Census Bureau systems were not compromised.
There have been reports of an unsecured 800 gigabyte database, owned by an unidentified party, comprised of over 200 million personal user records including information such as full names, email addresses, dates of birth, and credit ratings.
A website alleges “that much of the data on the main folder might have originated from the United States Census Bureau”. This is false.
The Census Bureau reviewed the sample data and determined that it did not come from the Census Bureau. The initial reports mentioning the Census Bureau also stated that "analysts suspect that the database belonged to a data marketing firm or a credit company.”
