Missing Data from Advan Dataset
I noticed data that I thought was missing from the Advan datasets. Heads up if you have the same issue -- the GEO IDs are connected to 2010 Census Block Groups, not 2020. Glad I solved this, hope this helps someone else!

MIssing Foot Traffic Data for Certain POIs
I am currently downloading the Advan Research data for 2022–2024 and have noticed that many major airports, such as Cleveland Hopkins International Airport and John Glenn Columbus International Airport, lack the data of visits and visitors from home CBGs for the period between December 2022 and December 2024.

How to Find the Corresponding NAICS Category for Each POI in pass_by
Hello. I am working with pass_by data that contains retail store visitors and visits information without the NAICS code, which makes it challenging to categorize POIs. My current approach to assigning NAICS categories is to leverage Placekey to link pass_by to SafeGraph. Then, I could use Brand Info from SafeGraph to determine the corresponding NAICS codes for each POI in pass_by.
