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
