I have a couple of questions about the Advan Monthly Patterns - Home Panel Summary.
Historical Real Estate Data from Verisk
I am working with the Verisk property data that Dewey provides. Is there a way to access historical snapshots of the data? As I understand it, the dataset is updated monthly to include new transactions, during which the modelled columns (eg estimated property value) are changed using the information from that months' new transactions. As a result, the dataset you can download via Dewey's API only has the most recent sales price for each property (as previous transactions for that property are overwritten) and older transactions and property value estimates are unavailable. I am interested in having access to both the complete transaction history for properties included in the dataset and the property value estimates over time. Is there a way to access the data in this way?
Spending Pattern Data CUSTOMER_HOME_CITY
I read the description from the Safegraph website (https://docs.safegraph.com/docs/spend#section-customer-information), but it does not tell what the definition of the city is. Thus, I am wondering if anyone could help me with the definition of the CUSTOMER_HOME_CITY (like whether it refers to county, Census Designated Place or something else).

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.
Codebook variable GranteeMailAddressInfoFormat missing?
