This dataset is a supplemental analytic data release published outside the standard annual County Health Rankings cycle. It includes updated measure values for a subset of health outcomes, clinical care, community conditions, and social and economic factors that were updated more recently than the 2025 Annual Data Release.

The dataset provides county- and state-level measures, including measure values, numerators, denominators, 95% confidence intervals, and reliability or suppression flags where available. Measures are identified using numeric measure IDs and follow the standard County Health Rankings analytic variable naming conventions (e.g., raw values, denominators, confidence intervals, and flags).

Several measures are available with race- and ethnicity-specific breakdowns for counties with sufficient sub-population sizes. For selected health care provider measures, both rate-based values and population-to-provider ratios are included.

Data are not available for Connecticut counties and planning regions in this supplemental release; users should refer to the 2025 Annual Data Release for the most recent data for those geographies.

This supplemental dataset should be interpreted in conjunction with the 2025 Annual Data Release and the official Supplemental Release documentation, which describes measure definitions, data sources, suppression criteria, and comparability considerations.
