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
I was able to connect from France, it's for people living in the US, look like you can search for people and there'd be aggregated information scrapped from god knows where. I checked a few (not really famous) people I knew of and it seems they have some accurate information.
LinkedIn doesn't have my Social Security number. It doesn't have a list of my bank accounts and credit cards. So, more people, but less damaging information.
the data sets are more valuable when they're concentrated, so the leak of your address, voter registration, and SSN is now tied to your employment history and education
