It’s less bad than that. 24% in the 2010 census were under 18 and 9.9% were 18–24. I don’t put those under “should be in Congress”, and constitutionally they’re not allowed to be until 25. So it is 13 percentage points out of 66 percentage points — about 20% of the population with 34% of the seats in the house. Senators have to be 30 so the over 65 crowd would be an even greater share there. Given that experience probably gives you _something_, it’s still out of whack but not crazy. All of that said, personally I believe it’s far too skewed and we should have an age cap in Congress.
