Mirrors create_data_center_census_tract_table.py but at ZIP Code
Tabulation Area geography (2020 boundary vintage, since ZCTAs are only
redrawn each decennial census). Builds data_center_zcta_2024 (607 ZCTAs
hosting >=1 facility, joined to ACS 2024 5-year demographics) and adds
master_data_centers.zcta_geoid, parallel to the existing tract geoid
column. Used to verify the income/education premium for DC host
communities holds at ZIP-code resolution, not just census-tract
resolution, for the dc-siting-politics paper.
