VRscores Employer Parquet 2012-2024

Employer-year panel dataset derived from the VRscores 2024 release. Each row corresponds to a VRscores employer identifier (VRID) and calendar year. Variables include raw and imputed counts of matched workers by voter registration party (Democratic, Republican, Other), two-party margins, partisan diversity indices, and employer name. A restricted crosswalk maintained outside this release links VRIDs to original RCIDs and supplements them with ultimate parent metadata, GVKEYs, and modal location fields for approved users. The dataset is derived from a matching of employment records from Revelio Labs (April 2025) with voter registration data from the L2 voter file (November 2024) using ensemble linkage techniques. Small employers (<5 matched workers) are excluded, one-to-one matches are enforced, and the final release contains 6,258,838 employer-year rows covering roughly 534,000 employers and 24.5 million matched workers.
