Geoff,

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

 

Hello Everyone,

 

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?

 

Thank you,

Geoff Olson
