One of the reaction threads I saw elsewhere on social media pointed out the response rates for the surveys that come up with these numbers is plummeting--about a decade ago, we had ~85% response rate, now we're done to ~65% response rate. So the initial quality of these numbers is probably getting a lot worse.

I'd suspect better computing helps a lot here.
