The lowest value I ever see in visitor_home_cbgs is 4 (eg, I never see a Census Block Group with 3 visitors.) Is 4 some kind of threshold, or is there some other reason why this happens?

In the weekly patterns data, there is a column, visitor_home_cbgs, that shows the number of visitors to a POI based on their home Census Block Group. The lowest value I ever see in there is 4 (eg, I never see a Census Block Group with 3 visitors.) Is 4 some kind of threshold, or is there some other reason why this happens? Thanks!

Hi yes, 4 is the lowest number we report. For privacy, we do not report any CBGs with only 1 visitor, and any CBGs with 2-4 visitors are always rounded up to 4 visitors.

See this page for more info.
