Mapping Shapefiles (Tiger) to CBGs in Advan Neighborhood Patterns

Questions & Help
1

What are the years used for the Census Block Group Shapefile (Tiger/Line) data in the Advan Neighborhood Patterns?

I am trying to map the CBGs to shapefile data from 2019 -2023 and I wanted to know what version of the shapefiles were used as the CBG borders. A post two years go states that 2016 is used for all geometries, and the safegraph current documentation states that 2010-2019 geometries are still used for all years even though there was re-districting in 2020 and they provide geometries for 2020-2029.

I have not been able to find any information if Advan has started to use shapefiles besides 2016 for the CBG specifications?

Advan uses 2018 CBGs (which are based on the 2010-2019 boundaries). Let me know if this helps or if I can answer any more questions!

Thank you for the reply! Do you know where/if this is documented?
