Some 2010 Census Updates

Some geography updates to pass along regarding new US Census data:

  • The Census has released a few 2010 map widgets that you can embed in web pages. One shows population change, density, and apportionment for the whole country at the state level, while the other shows population, race, and Hispanic change for states at the county level. As of this post only four states are ready (LA, MS, NJ, and VA) but they’ll be adding the rest once they’re available.
  • The 2010 TIGER Line Files are starting to be released; they’ve changed the download interface a little bit based on user feedback. Most summary levels / geographic areas are available; some (like ZIP Codes and PUMAs) will be released later this year.
  • They’re also rolling out the new interface for the American Factfinder; currently you can get 2000 Census data, some population estimates, and the 2010 Census data as it becomes available. Other datasets like the American Community Survey and Economic Census will be added over time. Some maps and gov docs librarians have expressed concerned about the change – apparently when you download the data from the new interface the FIPS codes are not “ready to go” for joining to shapefiles; there’s one long geo id that has to be parsed. The other concern is that the 1990 Census won’t be carried over into the new interface at all. The original American Factfinder is slated to come down towards the end of this year.
