Unfortunately, the two researchers who created the SIPP extracts for CEPR no longer work here, and none of us who work here have experience with the SIPP. So, for the time being, we will not be updating our SIPP extracts, and are unable to field questions about the SIPP. Please visit the SIPP page at the National Bureau of Economic Research to find extraction programs and further information on the SIPP. The SIPP page at the Census Bureau should also be useful.
CEPR Uniform Extracts of the SIPP are available to download in Stata 8/9 format, for 1990-2008 panels.
Our Stata programs are the major source for information on our extracts. For the SIPP, the programs can be found here. Our Stata code show the changes we made to the original raw SIPP variables in order to create our extract.
The latest version of the CEPR SIPP Uniform Extracts is Version 2.1.7 :
Each compressed file is around 100-300Mb; uncompressed, each SIPP panel contains Stata data files of around 1-4Gb. If you don’t want to download the data, you can replicate the CEPR SIPP Uniform Extracts by using our programs. For data in other formats, please contact us.
