This codebook documents version 4.1 of the SIPP Synthetic Beta (SSB).
The SSB is a set of files containing individual-level data synthesized
from linked survey and administrative data. The SSB is produced by
the US Census Bureau as part of a joint project with the Social Security
Administration (SSA), and the Internal Revenue Service (IRS). The
goal of the project is to make some of the benefits of linked survey
and administrative data available to researchers outside of restricted‐access
Census Bureau facilities in a manner that protects the confidentiality
of the underlying data.
This document was posted by the U.S. Census Bureau. No known curated archive exists.
