Multnomah County [Oregon] Jury Project, 1973-1976 (ICPSR 9030)

Principal Investigator(s): Grofman, Bernard


The Multnomah County, Oregon, Jury Project was conducted as part of the Modeling Jury Decision Project funded by the National Science Foundation. These data represent a census of 32 jury panels that served from July 1973 through March 1976 in the Fourth Circuit Court in Multnomah County (Portland), Oregon. Information was obtained for both six-member and twelve-member juries. Data were collected from official court records, monthly juror panel summaries, and self-administered juror demographic data sheets. Information collected includes members of the jury, their votes, the final verdict, the type of case, the name of the judge, and the amount of time taken by the jury to arrive at a decision, as well as each juror's age, occupation, years of residence in Oregon, educational background, family information, and information on past juries and trials they were involved in. The data include both individual-level juror and aggregate jury case data, with information on 6,657 jurors and 1,159 trials.
