Returns a data frame mapping historical district names to their current canonical names (as of 2025). NM PED districts have changed names over the years, creating apparent appearances/disappearances in time series. This mapping allows consistent district identification across years.
Details
The canonical name is the most recent name used by NM PED (2024-25 data). All mappings are keyed by district_code to ensure accuracy.
