Question About Health Center POI Data Trends (2021-2023)
We are using mobility and foot traffic data to identify the number of unique POIs for certain business types. While comparing the number of health centers across different years using the same NAICS code, we noticed a significant increase from 2021 to 2023.
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.

Recent Open Census Data in the US
Hello, does anyone know whereto find the most recent years of open census data (5-year ACS) at the Census Block Group (CBG) level for the US available for download?

Possible measurement error in number of transactions in 2022 for Starbucks?
Is there any documented measurement error in Starbucks's transaction count in 2022? I noticed that 99.5% of all Starbucks stores in the data set had less than 3000 monthly transactions. However, some stores, like the one attached in Exhibit, had 10 times the number of transactions in only one month in 2022, which is surprising. I have a list of several other such Starbucks stores.
