Why are some people called to jury duty repeatedly?

Iloilo Jones (Executive Director of Fully Informed Jury Association) gives expert video advice on: How do I know if I've been summoned for jury duty?; What if I can't make the date on the jury summons?; Why are some people never called for jury duty? and more...

People often get called to jury duty repeatedly because there's a small jury pool, maybe half the people in the town aren't registered voters, maybe a lot of people are excused for other reasons, if you lived in Washington, DC a lot of people are excused because they're federal employees, and so even though it may be a large community, they may have a lot of court cases and a lot of jury trials but a very small jury pool to draw from. And another reason you might be called repeatedly is because you've told the Clerk of Courts that you're retired and you enjoy serving on juries, and you're interested in justice, and they can put you on the volunteer jury list.
