I'd say a significant majority of people do, but inadvertently. Only 8 states don't require USSSS registration before obtaining an ID/driver's license and would automatically register (CA, CT, IN, NE, OR, VT, WA, WY), and of those, Washington and Indiana still automatically register unless there is an explicit opt out. It's also a requirement for consideration of financial aid or in-state tuition for college, so many public universities won't allow application without proof of USSSS registration first and also helpfully auto-register on application or during enrollment. My experience in CA is public high school would refuse to even award a high school diploma if you're 18 by graduation and didn't register and would also auto-register on your behalf if no explicit opt out was given. Funnily enough, mine registered me in the 30 days _before_ I turned 18.
