Housing the homeless

Homelessness isn’t new in the United States. It has existed since the country’s founding, ebbing and flowing over the years. What’s new is the large number of homeless Americans. Beginning in the late 1970s and early 1980s, there was an observable increase in the number of Americans asking for handouts, sleeping in public places, wandering the streets with their possessions in shopping carts, and searching for food or cans in garbage bins. For the first time in our history, homelessness became a truly public phenomenon. Indeed, it was around this time that the term “homeless” was coined.

As Christopher Jencks notes, “The spread of homelessness disturbed middle class and well-to-do Americans for both personal and political reasons. The faces of the homeless often suggest depths of despair that we would rather not imagine, much less confront in the flesh. Daily contact with the homeless also raises troubling questions about our moral obligations to strangers. Politically, the spread of homelessness suggests that something has gone fundamentally wrong with America’s economic and social institutions.”1

According to the best available estimate, about half a million Americans are homeless on any given night. Careful counting began only in 2007, but this number is similar to estimates from the mid-1980s and mid-1990s.2 About four-fifths are adults, and one-fifth are children. The National Coalition for the Homeless estimates that about 2 million Americans are homeless at some point during a year, though it isn’t clear how accurate that estimate is.3

The homeless are approximately 0.2% of the US population, or two out of every 1,000 persons. Since 2007 this share has decreased, as figure 1 suggests.

What caused the rise in homelessness in America? What could we do to help?

WHAT CAUSED THE SURGE IN HOMELESSNESS IN THE EARLY 1980s?

The most careful statistical and ethnographic studies suggest the rise in homelessness beginning in the 1980s had multiple causes.4

Structural developments

Several structural trends placed increasing numbers of Americans at risk of becoming homeless.

Deinstitutionalization. In 1955, about 550,000 patients resided in state and county mental hospitals. By 1980, that figure had shrunk to 140,000, a 75% drop. Deinstitutionalization has been widely blamed as the main cause of rising homelessness. Yet it’s at best only a partial explanation. Nearly 90% of the decline in mental hospital residency had occurred by 1975. The best estimates put the share of the homeless with serious mental health problems in the 1980s and 1990s at around one-third. That’s not a trivial share, but neither is it an enormous one. Furthermore, even for individuals for whom deinstitutionalization was a precipitant of homelessness, its effect was likely modified or mediated by other factors.

Decline in the stock of low-income housing and inflation in the cost of housing. Between 1973 and 1979, more than 90% of the nation’s housing units renting for $200 or less per month disappeared from the housing market. Many of these were single-room occupancy (SRO) units which had long housed the nation’s poorest individuals. In Austin, Texas, for example, the median rent skyrocketed from $150 per month in 1976 to $450 in 1985.5 In addition, under the Reagan and Bush administrations, new government-subsidized low-income housing units decreased significantly.

Rising unemployment and stagnant pay. The US unemployment rate grew from 5% in 1973 to 7% during the late 1970s to 10% in 1982 and 1983. Studies of homelessness consistently find that unemployment is a precipitant of homelessness for many individuals. And stagnant wages for those in the lower half of the pay distribution meant that even for those with work, the ability to afford housing and feed a family was no longer a given.6

Decline in the real value of welfare benefits. In the 1970s and 1980s, the inflation-adjusted value of social assistance benefits (Aid to Families with Dependent Children, or AFDC) decreased.7

Individual-level factors

The number of individuals who find themselves living on the economic margins is considerably greater than the number who are homeless at the same moment. Thus, we have to turn to individual-level factors to understand why some vulnerable people become homeless while others do not.

Disabilities or pathologies. A fairly large share (probably more than two-thirds) of homeless individuals have some disability or pathology — mental illness, alcoholism or drug abuse, poor physical health, a criminal record — that makes them less able than the average person to survive without help. In some cases, though, this is a result of homelessness, rather than its cause.

Lack of family support. David Snow and Leon Anderson interviewed and spent time with 168 homeless men and women (primarily men) in Austin, Texas between 1984 and 1986. About two-thirds of these men attributed their situation in part to family problems or an inability or unwillingness of family members to offer them temporary support. One-quarter of them grew up in orphanages or foster homes.

Bad luck. For more than a few homeless individuals, an event of bad luck — a car accident or breakdown, stolen belongings, a work injury — provides the initial or final push onto the streets.

