The share of income people spend on housing has been very stable over 40 years: https://economistwritingeveryday.com/2023/04/26/spending-on-...

The problem isn't so much that housing has gotten expensive. It's that many of the existing places have moved up-market compared to what they were 30-40 years ago. 75 years ago, Scarsdale NY or parts of Long Island were expensive. But Palo Alto was a drab middle class suburb. As the tech economy has boomed, that has driven prices up in Palo Alto for the same reason they were already high in Scarsdale. And now you have to move to Gilroy.

That's a misleading metric for two reasons. First, "people" includes all the people who bought a house decades ago before the prices went up, and correspondingly paid the old prices instead of the current prices. And second, it assumes that if housing becomes more expensive what people all do is pay more for housing rather than being unable to afford it and then having to take a longer commute to access housing they can afford, live with their parents, become homeless, etc., which negatively impact the amount or type of housing they get instead of the amount they pay for it.

Meanwhile between 1984 and today median income increased by ~290% while median new home prices increased by ~425%:

And that's with the gap having reduced a bit in the last couple of years, since home prices have declined slightly since the peak in 2022 while median income continued its usual trend.

Those are fair points. But I think it’s also misleading to look at prices in a fixed location over time, which ignores that places can become relatively more desirable and move upmarket. Yeah, your parents bought a house in Mountain View for cheap. But they were moving to escape high housing prices in the New York or Chicago suburbs where they grew up.

The average FHA mortgage rate in 1984 was 13.2%. Today’s it’s 6.8%. The more expensive house with a cheaper mortgage costs $482 per month less and $173,000 less over the lifetime of the loan.

This is a good point. Also, anytime there is a discussion about inflation, there should be a timeline included.

Both inflation and wages have not gone up uniformly since they started being tracked. We all know the Trump/Biden covid inflation was bad, but by the end of Biden's term wages had mostly caught back up. The second Trump administration's policies reversed that trend.

Housing in particular cratered in some areas during the GFC, but then went wild especially around the covid.

People are moving out of opportunity zones (and you know…losing opportunity) or moving in with roommates to keep the average percentage low.

Feels like such a basic factor to miss for what is supposedly an economists blog. That metric means nothing.

That stability claim is an average for all American households, gathering together high-income households and long-tenure homeowners along with poor renters. But in a K-shaped economy where the wealthy do well and the rest do worse, averaging the two forks of the K hides the hardship of those on the lower fork.

> The net effect of this longer history is that renters today spend much more of their incomes on rent than they did in previous generations. The median renter household in 1960 spent less than a fifth of their income on rent. By 2022, housing costs consumed 31 percent of the median renter’s income. And in inflation-adjusted terms, the median rent is up 75 percent over these six decades while the median renter income has risen by just under 15 percent.

That's not dispositive, though, since it may be that people spend more on rent because they can, i.e. other things have become relatively less expensive.
When real income goes up 15% but rent goes up 75%, people are absorbing a cost, not flaunting their wealth.
The average house is double the size of what it was when the boomers were young.
A lot of people spend more on housing because standards have greatly increased. The average square footage of living space per person has doubled since the 1970s and tripled since the 1950s. A modest home in 2020s was a luxury house in the 50s. Families have gotten smaller and houses have ballooned.

Even when I was a kid in the 1980s I didn't know a single person whose household had multiple bathrooms, a dishwasher, or air conditioning. Not a single one.

Part of the reason why standards have increased is because incomes have increased.

Our 1960s house in one of the richest suburbs in the country (Mclean, VA) was 1,800 square feet. The average new house today is over 2,200.
