@Max_KatzBarber @AshleaTullipan I wondered that too! Apparently it's not a major problem, at least when considering large areas. It is a problem if you start drawing conclusions about, and identifying, institutions like prisons, schools, work-places, etc.
"WWBE ethics bible" doesn't provide enough guidance for this, and other issues like: where do we draw the line, are we accounting for the population we're measuring, etc? https://t.co/OH5zuERdBe #ACSSanDiego
