2020 Census Daily Self Response Rates

This repo contains the daily 2020 US census self response rate data at a census tract level. It's updated daily at around 3:30pm with new data pulled from the census API.

The script that does the bulk of the work is /code/update_counts.py. It performs the following steps:

  • Downloads the latest data from the census API.
  • Performs an interpolation between 2020 census tracts and 2010 census tracts.
  • Adds geometry for 2020 census tracts and saves the results as GeoJSON.

The data here is primarily being collected to power the Hester Street census map but can be used by anyone who finds it useful.

Data files

  • /data/raw : Contains the raw data pulled from the API. There is a combined CSV for each day and a folder that contains a file for each state.
  • data/counts_adjusted_for_2010 Contains a csv for each day with the 2020 self response counts mapped to the 2010 census tract geometries. For more information on how this is done have a look at the translate_to_2010_tracts.py script.
  • /data/geo/2020_tracts_with_counts Contains a GeoJSON file per state containing each tract and its most recent response rate.
