Maybe that means API access is one of the line-item things that could be cut when the budget isn't properly funded. But the data itself, including current datasets (which have been downloadable via bulk FTP for awhile) [0] should be pretty stable. After all, the Census is a function directly mandated by the Constitution.

The outgoing director doesn't seem worried.. from your link, when asked if he was worried about there being a leadership vacuum after his departure:
> (laughs) No, the Census is much more than the director
Yes, the Census is more than its leader, but losing its longtime leader and seemingly not having anyone new (there is a new acting director, IIRC) in place this close to the next census seems worrying.
