Jury duty is a wonderful thing

In Louisiana, they pull jury duty from drivers licenses, not voter registrations.

My Mom never registered to vote and regularly got called by Jefferson Parish. My wife never registered and got called in St. Tammany. Then said 'eff it' and finally registered to vote.

They really pull the names from annual residency listings in all states.

They only way they can get that information is if its offered. Generally voter registration is the form most people offer the information to the government to compile these lists. The information can be obtained through the RMV, can also be obtained through home owner records. But its most often gathered annually through voter registration.

The state doesn't know where you reside unless you offer that information
