Since 2022, Supplemental Poverty Measure (SPM) and official poverty measure estimates have diverged, with SPM rates increasing or being not statistically different while the official poverty rate has fallen. Research at BLS and the Census Bureau has identified the annual updating procedure of SPM poverty thresholds — for both living standards and price changes — as the primary driver of this divergence (Schild 2023; Creamer 2024, 2025). Building on this research, this paper presents a potential method to produce SPM poverty thresholds by updating the standard of living decennially and adjusting for changes in price levels. The method improves the annual updating of the existing poverty thresholds as regular updating keeps poverty thresholds modern while adjusting for prices simplifies year-to-year comparisons. The proposed anchored poverty measure uses anchored thresholds which are anchored twice across the SPM series in 2010 and 2020 with price adjustments in the intervening years using the Consumer Price Index for All Urban Consumers (CPI-U). In 2024, the anchored poverty rate was 11.3 percent, 1.7 percentage points lower than the published SPM rate of 12.9 percent. In terms of the historical series, the anchored SPM shows a 26.0 percent decline (4.0 percentage points) in poverty since the Great Recession compared to a 14.4 percent decline in the SPM rate (2.2 percentage points). The divergence largely arises due to published SPM rates increasing or being not statistically different in 2023 and 2024 compared to a falling anchored SPM rate in those two years. Estimates using alternative price indices show that the CPI-U is a middle ground between different inflation assumptions. This research is part of ongoing work at the Census Bureau which studies changes and improvements to the SPM and does not represent a planned change in methodology.
