This codebook describes the variables contained in the main district court dataset we analyze in the article. To create this dataset, we merged data from the FJC's Integrated Database (IDB) with original data we collected from docket sheets available in each district court's electronic databases.
We will not describe the FJC IDB variables in detail here, and instead refer readers to the comprehensive codebooks available at https://www.fjc.gov/research/idb. For the analysis in this article, we used data from three separate IDB datasets:
- The IDB Civil 1988-present database contains all civil cases filed in U.S. District Courts from 1988, and is available at https://www.fjc.gov/research/idb/interactive/IDB-civil-since-1988.
- The IDB Appeals 1971-2007 database contains all appeals filed in U.S. Courts of Appeals from 1971-2007, and is available at https://www.fjc.gov/research/idb/interactive/IDB-appeals-1971-2007.
- The IDB Appeals 2008-present database contains all appeals filed in U.S. Courts of Appeals from 2008, and is available at https://www.fjc.gov/research/idb/interactive/IDB-appeals-since-2008.
Since our analysis spans from the 1990s to the early 2010s, we merged the two IDB Appeals databases to cover our analysis time period. We preserved PDF copies of the FJC's codebooks for each of these datasets in this repository.
For additional details about the data collection and cleaning process, please see the article and the online appendix.
