While I understand that Hanscom could bring a level of complexity, that
distinction is not relevant in this particular discussion because the CCBC
is not calculating the non-Hanscom population. The benchmarking used the
TOTAL Lincoln population.


The issue at hand is that the town census shows 600 (~40%) more seniors
than the US census for all of Lincoln. Hanscom does not affect that.


More importantly, the Hanscom discussion does not change the fact that the
CCBC is not being forthcoming about sources. The CCBC said, in writing, and
I quote: “The CCBC has used the Town Census numbers for every town, to
ensure full comparability”. That is simply not true. Regardless of Hanscom
or not, the CCBC benchmarking is using different sources for other towns
and not for Lincoln. They used the *lower* numbers for other towns from one
source and the *higher* numbers for Lincoln from a different source. At the
very least, there should have been a caveat explaining this.


I would also note that, given the upward bias of a town census, due to the
methodological issues I describe in my previous post, there is little
reason to believe the ACS is a less accurate population measure.


By using the higher numbers for Lincoln but lower numbers for other towns,
it seems like we’re trying to justify a center bigger than our needs. If we
add this to the fact that the COA refuses to provide attendance data, we
dramatically increase the probability that the town will be building
another building that is way too big for our real needs.
