Research

Geocode study addresses to 2020 tracts and block groups, document the accuracy of every match, and keep the data for the life of the project.

The job

Health, housing and social-science studies attach each participant or record to a Census geography, then join it to the ACS, to exposure data or to neighbourhood indices, and keep the dataset for years.

How geocode.net fits

  • fields=census returns state and county FIPS, tract, block group, place and ZCTA on 2020 geographies, with the vintage stated in every response.
  • accuracy_type and accuracy give you a documented match quality per record for the methods section, and a filter for sensitivity analyses.
  • Batch 10,000 at a time from Python or R; results in input order.
  • Storage is unrestricted. A longitudinal dataset geocoded today does not need to be re-run to stay within anyone's terms.
  • Data sources are public domain (National Address Database, TIGER/Line), which simplifies data-management plans and IRB descriptions.

See adding census tracts to addresses for the join to ACS tables.
