3 years ago Confirmed that this problem is for several dates, and also applies to borough aggregations. For example:
-- Check for differences between sector and subsector visits by boro

Example: For 6/30/20, the sector file contains 179 visits for sector 72, ZIP code 10001 in MN. The subsector file contains 1992 visits for subsector 722 for that ZIP code.
