So they overestimated the bounceback in New Orleans... or underestimated the original depopulation.
Incidentally, I've spent the whole morning reducing the Louisiana ftp file to where it isn't total information overload anymore.
How did you do that? I couldn't even get the file to load.
Did trying to unzip sort of semi-freeze your computer (unrelated stuff working, if a little on the slow side)? In that case, the answer is simply patience. Bags of it. Oh yeah, I downloaded it first and opened it offline after.
One issue I have is that Open Office has a limit on the number of lines in a document... 65kodd... which is not nearly the end of the document. It goes through the state by CD first, then by legislative district, then by county (or parish in the case of Louisiana)... and the by-county hierarchy goes all the way down to block level (I think) while the earlier ones only go to Tract. Not that I cared even about Tracts. Yeah, anyways that 65k lines is reached, like, a third or a quarter down the by county part. Doing the same thing with Mississippi right now.
