Recently Recovered Data
Historic data from thousands of tapes were recovered before the Census Bureau’s Unisys mainframe computer was decommissioned in 2010. Most of these data still need to be developed for research use.
Occupying 336 square feet, the Unisys Clearpath IX 4400 and 6 tape drives were purchased by the Census Bureau in 1995.

Recovery of Historical U.S. Census Bureau Microdata: Success to Date
(Excerpt from 2009 CES Annual Report)
Federal Statistical Research Data Centers (RDCs) are U.S. Census Bureau facilities, staffed by a Census Bureau employee, which meet all physical and computer security requirements for access to restricted–use data. At RDCs, qualified researchers with approved projects receive restricted access to select non–public statistical system data.
