First, it interpolates the 2010 Asian population from 2010 block groups to 2020 block groups. The methodology and code for that can be found here. The block-group-to-block-group crosswalk is at crosswalk/crosswalk.csv. The final CSV that compares 2010 demographics data to 2020 demographics data on the same block group geography is at data/data.csv.
Next, it joins it with block group geographies and Letters plan geographies. The resulting GeoJSON is at mapping/output.geojson.
Some exploratory mapping of that data lives on Observable.
The Makefile directs all the data downloading and transformation.
