It us acquired under the LUCA program. You have to go through a form of clearance for confidential data to access LUCA data and it is not public domain. I do not have that clearance, so my understanding of it is limited. Basically, the Census sends each county there current records and the county reviews/updates it. There are no direct penalties, but not participating leaves you on the outside for grant money and significantly increases the risk of undercount. As well, since so many commercial services integrate decennial tiger data, nit correct the Census records can create other problems for a county down the road. But to repeat, LUCA data is confidential(?) and never released to the public. -Brett Lord-Castillo
