Search Tips for Variables

  • Enter words or strings that are likely to appear in a variable name, label, question, and value labels:

    Presidential election

    will return variables dealing with all presidential elections

    Presidential election Obama

    will return only variables dealing with the 2008 and 2012 presidential elections

  • Use quotes to search for specific phrases:

    "life satisfaction" "minority rights" "community programs"
  • The minus sign may be used to remove certain types of results:

    "Presidential debate" -"Bill Clinton"

    will eliminate the debates from 1992 and 1996 in which Clinton participated.

  • A Boolean "and" is implied in the search.

  • The search automatically does stemming (more info); there's no need to type in an asterisk. It's also case-insensitive.

  • A fielded search is also available.

Compare Variables

The Social Science Variables Database (SSVD) enables users to examine and compare variables and questions across studies or series. The SSVD currently includes over 500,000 NAHDAP-related variables, representing the majority of NAHDAP's holdings that have quantitative data described in statistical syntax.

The SSVD only includes a subset of our collection. For a comprehensive search of all datasets, use our main data search which indexes all of the documentation available for our studies, including the variable descriptions.
