At this point I've basically accepted that all my info will be found on sites like fastpeoplesearch.com and that anything I tell any company (or I guess in this case, govt too) will eventually be leaked, correlated, and used against me.
names and relations to family members and all their phones and addresses
previous addresses
a lot of it is collected from voter registration data (so your party affilition can be gathered as well)
I was royally pissed when I moved into a new home and literally a day after I signed up for internet service with Spectrum cable I got spam calls that know what state I'm in and my new home address is up online before I ever get around to updating my ID etc so I assume my data was sold immediately by them
