Who lives here, and what they pay
Population, income, rent and housing age for one county, as the Census publishes them. The one layer here that describes the people rather than the buildings.
A row here is a whole county. For the same measures around one address, use the census tract file — it resolves to the tract your parcel is in.

What the rows look like
10 real rows from this file, spread evenly across it rather than taken off the top — every file here is written in some order, so its first rows are never a fair sample of it. These are the default columns, which is what the download button hands over.

Where it comes from
U.S. Census Bureau, American Community Survey
This source does not stamp the day it was published, so we cannot honestly date our copy of it and will not guess. The period the records themselves cover is on the system card.
What this layer cannot answer is stated in full on the system card — read it before quoting a figure.

Point an AI at it
Every file carries its own source, its capture date and the layer's own warnings in the header, so a model reading one gets the caveats with the numbers rather than the numbers alone. Paste this at an assistant that can fetch a URL:

Everything above the header row is provenance and limits. Read it first,
then answer using only what the rows support.
llms.txt describes the whole warehouse the same way — what each dataset holds, which counties it really covers, and what it cannot answer.
