ceprDATA is maintained by the Center for Economic and Policy Research (CEPR) in Washington, DC.

Questions about the CEPR Uniform Data Extracts and this website should be addressed to

ceprdata [at] cepr [dot] net

Please note that the 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.
