RSEI Census data are contained in three tables, Census 90 (data from the 1990 Census), Census 00 (data from the 2000 Census) and Census 10 (data from the 2010 Census). These three tables contain the Census data that has been transposed onto the RSEI model grid. Each Census table is over 600 MB in size when unzipped. 1990 Census data have been provided by Geolytics, Inc.

These population tables are not version-specific.

Census data were last updated in 2012.
