@SteveRoth I'm surprised Germany is lower on the graph than US! I don't know whether there's an easy way in FRED, but I think it'll be important to disaggregate non-working-age because child from non-working-age because retired. At a household level, households with kids are unusually high demanders, where households of retirees unusually low. Part of that is just a matter of household size differences, but I think only part. Even on a per-cap basis, I suspect households with kids demand more.
