It is considered good form to leave a link to the database the graph is based on in the "source:" line. Bad actors could make up this graph out of whole cloth. Twopower332.1938 (talk) 18:58, 13 January 2021 (UTC)

Methodology/source clarification

Can the methodology be clarified here? I want exactly this data (population by individual years of age), but I can't validate that the Census Bureau actually shares this. In looking at the technical reference for the raw, summary level data files, I only see age by ~5yr groupings (20-24, 25-29, ..., 85+). The same is the case with the 2019 county level estimates. By accident I found this page, but now I'm confused in how someone could have created this.

Either a) the specific source should be stated or b) it should be noted that this is an interpolation and not a visualization of raw data. Jwhendy (talk) 17:25, 16 April 2021 (UTC)

I agree, and furthermore it appears to me that the black bars indicating imbalance are plainly counter to the data in the table at the census. If the 2019 table from the U.S. census is correct, the supposed data in this 2020 set cannot be. https://www.census.gov/data/tables/2019/demo/age-and-sex/2019-age-sex-composition.html D. F.

Actually I'm going to have to take that back. Somehow my wires crossed and I was matching the colors to the wrong sex. Anyway, I do agree that the source needs to be declared for the svg itself even if the source is noted in one or more articles that this svg is attached to. D. F.
