Thanks Liang for sharing the slides, much appreciated,very interesting
presentation on a proposed metholodology for using larger area ACS
estimates (themselves with a fairly large margin of error, as we know)
to synthesize to PUMAs, which are themselves large area geography.
However no margins of error are addressed that I can see in the
presentation, though the last slide has as "next steps" an item that
proposes inquiry into census block groups and census tracts. One
potential issue is where do the controls for the small-area data come
from if we are somehow coming up with the controls themselves, and then
synthesizing cross-tabs from those controls.
Among other things, margins of errors are something to keep in mind for
