates from the Census Bureau to see what happens when housing, taxes, medical expenses and government benefits enter the picture.

What we found: Under the Census' traditional-style official measure, Louisiana had a 19.6% poverty rate and California was at 10.7%.

New Hampshire was the lowest at 5.4%.

The South is home to 10 of the 11 states where the traditional poverty rate significantly outpaced the national average.

California's poverty rate jumped by nearly two-thirds to 17.8% under the broader Supplemental Poverty Measure , or SPM.

Louisiana remained near the top at 19%.

Maine posted the nation's lowest SPM rate at 6.4%, followed by Nebraska at 7.5% and Minnesota at 7.9%.

How it works: The traditional measure compares pretax cash income with a family-size threshold that doesn't change by geography.

The SPM adds benefits such as SNAP and housing assistance, factors in taxes and tax credits, subtracts work and medical expenses, and adjusts for geographic differences in housing costs.

Zoom out: The official poverty rate fell for a third straight year to 10.2%, while child poverty reached a record-low 13.4%.
