Veraset's census years and geolocation details

Hi,

I have two questions regarding the Veraset data.

According to this website (https://docs.deweydata.io/docs/faqs-veraset#what-year-census-does-veraset-use-in-their-data), Veraset uses the 2010-2020 Census data. Could you please clarify the exact period (both in UTC and local time) when Veraset began using data from the 2020 Census? The cutoff date is not clearly specified, so I'm not sure if my matching of Veraset and Census information is correct.

Also, it seems that the 2019 Veraset data does not include geometry information for POIs (i.e., no longitude and latitude provided). I attempted to match the POIs in Veraset data with SafeGraph's POI geometry data, but I ran into a problem as Veraset used safegraph_place_id as the identifier for POIs in 2019, while SafeGraph has switched to placekey since 2021. Do you have any suggestions on how I might obtain the geolocation information for POIs in the 2019 Veraset data?

Thank you!
