The Census Bureau has created demonstration tables to illustrate how the new differential privacy methodology for disclosure avoidance can be applied to produce CBP estimates.  The tables show estimates of the number of establishments, number of employees, first-quarter payroll, and annual payroll across geographic, industry, legal form of organization, and employment size levels. The input data for the demonstration tables are a set of synthetic microdata created solely from previously published CBP results.  This approach ensures that existing disclosure avoidance safeguards are not compromised by the publication of the demonstration tables. The demonstration tables also include summary statistics of the uncertainty introduced by the new differential privacy methodology and comparison with the uncertainty introduced by the current disclosure avoidance methodology. Â
There are two types of tables: Basic and Research.
Basic Tables include:
Research Tables include:
We invite comments on these demonstration tables, including use cases (examples of how CBP data are used) and whether the new methodology affects these use cases (including whether the amount of noise shown in the demonstration tables would prevent or change any analyses for those use cases).Â
