Alameda consistently uses the federal definition of homelessness. It is the Bay Area's third most populous county and in back to back census years it has set records for the increase in the percentage of homeless. The 2019 total tops 8,000 for the first time. That's a 42.5% increase from the 2017 amount, and nearly double the number of homeless from the 2015 census.
CONTRA COSTA COUNTY
Contra Costa and Alameda are neighboring counties and reported a nearly identical percent increase in the number of homeless people, 43 percent, between 2017 and 2019. There are now 2,295 homeless people reported in Contra Costa County. While it's a significant increase from 2017, this is the second lowest homeless population total since 2007. Contra Costa is one of five Bay Area counties that have occasionally varied the definition of homeless from the federal standard. Contra Costa now only reports people who are "actively homeless in our system of care". The county no longer includes data from school districts.
The number of homeless in Marin county dropped seven percent between 2017 and 2019. There was also a significant drop in the number of people identified as chronic homelessness.
Marin has varied both its method of conducting the census and the definition of homelessness over the years. In 2017, Marin switched solely to the federal definition.
Napa is the Bay Area's smallest county by population and has the smallest homeless population. It has consistently used the federal definition in reporting.
SAN FRANCISCO COUNTY
Beginning in 2013, San Francisco varied its definition of homeless for the census. Up until then, the county had consistently used the federal definition. In 2017, San Francisco reported the highest number of homeless of any county in the Bay Area. In 2019, that leading spot went to Santa Clara County, even though San Francisco reported a 17 percent increase in its homeless population, compared to the federal total from 2017. The total homeless population rose above eight thousand for the first time.
SAN MATEO COUNTY
This is one of five Bay Area counties to occasionally vary the definition of homelessness for the purposes of the census. "For the local report we utilize local context regarding categorizing and including programs that serve some people experiencing homelessness," says Michelle Durand, of the San Mateo County Human Services Agency. Starting in 2015, San Mateo chose to use only the federal definition of homelessness.
SANTA CLARA COUNTY
The Bay Area's most populous county had maintained a fairly steady homeless population since 2007, but 2019 is a different story. The homeless population now approaches 10,000. The total increased 31 percent from 2017. More than 6,000 of the homeless live in the city of San Jose. Santa Clara county has consistently used the federal definition of homelessness for its reporting.
This is one of the few Bay Area counties to record a decrease in the number of overall homeless between 2017 and 2019, with a six percent decline.
Beginning in 2015, Solano county has used the federal definition of homelessness. The county was not able to provide information about what definition was used for the census prior to 2015.
Sonoma county has seen the most dramatic changes in homeless population of any county in the Bay Area, but the numbers need some context.
In 2007, Sonoma County recorded 1,314 homeless people - a count that the Homeless Services Manager, Jenny Abramson, believes to be inaccurate. The county changed its counting method in 2009, and the homeless population - on paper - more than doubled to 3,247. Abramson says, "Counts beginning in 2009 are far more reflective of the reality in Sonoma County." The homeless population climbed again in 2011, which the county believes was due to the foreclosure crisis and the 2008 recession. Decreases in the homeless population began in 2013 and continued in 2015 and 2017, when the county reported a homeless population of 2,835, a 13-percent decline from 2009.
In Sonoma, there are minor differences between county data and federal data due to errors in reporting.
The federal government, through the Department of Housing and Urban Development, requires counties to conduct a census of the local homeless population every two years to be eligible for federal funding. These "Point-in-Time Counts" are held across the country on a single night in late January every odd-numbered year. The federal government uses the following definition of homelessness:
An individual or family living in a supervised publicly or privately operated shelter designated to provide temporary living arrangement (including congregate shelters, transitional housing, and hotels and motels paid for by charitable organizations or by federal, state, or local government programs for low-income individuals), or an individual or family with a primary nighttime residence that is a public or private place not designed for or ordinarily used as a regular sleeping accommodation for human beings, including a car, park, abandoned building, bus or train station, airport, or camping ground.
In the Bay Area, five counties - Contra Costa, Marin, San Francisco, San Mateo, and Sonoma - have sometimes used a broader definition of homelessness. For example, a county may include people staying in jails, hospitals and rehabilitation facilities who have no permanent residence, or people who are "couchsurfing", staying with family or friends. When there is a difference between the federal and county numbers, ABC7 News has chosen to use the county data in our reporting because it better reflects the local assessment of the homeless situation. However, we will present data from both sources when appropriate to give greater context.
