NHGIS Releases Standardized Tables for 2000 & 2010 Census

Comparing Census data from one decade the next can be difficult since boundaries  and variables can change. Trying to figure out those differences can be time consuming and sometimes frustrating. To help make this easier, NHGIS recently released 65 time series tables standardizing 2000 & 2010 100% count variables to the 2010 Census boundaries for ten geographic levels including tracts, block groups and 5 digit zip code tabulation areas (ZCTAs).

The tables are marked with a TS from within the Topic filter

NHGIS topic filter

Available standardized tables are listed in the Time Series Tables tab, and labeled Standardized to 2010 under the Geographic Integration column.


More information on time tables produced by the NHGIS can be found in the Data Documentation section, including both the geographically standardized tables as well as nominally integrated tables. The page includes methodology, and a PDF containing the complete list of variables within the time series datasets.

Worth A Read

It might seem quiet around the DSSC this week as we gear up for the fall semester, but it’s the perfect time to catch up on summer reading. Here are a few interesting data stories that have come across our radar in recent days:

  • Nathan Yau of Flowing Data made a Statistical Atlas in R, using 2010 census data and an 1874 design aesthetic.
  • Ramiro Gómez provides directions in matplotlib to make a surprisingly evocative map of the UK, using the locations of pubs.
  • LMGTDFY, Let Me Get That Data For You, searches .gov websites to find out what data is publicly available for download.

Got a data project in mind?  Stop by the DSSC, 1pm to 5pm, Monday to Friday to explore what’s possible and cool off from this heat!
