Imputing Missing Values in the US Census Bureau's County Business Patterns [01/21] [NBER WP #26632]


Abstract:

The County Business Patterns data published by the US Census Bureau track employment by county and industry from 1946 to the present. Two features of the data limit their usefulness to researchers: (1) employment for the majority of county-industry cells is suppressed to protect confidentiality, and (2) industry classifications change over time. We address both issues. First, we develop a linear programming method that exploits the large set of adding-up constraints implicit in the hierarchical arrangement of the data to impute missing employment. Second, we provide concordances to map all data to a consistent set of industry codes. Finally, we construct a user-friendly, 1975 to 2018 county-level panel that classifies industries according to a consistent set of 2012 NAICS codes in all years.


Updates:

We may periodically update the imputed data. If your enter an email address below we will notify you of such changes.

Important: NB: Census changed the way the CBP data are reported starting in 2017. For these years, Census now perturbs cells with small employment counts, making these data fundamentally different from earlier periods. We do not impute data in those years since there are no missing cells in the data. We nevertheless appended 2017 and 2018 to the panel for completeness. Note that the 2017 and 2018 data are reported on a NAICS2017 basis.
