摘要:Suppression of employment records in the US County Business Patterns (CBP) data sets constrains the detail of new methods and recent advances in the analysis of the geographic distribution of firms and employment. Data sets created by imputation procedures can be purchased, but cost often puts them beyond the reach of many research budgets. Fortunately, methods exist whereby researchers can impute suppressed employment records. A comparison of these procedures is necessary to assess the accuracy and flexibility of each.
