Jury Pool Profile: Jury Selections in Alameda County

We gathered data from few of our recent Alameda County (CA) jury selections. In this post you’ll find helpful information about the most commonly used statistics, like age and education. In a separate post, we cover these same jurors’ key opinions of lawsuits and damages awards.

Age

The majority of Alameda County jurors fall between the ages of 30 and 59 years old. It’s important to remember that the final, seated jurors won’t likely have this exact age profile. The median age of your juror will depend on the type of case and length of trial. In some cases, the seated jury is skewed older because retirees are more able to serve than other, typically younger, jurors.

Marital Status

Almost 60% of the Alameda County jurors are married. This contributes to a higher rate of married jurors seated to decide a case. First of all, there’s more of them. Second, jurors who come from households with two incomes might be better able to serve than jurors who are single, separated, divorced, or widowed.

Education

Education in Alameda County


As shown above, 43.8% (39.3% + 4.5%) of the jurors who showed up to these jury selections have a bachelor’s degree and another 25.4% hold a graduate degree. That means that 69.2% of our jurors had at least a bachelor’s degree. This is markedly higher than the most recent census statistics for Alameda County. Specifically, the 2013-2017 estimations lists 25.7% of county residents as having a bachelor’s and 19% with a graduate degree.

The location of the courthouse is likely the cause of these education statistic disparities. Jurors described in this post, reported to the Alameda County courthouse in Downtown Oakland. Jurors who report to the courthouses in Hayward, Fremont, and San Leandro might have differing levels of education.

Prior Jury Service

Prior jury service in Alameda County

We found that about 22.7% of the jurors summoned to the courthouse had served on at least one jury in their lifetime.

For context, we examined statistics for state courts in California. We found that 2.1% of trials in 2017 were jury trials. The other 97.9% were bench trials. We would probably have more jurors with prior service if the rate of jury trials was not so low.
