I have know others to use similar approaches. However, one question that remains, which is
more of a research question is which ACS series to use. 2006 to 2010 or 2008 to 2012? I
can make good arguments to go either way.

I cannot provide guidance, but you might find our recent experience helpful. We have used
2010 SF1 data for households by size and ACS 5 year (2006-2010) shares for income. We
chose this approach to be consistent with 2006-2010 ACS PUMS data that we also use, and in
the absence of other information.

Subject: [CTPP] Census 2010 vs 5-year ACS for TAZs
Ive gotten started on our long range transportation plan, and one area we have an issue
with is Census data. We've got 2010 Census data for our population and household
counts, but we will also need the 5-year ACS data of number of households by household
size by household income. We would prefer to use 2010 population counts for the base year
of the model so we've decided there are two options. We could use the 5-year ACS data
for our base model year population and household counts, but that doesn't create a
true picture of 2010. The other option is we could mix datasets and proportionately apply
characteristics of the 5-year ACS data to the 2010 counts. Can anyone give us some
guidance needing to use both datasets on the same project?
