Source-level coverage and dataset provenance for every indicator loaded into the platform.
Current source-level footprint based on loaded county indicators and latest coverage metadata.
Note on years: the year in each Data source name is the dataset's file/release version (e.g., the AHRF 2023-2024 release). The Data years column is the actual span of measurement years in the data, which can differ — a single release often bundles measures from several years (AHRF spans 1976-2024).
