Exactly. There's so much stuff like that going on it's hard to know where to begin with these people. For example, demographics. If you have a large young population and a large elderly population you will have a median income pushed lower than when your demographics skew middle aged. Also, when you have large immigration influx, that forces down your median income as a percentage for the whole population, even if the people who were there before the influx are doing considerably better in real dollar terms. Or if retirees are doing part-time "fun" work for small amounts of pay, when they wouldn't have been 50 years ago, that'll force down median income since they're not competing for higher wages. It goes on and on.
