The HUD/USPS dataset may also be of use. The program is on
hold but data is available up to Sept. 2010.
I think it goes down to the tract level, and looks at vacancy
in terms of whether or not they have been collecting their
mail.

The problem is that vacancy status is determined, in the
end game, by the enumerator who goes out there and looks at the building/unit.
Some units that are really occupied will be declared vacant because the
occupants, who may be squatters or illegal immigrants, are hiding from the
census. Sometimes there's a fine line between a vacant unit and one which should
be taken out of the stock as unlivable. I have the general impression that in
2010 the tendency here was toward vacant, whereas in 2000 and 1990 the tendency
was toward removing it from the stock. I doubt that there's any way to prove
this one way or the other.
Adam - does your ordinance also cover
vacant apartments in multi-unit buildings?
Bottom line - the census is
not clearly definitive on this point. Its mission is to count people, not vacant
units.

Hello everyone.
I am in need of information regarding how the Census
Bureau determines the status of vacant structures. Our city has a vacant
structure ordinance in place. This ordinance dictates that property
owners register their buildings with the city planning department. How
does the Census determine which structures are vacant? Thanks for the
help.
