Inconsistencies with 2022 Qualified Census Tracts (QCTs)?

[adonak]

I am working with the 2022 QCT dataset and have encountered some inconsistencies between 1.) HUD's list of QCTs, 2.) HUD's locator webmap (https://www.huduser.gov/portal/sadda/sadda_qct.html), and 3.) the downloadable Geocoded dBase file (https://www.huduser.gov/portal/datasets/qct.html). For example, tract # 17031310800 is not on HUD's list of QCTs, nor in the webmap, but does show up in the geocoded dBase file; tract # 17031530600 shows up in geocoded dBase file but not on list.

Has anyone else encountered these or similar issues? Is there a master list or dataset that should be used as main reference?
