Hello,

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. I would like to inquire about the reason for this missing data. Could you provide any insights into this issue? Thank you very much for your assistance.

Hello,

Hi,

Previsouly, I have been using bucketed_dwell_times ““<5”, “5-10”, “11-20”, “21-60”, “61-120”, “121- 240”, “>240””? In the recent filed I only observe “5-10”, “11-20”, and 61-120", “121-240”, can you please help me learn as the SafeGraph Doc says " * Data delivered from December 2020 onward, including all backfilled historical data, contains the following bins: { “<5”, “5-10”, “11-20”, “21-60”, “61-120”, “121-240”, “>240”} " on the safeGraph document page

Specifically, I have questions about the following columns: visitor_home_cbgs and visitor_daytime_cbgs. I would like to clarify the definitions of the "home city" and "home CBG" fields, as well as understand how these fields are censored.

I’m working with the monthly foot traffic data for the Kansas Metropolitan area, focusing specifically on the variable VISITOR_HOME_CBGS.
