What is the significance of this?

In the dim past of the sixties you had to register at the draft board--not by mail--and fill out a lengthy questionnaire. Further, the local school district would send a list of graduating seniors to the draft board as a helpful cross-check. Of course, these days you get a social security number at birth in order for your parents to claim you as a deduction, so this "automatic" method is not really a stretch given how automated life has become. You can scoop up more people that way. The same sot of ting happened with jury duty. It used to be the case that juries were chosen from registered voters. Now they are chosen from driver's license records.
