The Current Population Survey Annual Social and Economic Supplement (CPS ASEC) is the official source for national estimates of income, poverty and health insurance coverage. The 2026 CPS ASEC collected data from approximately 89,000 households across the 50 states and the District of Columbia to produce these estimates for the U.S. population.

To make inferences from this sample, the CPS ASEC is controlled to independent national population estimates by age, sex, race, and Hispanic origin. The 2026 CPS ASEC will be controlled using the Census Bureau’s Vintage 2025 population estimates for March 1, 2026; while the 2025 CPS ASEC used Vintage 2024 estimates.

All 2024 estimates in the annual Income, Poverty and Health Insurance CPS ASEC reports, which will be released in September 2026, will be updated to reflect Vintage 2025 population controls in order to show year-to-year changes across consistently weighted data. This working paper presents key estimates and comparisons between the original published 2024 estimates (based on Vintage 2024 controls) and the reweighted 2024 estimates (based on Vintage 2025 controls). Overall, the difference in population controls resulted in statistically significant but substantively minor differences in 2024 estimates.
