Here's a great graph from Mike Norman Economics:
Rental Income is "Rental Income of Persons with Capital Consumption Adjustment" (which you can find in FRED here). What's that? According to the BEA: "It consists of the net income from the rental of tenant-occupied housing by persons, the imputed net income from the housing services of owner-occupied housing, and the royalty income of persons from patents, copyrights, and rights to natural resources."
And, starting in the late 1980s it skyrockets as a percentage of our economy. It declines in the mid-2000s (the BEA explains why here), but is returning with a vengance. (Update: This data includes imputed rents homeowners pay themselves, and that is driving a lot of the increase, and we should emphasize that it makes straightforward analysis more complicated.)
But we are concerned with this impact on real people. What does the rental market look like on the ground, especially for people with high rents? The Joint Center for Housing Studies of Harvard University just released their 2012 State of the Nation's Housing.
(Aside: do we have too many houses? Study: "Given that the number of new homes added in 2002–11 was lower than in any other ten-year period since the early 1970s, it is difficult to argue that overbuilding is dragging down the housing market. Instead, the excess housing supply largely reflects the sharp slowdown in average annual household growth in 2007–11 to just 568,000—less than half the pace in the first half of the 2000s or even the 1.15 million averaged in the late 1990s." This household formation drop is due to the unemployment crisis and "a sharp drop in immigration." There are some good charts that explain this.)
For the purposes of our rentier economy, I want to look at something they emphasize: people burdened by housing expenses. They find that, from 2007 to 2010, there was an increase of 2.3 million households paying more than half of their income for housing (what they define as "severly burdened"); that brings it to a total of 20.2 million. That is no doubt impacted by the unemployment crisis, but this is a longer-term trend too. There was an increase of 4.1 million people paying more than half their income for housing from 2001-2007:
That 20.2 million severly burdened households are equal to 18 percent of all households. 27 percent of renters fall into this severly burdened category, with homeowners roughly half that number.
Who falls into this category? Older people are vunerable, with a rise from 12 percent to 16 percent of 55-64 year olds falling into the severly burdened category from 2007 to 2010. Metropolian areas, especially core cities, are places where this is prevalent. It impacts poorer people the most, with over 60 percent of those making less than $15,000 in this category, and 30 percent of those making between $15 and $30 thousand dollars a year as well. It's negatively correlated with education, with those with a college degree having the lowest rates - so this isn't a matter of young college graduates overpaying to live in a nice city.
Indeed It is worth noting that poor families with children paying more than fifty percent of their income on housing spend less on other essentials. "Among families with children in the bottom expenditure quartile, those with severe housing cost burdens spend about three-fifths as much on food, half as much on clothes, and two-fifths as much on healthcare as those living in affordable housing." No doubt some of these cost burdened households love living where they do, save on transportation and don't mind the spending; others are spending much less on food for their children because they need to spend so much to keep a roof over their heads.
This is what it looks like when working people get squeezed by rents.
