It might be skewed a little bit since the average person probably lives in a city (or very close) and the average standalone house is probably not found in a city, so the comparisons are a bit misleading. If you look at the price of homes in cities, the multiplier is likely higher than 5.4x. Taking Cambridge, MA as an example (though it's certainly more expensive than average) - median house is ~1.4M in 2018 (probably higher now), and median _household_ income is ~75K USD per year - for Cambridge, giving a multiplier of something like 20x (household income, not counting taxes - not individual)
