Paul,
        Having been a Census-taker myself, I know the process.
Actually, it would be very unusual for an adress checker (done
one year before the Census itself) to change a street name. We
were given printouts that were our guide as we checked addresses.
If something didn't match, such as if a new apartment building
was constructured, we had to do a special form.
I never had a street-name change (Santa Monica is well-established),
but I imagine someone doing a suburban area might have some.
Now, supposedly we got our information from someone who actually
lives there. But, that means trusting that the person you are talking
to that day knows what they are talking about. So, there's lots of
room for error.
In 2010, we were instructed to add a GPS point near the front door
of each dwelling unit or apartment building. However, we were not
given guidance on how close to stand. I suspect that is one reason
why we have so many zig-zag streets. :-)

ÃÂ ÃÂ ÃÂ ÃÂ After my inquiries about
the rash of named driveways in Campbell County,
Virginia--these are driveways that end of with
the name of the street they intersect--I
finally gotÃÂ a reply from the county GIs
director (pasted in below). He says
inequivocally that it is a TIGER issue, not a
local one. Probably no surprise. I know opinions vary on TIGER.
That's not a giant surprise.ÃÂ And it's not
so much that opinions on TIGER vary so much as
the quality of TIGER itself is highly
variable.ÃÂ I've seen places where TIGER was
amazing and there wasn't much to do other than
add speed limits and turn lanes.ÃÂ But
Portland, Oregon comes to mind as an area where
it was pretty obvious that they digitized
someone's hand-drawn map, which was drawn on a
napkin with a fine-tip ballpoint pen in the
rain, and was like trying to get a cat to
cooperate with being rubbed backwards to sanitize.
Ã
ÃÂ ÃÂ ÃÂ ÃÂ He also add a couple of
data souces, his own county and the state of Virginia, that could be useful.
ÃÂ ÃÂ ÃÂ ÃÂ I sent this to TIGER and
asked that they update us on any fixes for this.
Ã
Given the inconsistency of TIGER data, I would not be surprised
if no automated effort will be ever attempted to deal with that dataset
ever again.
That said, there are tilesets out there that show TIGER data that thas
a newer name or geometry than what OSM has, though this itself has its
pitfalls. I've noticed a tendency for such datasets to false-positive
on a name because OklaDOT renamed something and whatever Census-
taker mapped it in TIGER kept the old name.
