The Supreme Court Database is used in a number of different ways. Some users of the Supreme Court Database create extensions to the data, tethering against the SCDB ID. The Primary Investigators sometimes prepare research reports using the data. This section of the website contains contributed, complementary data sets that can be used to extend the scope of the foundational data and reports that rely on these data.

If you have questions or comments about the available code please email the author. If you have code you would like to contribute please contact us.

    Many studies of voting by Supreme Court justices use measures of ideology. This dataset contains the ideology and qualifications scores developed by Segal and Cover (APSR, 1989) and the ideology scores developed by Martin and Quinn (PA, 2002) along with justice identifiers to easily merge the scores onto the Justice Centered Data. Please consult the documentation for details.
