The SIPP–SSA–IRS Synthetic Beta File is accessible to users in its current form since 2010. Interested users can request an account by following links at https://www.vrdc.cornell.edu/sds/. Applications are judged solely on feasibility (i.e. the necessary variables are on the SSB). After projects are approved by the Census Bureau, researchers will be given accounts on the Synthetic Data Server. Users can submit validation requests, following certain rules, outlined on the Census Bureau’s website. Deviations from the guidelines may be possible with prior approval of the Census Bureau, but are typically only granted if specialized software is needed (other than SAS or Stata), and only if said software also exists already on Census Bureau computing systems. Between 2010 and 2016, over one hundred users requested access to the server, using a succession of continuously improved datasets.
