To all my new friends on here: my areas of knowledge are the Cook County property tax system, GIS, and random history stuff.

For Chicago TIF data wonks: you might be surprised to find out that Cook County's TIF distribution calculation method changed this year!!
In the past, current/frozen EAVs were aggregated at the tax code level to determine an area TIF distribution %. Now, this calc occurs at the property level.
