Did anyone notice on last week's announcement of the release of SF2
(combined LF and SF data) that the "rule of 100" applies? So, even though
the "population-/minority count-pony" has long since passed through the
paddock gate and is out in the far pasture growing fat on sweet grasses
(down to the block level!), the outlook for the long-form data, such as
income and poverty (for Environmental Justice concerns), looks a bit grim.
Are other groups outside of transportation, such as health, human services,
or education, voicing any concerns about losing the fine geo-level information?
SF2 is NOT combined long form and short form data. It is short form data
iterated for the smaller and more detailed race groups, such as individual
Indian tribes, is at the tract level only, and is subject to suppression of
the count of the group in the tract is too small.
The first long-form data will be SF3, coming out on the ubiquitous "flow
basis" beginning in June or thereabouts. I think users will be pleased
with the tables, some of which go to block group and some to tract.
Let's not sound the death knell too soon!
