I found a state-by-state table describing in detail how each state reports election information - BUT - that was a 2020 project done by 538.com. It was really quite informative. Here is the link:

projects.fivethirtyeigh…

The closest to it for 2024 seems to be from the National Conference of State Legislatures with table 16:

ncsl.org/elections-and-…

My question:

Where is the information cited above coming from? It's not vote count information from the state(s). It can't be related to the actual ballots. I don't understand how folks know what the gender/age/party breakdown is....

Help?

Thanks.
