The data is pretty uninteresting and has a lot of duplicate records with slight variations in the street address. SSNs are essentially public data at this point, just freeze your credit.
(should be frozen by default but that's another conversation)

Also, super important, but address history is in the leak, so all those sites that ask you about your address history to authenticate you need to knock it TF off right now.
... SSN has 9 decimal digits, so there are only 1 billion (or even somewhat less) of valid SSNs in the whole universe...
