I'm researching to see if PUMAs contain no less than 65,000 people or no less than 100,000. I can find references for both. Which is it?
Thank you,
Lorna
PUMAs appear in both the ACS PUMS and the ACS summary tables.ACS summary tables are provided for many different summary levels: counties, census tracts, ZIP Code Tabulation Areas, and many others, incl…
Perhaps the confusion is around the 65,000 limit as one of the criteria for inclusion for the one-year ACS.
PUMAs are created to have at least 100,000 people -- sometimes much more.
The smallest PUMA is Elkhart County (Outside Elkhart City)--Goshen City, Indiana, with100,044. The largest is NYC-Queens Community…
Thank you Jnigrine for responding. Yes, confusion. I see in the 1yr ACS that the small counties are left out of the tables (but included in the 5yr). I'm still unsure when the 100,000 threshold is used and when the 65,000 is used.
The smallest PUMA is Elkhart County (Outside Elkhart City)--Goshen City, Indiana, with100,044. The largest is NYC-Queens Community District 7--Flushing, Murray Hill, & Whitestone, New York, with 270,930
Ignore the 65,000 threshold. That is for ACS 1-year reporting, not for PUMA definitions.
Thanks Glenn, I get the 1000,000 is for PUMAs. I use the ACS data (PUMS) all of the time. How does the 65,000 play into that. If everything is at least 100,000 then when would there be anything smaller?
Hi - The 65,000 does not play into PUMS; it relates only to tables. PUMS' smallest units are PUMAs.
It doesn't play into anything. The 65,000 is not relevant to PUMAs. It's for the ACS. Two different things.
