I am trying to understand why the numbers of households in the universe in a 1-year supplemental file for a geographic unit also found in the acs 1 year data file, for what seems to be the exact same question, would be radically different. I am seeing this in estimates for unified school district geographies.
An example: I am comparing B28008-001E, from both the ACS 1 and 5, to K202801-001E from the ACS Supplement, all for 2019. The ACS supplemental estimate of total households is in many cases 1/4 to 1/2 of the ACS 1 and 5 total household numbers, which are usually pretty close, for any given unified school district found in all three datasets. The universe for all three tables, I believe, is households. I think I must be missing something obvious....
Any help understanding what is going on would be greatly appreciated. Thanks!
Can you share links to the data, especially the specific district(s), you're looking at?
