I'm not sure of the license situation with any of the NYC.gov
datasets. I've gotten different answers from different people I've
talked to. Some people in some offices say that it's fine as long as
we take certain steps, others say it's not, and others have different
I'm working to get some authoritative data on this.
While I'm generally not a big fan of imports, administrative boundries
are hard to do in another way, and as Richard Welty points out, it's
generally a good thing to replace these nodes with true polygons, and
then we can also use data sources to fill in population tags.

Indeed that is confusing. Off the top of my head, I see two simple solutions:
1. We tag the areas as counties, but use the "common names" as the
primary name, and these official names as alt_name.
2. We create a new administrative relation that has the same geometry
as the county.
I would lean towards the first, as it means less data and more clarification.
