Variable Table

Notes that provide the details of harmonization and any comparability issues of which users should be aware are available for every variable by clicking on the variable name. Each note is also available in PDF through the link "View as PDF."

In addition, for most variables users will also see links to:

  1. Download EXCEL File: Translation Tables which map variable metadata (label, universe, question text, response categories) and project notes from all relevant survey years. This information was used to create the Comparability Notes.
  2. Download Stata source code: Stata .do files containing source code which created the harmonized variables from individual survey variables.

Additional information about imputation flags, weighting, and other issues can be found in the IFSS User Guide.

Contraceptive calendar variables can be added to the extract at the end of he extraction process or downloaded from the Data and Documentation page. Comparability notes for the 6 calendar variables can be accessed by selecting Variable Group: Contraceptive Calendar.

Please contact us at netmail@icpsr.umich.edu with any questions about the data.
