RAND HRS Detailed Imputations File 2018 (V1), supported by NIA and SSA

The RAND HRS Detailed Imputations File contains the component and ownership variables for all waves that are used in the income, wealth, and medical expenditures summary measures found in the RAND HRS Longitudinal File. It is distributed as a companion file to the RAND HRS Longitudinal File, and is especially useful for those who require more detail than that found in the RAND HRS Longitudinal File.

The method used to develop these imputations is described in the RAND HRS Detailed Imputations File Codebook [PDF]. Each original income, wealth, and medical expenditure component is imputed separately, and the components are summed to create the summary measures found in the RAND HRS Longitudinal File (e.g., total household income, total wealth, total out-of-pocket medical expenditures). The original components can vary from wave to wave, and are combined when appropriate to provide consistency across waves.

The RAND HRS Detailed Imputations File 2018 (V1) includes fourteen waves of Core Interview data across sixteen survey years (1992, 1993, 1994, 1995, and biennially 1996—2018) as well as Exit Interview data (medical expenditures only) across twelve survey years (1995, and biennially 1996–2016); 2018 Exit Interview data will be included in the next release of the RAND HRS Detailed Imputations File (2018, V2).

Before doing so, however, we kindly request that users first consult the documentation that accompanies our data products, as we have found that our responses often point users to specific sections of the documentation that provide further detail on the variables mentioned in the users’ queries.

In addition, we recommend that users become familiar with some of the information provided on the HRS website, such as the HRS questionnaires and codebooks for the key variables under study.

We have also found the concordance tool extremely useful to help find available variables across waves:
