CBO's Model to Adjust for Survey Underreporting of Receipt and Income From Selected Means-Tested Transfer Programs

This repository contains data, computer code, and documentation (the 'package') that are being made available by the Congressional Budget Office to allow researchers to replicate CBO's adjustments for underreporting of receipt and benefit amounts from selected means-tested transfer programs in data sets from the Annual Social and Economic Supplement (ASEC) of the U.S. Census Bureau's Current Population Survey (CPS).

For a description of CBO's method for imputing transfer receipt, see Bilal Habib, How CBO Adjusts for Survey Underreporting of Transfer Income in Its Distributional Analyses, Working Paper 2018-07 (Congressional Budget Office, July 2018), www.cbo.gov/publication/54234.

The imputations are available for four of the largest means-tested transfer programs:

  • Medicaid and the Children's Health Insurance Program (CHIP),
  • The Supplemental Nutrition Assistance Program (SNAP),
  • Supplemental Security Income (SSI), and
  • Federal housing assistance.

The imputations can be merged with the CPS ASEC files from 1980 to 2019. Those files represent information for calendar years 1979 to 2018. See the section called "Merging CBO's Means-Tested Transfer Imputations With CPS ASEC Data Sets" in the docs\data_contents.md file for more information on how to merge the outputs of this package with CPS ASEC data sets.

NOTE:

Researchers interested in using CBO's imputations for their own research should note that these imputations were designed specifically for CBO's analyses of the distribution of household income, which primarily group households into income quintiles for the entire civilian noninstitutionalized population captured by the CPS sampling frame.

These imputations should not be used for state-level analyses, causal analyses, or policy simulations.

How to Run the Code

The code was written and tested using Stata/IC 14.2 for Windows (64-bit x86-64), although it may be compatible with previous versions of that program. The documentation of the programs included in the package assumes that the user already has some familiarity with Stata. (Further information about Stata can be found at https://www.stata.com.)

See the docs\algorithm_description.md file for information on how the algorithm works.

To run the programs:

  1. Open the main Stata do file: source_code\impute_means_tested_transfers_MAIN.do

  2. In the USER INPUT section of that file, uncomment line 27 and enter the directory path of the source_code directory on your local drive.

  3. Execute the code. Run times will vary, but it should take approximately 10 minutes to run on a typical machine.

  4. When execution is complete, a new set of output files will have been saved in the outputs\data and outputs\diagnostics directories.

    See the docs\data_contents.md file for details about the contents of those output files.
