## Processing Steps
Official files were downloaded from official sources via the RDH website.
Where necessary, files were combined into one statewide file and column names were changed to match PL fields.
The PL field assignment was checked by comparing adjusted PL data in blocks where populations did not appear to change.
They matched in all instances.
Please note that some states removed population as part of their adjustment, so the sum of an adjusted column may differ from that of its unadjusted equivalent.
