Improvements made to the 2022 SIPP help identify the type of imputation procedure used on the following variables: class of worker (AJB1_CLWRK-AJB7_CLWRK), industry (AJB1_IND-AJB7_IND, ANJ_IND), and occupation (AJB1_OCC-AJB7_OCC, ANJ_OCC). Specifically, each variable’s imputation status flag was updated to include new values indicating logical imputation, cold-deck imputation, or a combination of imputation types. Refer to the 2022 SIPP Users’ Guide for more information about the imputation status flags and allocation in SIPP data.