Choice. Some homeless persons are in that position by choice. Most studies suggest that this accounts for a small percentage.

HOW DOES THE US COMPARE TO OTHER RICH DEMOCRATIC NATIONS?

Despite the country’s affluence, Americans at the bottom of the distribution have relatively low incomes.8 And government assistance with housing costs is scarce.9 We might therefore expect more homelessness in the United States than in other rich democratic nations.

Comparable data on homelessness are available for only a small number of countries. They are shown in figure 2. The homeless share is higher in the US than in a number of these nations, but France and Austria have similar levels and Canada’s is a good bit higher.

HOW CAN WE HELP?

Being homeless doesn’t automatically mean being without shelter. A host of public and nonprofit agencies exist across the country to provide shelter to persons who lack a home. As figure 3 indicates, about two-thirds of homeless persons are in some type of indoor shelter when the count is done in January each year.

Figure 4 shows the number of available beds per homeless person. Since careful counting began in 2007, this number has always equaled or exceeded the number of homeless Americans, and the ratio has increased steadily, reaching more than 1.6 by 2018. The reason a third of homeless persons aren’t in shelters is partly spatial mismatch: the beds may not be where the people are. In other cases it may be because people have overstayed their eligibility at the available shelter, because they’ve been barred for violating rules, or because they voluntarily forgo an indoor bed.

Given the rise in the number of available beds (figure 4), why hasn’t the share of homeless persons who have shelter decreased (figure 3)? The reason seems to be that the bed increase has come almost entirely in the form of “permanent” housing, as we see in figure 5.

According to the National Alliance to End Homelessness, “Moving more people into permanent housing options, as opposed to temporary beds, has become a recognized best practice.”10 Here is one summary of the evidence that underpins this view11:

“The solution, it seems, lies not in publicly sheltering the homeless for sustained periods but in ensuring that they quickly secure their own places to live.

This approach was first applied to the chronically homeless, who made up 16 percent of all cases in 2012. These individuals almost always have disabilities such as mental or physical health problems or addictions. As a result, they fare poorly in conventional homeless programs, which may require compliance with the rules of an emergency shelter — such as sobriety — before allowing them entrance to a transitional shelter. Further compliance, including treatment for substance abuse, for instance, may be required before they can qualify for permanent housing support.

The alternative strategy places the chronically homeless directly into permanent housing while also connecting them to services to address their other challenges. Most will need this support, at government expense, for life. Yet such comprehensive assistance is probably cheaper than leaving the chronically homeless on the streets, because they often end up in hospitals, detox centers or jails, all on the taxpayer’s dime. Those services cost the public $2,897 per individual per month, according to one study in Los Angeles County, versus $605 for supportive housing….

New approaches are also being applied to the situationally homeless — families and individuals who’ve slipped into homelessness because of misfortune such as a job loss, personal turmoil or a costly illness. Traditionally, they have gone from an emergency shelter to a transitional one, where they might spend months working to save the money for moving expenses, a deposit and the first month’s rent on an apartment. Under a new program, authorities instead grant that money upfront, getting the household out of shelter quickly or sometimes even preventing a lapse into homelessness.

Once assisted, people tended to stay housed. Numerous studies showed that only about 3 percent of households served were homeless again within 12 months. Plus, costs per household were much less. A report on efforts in seven states concluded that rapidly rehousing a family costs $5,775 on average, compared with $18,776 for an average stay in transitional housing.”

The sharp increase in permanent housing for homeless Americans is likely the main reason why homelessness has decreased steadily since 2007 (figure 1).

How do we know the chief cause of declining homelessness isn’t the improving economy? One reason is that figure 1 above shows there was no sharp rise in homelessness as the economy moved from healthy in 2007 and 2008 to weak in 2009 and 2010.12 Another reason is that financial vulnerability to homelessness doesn’t seem to have decreased since 2007. Figure 6 shows one measure of this: the share of American renters who spend more than 50% of their income on rent. This share has hovered around 2% of the population throughout this period.

SUMMARY

Approximately 0.2% of Americans are homeless on any given night. The causes are a mix of structural and individual factors. Homelessness increased sharply in the 1980s. Since the mid-2000s it has fallen, largely due to a shift toward provision of permanent housing for homeless persons.
