We are researching human mobility and have calculated the visitor rate for each CBG in Erie County using the formula: Visitor Rate = Visitors / Number of Devices.

Hi
I am trying to work with the Consumer address history database.
I have some questions regarding the dataset's representativeness. What does ODDATE represent? Should the EFFDATE of an individual's last recorded address match the ODDATE? Does this mean the individual continues living at the address with the most recent EFFDATE?

Hi,

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!

I'm trying to understand the representativeness of Advan data. What percentage of U.S. cellphones does it capture at a given point in time? Does this coverage percentage fluctuate over time, and if so, what factors influence these changes?

Hello,

Hi,

I'm currently working on Builty building permit data and I have a couple questions:

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.
