The bottom line here is that the Census Bureau has abandoned its previous methods for calculating the subcounty estimates. For 2011, they basically carried the county % change in household population down to the sub-county units (MCDs and places), apparently holding the GQ pop count the same as the 2010 count (most of the time).

In my personal view, coming from a strong MCD state, it would have been better if they had just not done 2011 estimates at all.

This is an interesting article Wendell Cox sent me from a friend of
friend. We all remember when the Census Bureau changed from using
county based estimates to using sub-county estimates in 2009 which are
then used to factor and weight the ACS. I had thought the process of
going from a county to a sub-county was a little more sophisticated but
maybe its not.
