Analytic Validity

  • Establishments in the SynLBD are fully synthesized using statistical models
  • The SynLBD contains no data from actual establishments
  • Comparison at the establishment level shows SynLBD data differ substantially from the actual data
  • Modeling preserves variable relationships while protecting establishment identity
  • The SynLBD has not been fully validated
    • Relationships between SynLBD variables may not correspond to the relationships in the underlying confidential microdata
    • Validating all possible relationships between SynLBD variables has not been feasible

SynLBD Disclaimer

  • Unless validated, there is no guarantee results from the SynLBD reflect results from the underlying confidential data
  • Researchers are strongly encouraged to request result validation prior to publishing results based on the SynLBD
  • Validation:
    • Is part of an internal Census Bureau process to improve current beta data products
