One consequence of the economic crisis is that the rate of home ownership has been slipping, as the chart below shows (via Calculated Risk). 
A
growing number of economists and urbanists question whether the United
States has put too much emphasis on homeownership and over-invested in
housing. Ever since the Great Depression, America has generously
subsidized homeownership through the tax code and by other means.
Housing does take up a significant share of U.S. investment
comparatively speaking; and, in some regions, real estate, housing, and
construction made up a huge share of the local economy, as high as 25
to 30 percent at the height of the bubble, bigger than education,
health-care, government, or manufacturing. I've argued elsewhere that
the two American dreams - of homeownership and of unfettered economic
mobility - may be in conflict, as homeownership, especially in
downturns like today, impedes mobility and makes it harder for
individuals to move to work and the labor market on the whole to
adjust.
The benefits versus costs of homeownership is an important debate. On the pro-side, Joel Kotkin makes the case for homeownership in his recent Forbes column. Stephen Slivinski provides a thorough review (via Tyler Cowen) of the downsides of what he calls America's homeownership bias.
Simply put, Americans may have overinvested in housing. This has been a worry of economists for a while. It's a concern based on what they see when they compare the rates of return - profit per dollar invested - for a variety of capital types ... "When you observe that the measurable rates of return are different across the sectors," said the Dallas Fed study author, Lori Taylor of Texas A&M University, "you either have to conclude that there are substantial unmeasured returns across the sectors or you have to conclude that society would be better off with a reallocation of resources." These unmeasured benefits would have to be very large - at least $3,600 per homeowner in America - for the investment imbalance to be explained ...
Robert Shiller, an economist at Yale University and an expert on national housing markets, has estimated that "from 1890 through 1990, the return on residential real estate was just about zero after inflation." Throw in the costs of maintenance of the property and it's easy to see how renting could certainly be cheaper than owning, even if you include the tax advantages. Yet the opportunity cost of those home investments - the foregone investment opportunities elsewhere - go largely unseen ...
Being tied down to a house tends to make people less likely to leave an area in which employment prospects are deteriorating ...A seminal study by British economist Andrew Oswald of the University of Warwick traced the link between unemployment and homeownership. Oswald looked at the United States, the United Kingdom, France, Italy, and Sweden between 1960 and 1996 and discovered that, on average, a 10 percentage point increase in homeownership tended to correlate with a 2 percentage point increase in the unemployment rate.
Recent studies of European data discover that you don't see these sorts of correlations in areas with higher concentrations of renters. Renters are simply more able and willing to move away when their community hits the economic skids. In addition, workers who aren't likely to move from a specific location might create frictions in the markets for labor skills. It's a cost to the economy when people live in an area in which their skills are no longer valued. But there is a potential personal cost too: The overall welfare of that worker may suffer. Homeownership also tends to contribute to adverse political incentives. Incumbent homeowners have an interest in keeping their property values high and have been shown statistically to have a bias in favor of land-use regulations. These restrictions limit the number of houses that can be built in any geographic area and, consequently, keep housing inventory low and property values artificially inflated.
It appears that the crisis is causing a shift from homeownership to rental, as the graph below (also from Calculated Risk)
shows. This trend may end up being a good thing for certain homeowners
and for the flexibility of the U.S. economy as a whole.
One
thing we know about crises is they frequently bring about significant
changes in the system of housing tenure. The Great Depression and New
Deal innovations in housing finance and housing policy, plus the
post-war boom and infrastructure building, brought a massive shift
toward single family homeownership. My hunch is it's time for new
hybrid forms of housing tenure which mix the benefits of ownership with
the flexibility of renting.

The first chart's y axis is labeled "Percent Owner Owned U.S.".
Is it supposed to show what percentage of homes are owned by their occupants, or of families who own their own home, or ... ?
It's hard to take statistics seriously when they aren't labelled meaningfully.
The link to Calculated Risk just gives a bigger version of the chart, it doesn't point to anything that would explain it or put it in context.
So apparently, it's better for the economic growth of the country as a whole if the citizenry are, on average, rootless and without equity. Of course! How better to ensure that the top 1% can maintain their exquisite, manicured lawns, filled with topiary and gazebos and brimming with generations of spoiled, trust-funded progeny, than to enjoy an ample supply of hapless laborers who can be shipped like so much livestock from region to region, without extended families or reliable homesteads from which to draw solidarity or spirit. The myth of the nuclear family and the rise of hypercapitalism has led to endemic decay of the strength of the middle class. Analysis of the above chart will likely only contribute further to the slide, as those in positions to do so will suggest changes and trends that discourage ownership of anything in favor of usurious temporary arrangements (which only result in more profit for the financial giant and more debt for the little people.)
I'm glad people are beginning to acknowledge (perhaps without even realizing it) that the stability and quality of American life are not necessarily served by unregulated and unquestioned financial rapine.
Re: John C.
Your perspective on this issue is backwards. We give away $115 billion every year in tax deductions to homeowners. This huge giveaway goes to people who already have houses, not to helping those who are "rootless and without equity". Like most tax deductions, the bulk of the benefit is going to the already well-off. As Stephen Slivinski clearly detailed, the "rootless" are exactly the people who should NOT be buying a house, at least until they come across a stable job.
The goal should be affordable housing for everyone. The mortgage interest tax deduction is an extremely inefficient tool to achieve that end, especially with its absurdly-high $100,000 annual limit. And giving federally-subsidized mortgages to even the most financially-insecure applicant is a disastrous policy as well. Most people are better off renting.
