Revising Health Insurance Data Collection: ACS Updates for 2025

The American Community Survey (ACS) is set to revise its health insurance coverage question beginning in 2025, following extensive testing and stakeholder feedback.

This modification is part of the ACS's ongoing efforts to enhance the accuracy of health insurance data, ultimately benefiting agencies like the Department of Health and Human Services in resource allocation efforts. Conducted in 2022, the Content Test employed a sample of 120,000 housing units to scrutinize the structure and clarity of survey questions. The results indicated slight shifts in insurance estimates, with minor decreases noted in both public and private coverage—specifically in direct-purchase and Medicaid policies within these sectors. This evolution aims to refine understanding without impacting response rates significantly or the overall insured rate. A reduction in respondents citing multiple insurance types suggests improved question clarity.

The ACS's commitment to data quality was further demonstrated through a Medicaid match study. This analysis verified the consistency of self-reported data against official records from the Centers for Medicare and Medicaid Services. The study confirmed that both control and test question versions maintained similar accuracy, albeit with marginal differences in false reporting rates. The release of the 1-year health insurance coverage estimates is scheduled for October, with users urged to cautiously interpret 2025 data due to the updates in methodology. Until bridging research is concluded, health insurance variables will be omitted from the ACS 2021-2025 5-year tables, slated for inclusion in subsequent data releases starting with 2022-2026.

The Impact of the ACS Update

The implications for insurance professionals are multi-faceted. For agencies, the adjustment enhances the accuracy of health data, providing a solid foundation for underwriting analysis and strategy planning. For brokers and agents, understanding the subtleties in data shifts can aid in better advising clients regarding insurance needs and available options.

• The ACS revision follows a 2022 test with 120,000 households, confirming clearer survey questions.
• There are slight decreases in public and private insurance coverage, offering nuanced insights.
• Future data releases will exclude some variables until adjustment analysis is finalized.
• The change will influence data reliability for areas with smaller populations through supplemental tables.

The ACS's strategic information updates exemplify how survey modifications can pivot toward data accuracy and transparency, shaping the landscape for health insurance insights and policy decisions. Insurance industry professionals should remain attuned to these changes to refine their services and strategies accordingly.
