Problem
Five states had mid-decade congressional redistricting between the
118th and 119th Congresses (i.e., before the 2024 election): GA, NC,
NY, AL, LA. If our districts/*.h5 files for those states were built
against the 118th-Congress boundaries, any TY 2025+ dashboard
attributing impacts to "GA-7" or "NC-1" etc. is labelling households
under the wrong polygon.
GA is the confirmed case — the dashboard at
georgia-2026-tax-changes was pulling 118th polygons from ArcGIS,
which has McBath at GA-6 / McCormick at GA-7 (the pre-2023 layout).
The 119th Congress seated McCormick at GA-6 and McBath at GA-7.
NC, NY, AL, LA need the same audit — confirm whether the current
h5 files reflect 119th boundaries or are still on 118th, and refresh
where needed.
Asks
Why now
Closes the loop on the 119th-Congress map state. Without this,
dashboards built today that route through the existing h5 files may
silently attribute impacts to the wrong representatives in five of
the largest delegations.
