SafeGraph Global Spending Patterns: Income and Generalizability
Hello, I am working with SafeGraph Spend Patterns POI data, and I have a couple of questions.
Duplicate Visit Counts Across Different Placekeys in Foot Traffic Data
Using the Weekly Patterns - Foot Traffic - Full Historical Data, I noticed that several rows have identical values for raw_visit_count, raw_visitor_count, and origin_home_cbg, as well as the visitor count within origin_home_cbg, even though these locations have different placekey values. I checked their parent_placekey, and while some of them share the same parent, others do not. Additionally, I examined whether all child_placekey values under the same parent_placekey had matching raw_visit_count, raw_visitor_count, and origin_home_cbg, but that wasn't always the case.

Consumer address history database.
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?
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!
representativeness of Advan data
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?
