A fresh examination of U.S. Census Bureau data reveals a striking shift in how American poverty is measured and where it is concentrated. While Southern states traditionally dominate standard poverty rankings, that geographic divide changes significantly when researchers account for housing costs, taxes, medical expenses, and government benefits.
Under the traditional, official poverty measure—which compares pretax cash income against a fixed family-size threshold that does not adjust for geography—Louisiana recorded a 19.6% poverty rate, while California stood at 10.7%. New Hampshire posted the nation’s lowest traditional rate at 5.4%. In total, the South accounts for 10 of the 11 states where the traditional poverty rate significantly outpaced the national average.
However, a different picture emerges under the Supplemental Poverty Measure (SPM), which incorporates government benefits such as SNAP and housing assistance, factors in taxes and tax credits, subtracts necessary work and medical expenses, and adjusts for local housing costs. Under this broader framework, California’s poverty rate jumps by nearly two-thirds to 17.8%, placing it near Louisiana, which remains high at 19%.
Conversely, states with lower cost-of-living pressures and different tax or benefit structures show vastly different outcomes under the SPM. Maine recorded the nation’s lowest SPM rate at 6.4%, followed by Nebraska at 7.5% and Minnesota at 7.9%.
Federal data also outlines broader national economic trends during the 2023–2025 survey period. The official poverty rate fell for a third consecutive year to 10.2%, and child poverty reached a record low of 13.4%. At the same time, real median household income climbed to a record $87,460 in 2025. Yet, despite these positive economic indicators, the national SPM remained statistically unchanged at 13.1%, sitting nearly three percentage points above the official rate.
Federal statisticians emphasize that the SPM is not intended to replace the official poverty rate. Instead, the Census Bureau designed the metric as an alternative lens to capture household resources and unavoidable living expenses that the traditional measure misses.
Because state samples in the Current Population Survey are smaller, the Census Bureau recommends utilizing three-year averages for state-level figures rather than single-year estimates. The 2023–2025 estimates analyzed by researchers highlight that looking at income alone remains insufficient for understanding whether families across different regions can successfully make ends meet.
