LOS ANGELES (AP) -- The nation's homeless population increased this year for the first time since 2010, driven by a surge in the number of people living on the streets in Los Angeles and other West Coast cities.
The U.S. Department of Housing and Urban Development released its annual Point in Time count Wednesday, a report that showed nearly 554,000 homeless people across the country during local tallies conducted in January. That figure is up nearly 1 percent from 2016.
Of that total, 193,000 people had no access to nightly shelter and instead were staying in vehicles, tents, the streets and other places considered uninhabitable. The unsheltered figure is up by more than 9 percent compared to two years ago.
Increases are higher in several West Coast cities, where the explosion in homelessness has prompted at least 10 city and county governments to declare states of emergency since 2015.
City officials, homeless advocates and those living on the streets point to a main culprit: the region's booming economy .
Rents have soared beyond affordability for many lower-wage workers who until just a just few years ago could typically find a place to stay. Now, even a temporary setback can be enough to leave them out on the streets.
"A lot of people in America don't realize they might be two checks, three checks, four checks away from being homeless," said Thomas Butler Jr., who stays in a carefully organized tent near a freeway ramp in downtown Los Angeles.
Butler said he was in transitional housing — a type of program that prepares people for permanent homes — for a while but mostly has lived on the streets for the past couple of years.
The numbers in the report back up what many people in California, Oregon and Washington have been experiencing in their communities: encampments sprouting along freeways and rivers; local governments struggling to come up with money for long-term solutions; conflicts over whether to crack down on street camping and even feeding the homeless.
The most alarming consequence of the West Coast homeless explosion is a deadly hepatitis A outbreak that has affected Los Angeles, Santa Cruz and San Diego, the popular tourist destination in a county where more than 5,600 people now live on the streets or in their cars. The disease is spread through a liver-damaging virus that lives in feces.
The outbreak prompted California officials to declare a state of emergency in October.
The HUD report underscores the severity of the problem along the West Coast.
While the overall homeless population in California, Oregon and Washington grew by 14 percent over the past two years, the part of that population considered unsheltered climbed 23 percent to 108,000. That is in part due a shortage of affordable housing.
In booming Seattle, for example, the HUD report shows the unsheltered population grew by 44 percent over two years to nearly 5,500.
The homeless service area that includes most of Los Angeles County, the epicenter of the crisis, saw its total homeless count top 55,000 people, up by more than 13,000 from 2016. Four out of every five homeless individuals there are considered unsheltered, leaving tens of thousands of people with no place to sleep other than the streets or parks.
By comparison, while New York City's homeless population grew to more than 76,000, only about 5 percent are considered unsheltered thanks to a system that can get people a cot under a roof immediately.
In the West Coast states, the surge in homelessness has become part of the fabric of daily life.
The Monty, a bar in the Westlake neighborhood near downtown Los Angeles, usually doesn't open until 8 p.m. Partner and general manager Corey Allen said that's because a nearby shelter requires people staying there to be in the building by 7. Waiting until after that to open means the streets outside are calmer.
Allen said the homeless have come into his bar to bathe in the restroom wash basins, and employees have developed a strategy for stopping people from coming in to panhandle among customers.
Seventy-eight-year-old Theodore Neubauer sees the other side of it. Neubauer says he served in Vietnam but now lives in a tent in downtown Los Angeles. He is surrounded by thriving business and entertainment districts, and new apartments that are attracting scores of young people to the heart of the nation's second most populous city.
"Well, there's a million-dollar view," he said.
Helping those like Neubauer is a top policy priority and political issue in Los Angeles.
Since last year, voters in the city and Los Angeles County have passed a pair of tax-boosting ballot initiatives to raise an expected $4.7 billion over the next decade for affordable housing and services for the homeless. HUD Secretary Ben Carson praised the region for dealing with the issue and not relying solely on the federal government.
"We need to move a little bit away from the concept that only the government can solve the problem," he said.
But Mayor Eric Garcetti said that insufficient federal funding for affordable housing and anti-homelessness programs are part of the reason for the city's current crisis.
"Los Angeles' homelessness crisis was not created in a vacuum, and it cannot be solved by L.A. alone," Garcetti said in a statement.
Excluding the Los Angeles region, total homelessness nationwide would have been down by about 1.5 percent compared with 2016.
The California counties of Sacramento, which includes the state capital, and Alameda, which is home to Oakland, also had one-year increases of more than 1,000 homeless people.
In contrast, the HUD report showed a long-running decline in homelessness continuing in most other regions. Nationally, the overall homeless number was down by 13 percent since 2010 and the unsheltered number has dropped by 17 percent over that seven-year span, although some changes in methodology and definitions over the years can affect comparisons.
Places where the numbers went down included Atlanta, Philadelphia, Miami, the Denver area and Hawaii, which declared a statewide homelessness emergency in 2015.
The homeless point-in-time survey is based on counts at shelters and on the streets. While imperfect, it attempts to represent how many people are homeless at a given time. Those who work regularly with the homeless say it is certainly an undercount, although many advocates and officials believe it correctly identifies trend lines.
The report is submitted to Congress and used by government agencies as a factor in distributing money for programs designed to help the homeless.
