Mihn,
If we do any en-mass edit, there are a few things I think we want to consider:
1. Before anything else, we need to make sure it's community approved,
source data and code examined and approved by the community.
Sure. The code isn't ready yet. My e-mail was more of an early-morning
musing. :-)
In particular, I noticed that plenty of POIs have an additional
`census:population` tag that takes the form "1234;2006", where 2006 is a
year and 1234 is a number that usually doesn't match the value in
`population`. I'd like to update `population` and replace
`census:population` with `population:date`, which is far more common
worldwide.
2. I think that in principle this is a good idea, but we'll also
encounter some issues where census data shows that objects:
a. Have moved
b. Have been renamed
c. Are present in one dataset but not the other
We want to flag these for secondary processing (likely manual).
3. I think it'd be nice, if we're doing en mass mechanical edits, to
connect objects to Wikidata
At the moment, boundary relations are mostly linked to Wikipedia, but
unfortunately few POIs are part of those relations. (They'd have a role
of "label", which I think is poorly named, but that's a topic for
another day.) Since they come from TIGER, the boundary relations also
generally have the official census name in `tiger:NAMELSAD`, which would
make step 2 easier.
While it makes sense to keep our own copy of various attributes (like
town/city classifications) in OSM, if we connect the data with
Wikidata, in the future we could pull the data out of Wikidata for
what's classified as what.
They're going to be more inclined to have this kind of data updated
regularly than we are, so this seems like a good way of moving towards
this model, even if today we don't have a way of retrieving the data
from the two datasets and reconciling them.
I'd be okay with #3 being left to a separate task, but I think it
deserves some thought.

It looks like most of the place=city/town/village/hamlet POIs from GNIS are
tagged with 2000 Census populations in the population tag. These population
tags allow renderers to label places with font sizes corresponding to
population, which is a pretty common use case.
I think we should consider a mechanical edit to update these tags to the
2010 Census figures en masse. I've been updating individual places as I edit
them for other reasons, but this tag is most useful when its vintage is
consistent across the board.
