When Mayor Eric Adams of New York City announced on Tuesday a major push to remove people with severe, untreated mental illness from the streets, he waded into an issue that has for years been driving policy — and frustrating policymakers — in cities around the United States and the rest of the world.
Here is a snapshot of a few places where the authorities have been trying to recalibrate their support services for homeless people, including those with mental illnesses.
Mental health care for homeless people has been a legal quandary for more than a half-century in California, dating to a national shift toward deinstitutionalization and a 1967 law — signed by Ronald Reagan, then the state’s governor — that was intended to safeguard the civil rights of Californians who were mentally ill.
The state has spent tens of billions of dollars on homelessness, but efforts have been stymied both by neighborhoods that resist construction of shelters and supportive housing and by structural issues that, for example, make cities responsible for housing and sheltering homeless people, but put counties in charge of the public funding required to provide those who are mentally ill with continuing treatment.
A law signed this year by Gov. Gavin Newsom aims to force some severely mentally ill people into court-ordered treatment and housing, but it will only apply to about 12,000 people with schizophrenia and other serious psychotic disorders, not all of them homeless, and will not start until next year.
There are close to 42,000 homeless people in Los Angeles, a majority of them unsheltered, according to recent county data. About a quarter of homeless adults identified as having a serious mental illness, according to the report. Under a county-run program, psychiatrists work in the streets to connect unsheltered mentally ill homeless people to care.
Frustration over the city’s homelessness crisis has reached a boiling point. Officials have banned public camping at dozens of sites, as well as within 500 feet of schools and day care centers. City officials have also become increasingly willing to use police force to clear makeshift campsites, and the newly elected mayor, Karen Bass, has vowed to end them.
In San Francisco, a patchwork of programs offers those who are mentally ill and sleeping on the streets respite, shelter and treatment. But experts say that without enough medical workers or housing, those programs often fall dismally short of the need.
“There just isn’t enough of it,” said Margot Kushel, a physician and the director of the Benioff Homelessness and Housing Initiative, a research group that advises policymakers and is based at the University of California, San Francisco. “Without the housing, it all falls apart.”
In Chicago, homelessness is an endemic problem that has become more visible since the pandemic, particularly as encampments have grown under viaducts near Lake Michigan and in parks throughout the city.
But advocates for the homeless say that they have never heard of city employees — from the police department or elsewhere — sending homeless people to hospitals against their will in the manner that Mr. Adams laid out on Tuesday.
“The police are not looking to involuntarily hospitalize people who are not a danger to others,” said Debbie Pavick, chief clinical officer for Thresholds, a nonprofit behavioral health organization that works with homeless people.
Instead, city employees and nonprofit providers work to connect homeless people with services and housing. Thresholds deploys mobile teams of workers in vans to try to engage the homeless and help them to receive primary health care, mental health treatment and medication, among other services, Ms. Pavick said.
In Portland, concerns about homelessness and safety were at the center of recent campaigns for both local and state offices, and the city has now advanced a contentious plan to ban street camping, hoping eventually to direct people who do not have housing into a series of city-run tent sites.
The city has also moved to get more homeless people into mental health care. The region’s capacity for mental health services has long been strained. Two months ago, three hospital systems sued the state, saying that people who were civilly committed because they were a danger to themselves or others ended up languishing in hospitals for months instead of being placed in long-term treatment, such as at the state psychiatric hospital.
Tina Kotek, a Democrat who recently won the governor’s race, has vowed to pursue policies to build more housing, increase the number of people who work with homeless populations, and expand services for those experiencing a mental health crisis.
In East Asian cities, homelessness tends to be far less common than it is in the United States. But the problem does exist, and in some places it worsened during the pandemic as some of the working poor were unable afford housing in expensive real estate markets.
Hong Kong, a Chinese territory with high rates of inequality, is one of several East Asian cities where homeless people have for years sheltered in plain sight, including at 24-hour McDonald’s restaurants. The number of people registered as “street sleepers” in the territory roughly doubled over a seven-year period, to more than 1,500 last year, according to a government report — slightly more than the reported figure in
