Mara, I share in your frustration. I have run into the same issue trying to get block level detail on population in households by age, and also hit the wall trying to subtract out GQ's by age. In addition, Units in Structure at the block level would be a huge asset to planners. Block groups are too large and don't aggregate to zones. We are probably going to take block group level proportions and apply them to block data and then sum to zones. With single family & multi-family we can at least overlay land use information and estimate that way.

Kevin Byrnes GWRC From: ctpp-news-bounces(a)chrispy.net [mailto:ctpp-news-bounces(a)chrispy.net] On Behalf Of mkaminowitz(a)baltometro.org Sent: Wednesday, August 29, 2012 4:16 PM To: ctpp-news(a)chrispy.net Subject: [CTPP] detailed age (block level) for population in quarters I have a request for detailed 2010 age data by block for the population in households (aka excluding group quarters). This data is available in SF1 and SF2 at the tract level but not block. It has to be blocks because I need to aggregate up to TAZ, and our TAZ's split tract and block group boundaries. Has anyone come across this data or found a way of estimating it? Group quarters also does not have detailed age groups so we can't just subtract.
