We do plan to keep Lookup online for the foreseable future, though it could disapear at any time. P12 and P13 deal with data that is fairly detailed. The fact is the Lookup crew is not sure why it wasn't done, but we do know that this is intentional. Possible reasons is that it could disclose personal data which Census is forbidden to do for 72 years, or it could be that the data is too voluminous and would have made the data sets way to large. Regardless, P12 and P13 for stf1 are not on the CDs, so it isn't in Lookup.
Many inquiries are for family members.
This law also states that we cannot disseminate any individual information that have been collected for 72 years. Violating this provision is a criminal offense. Therefore we cannot give out any individual data.
