Alameda County Homeless Mortality Report
Calendar Year 2022
Executive Summary
A responsible and just community must work to be closely aware of the deaths of all its
members, strive to learn from those deaths and implement policies and practices to reduce
preventable deaths, support equitable and appropriate end-of-life services, and work to reduce
the harm that preventable deaths create for families, friends, caregivers, and the community. A
just community will review places and moments of death to ensure that people do not die
alone and experience death in as peaceful a manner as possible.
The Alameda County Health Care Services Agency’s Health Care for the Homeless (ACHCH)
program and the Public Health Department’s Community Assessment, Planning, and Evaluation
(CAPE) unit carried out Alameda County’s first-ever homeless mortality report in 2020 and carry
out this report on an annual basis.
This report is based on identifying homeless deaths through data matching across County
homeless services utilization lists, community and clinical reporters, and California
Comprehensive Death File (CCDF) records in the California Vital Records Business Information
System.
Because of the methods used, Alameda County’s homeless death numbers will appear higher
than those of other localities that rely solely on medical examiner/coroner’s reports of
homeless deaths.
Key Findings in the 2022 Alameda County Homeless Mortality Report
In 2022, 351 persons were determined to have died in homelessness in Alameda County. Also,
there were 266 deaths of persons with a recent experience of homelessness but were housed
at the time of death. Another 95 deaths were among persons with a recent history of
homelessness but whose housing status at the time of death was not possible to determine.

The number of annual homeless deaths grew considerably between 2018 and 2020 and
remained at a very high level in 2022. Between 2018 and 2022, 1,506 Alameda County residents
died while experiencing homelessness:

CY 2022 Homeless Mortality Overview
Mean age of death of people
experiencing homelessness:
52.2 Years
Mortality rate: The age-adjusted mortality rate for people experiencing homelessness in
Alameda County in 2022 was 2,983 homeless deaths per 100,000, or 5.4 times that of the
general population of Alameda County. For all causes of death, mortality rates are many times
higher for people experiencing homelessness than the general population.
Unattended deaths: Seventy-two percent (253 of 351) of homeless deaths took place outside
of a medical setting (e.g., hospital or nursing facility), instead occurring outdoors; on streets or
sidewalks; in shelters, encampments, vehicles; other’s residences; and other locations. Forty-
two percent of homeless acute/chronic disease-related deaths (65 out of 154) occurred in
“unattended” settings.
Disparities by race/ethnicity and gender: African American/Black persons represent 44% of
homeless deaths, compared to 19% of general population deaths and 11% of the general
population. Men represent 80% of homeless deaths, compared to 53% of general population
deaths. The mean age at death among people experiencing homelessness is 52.2 years
compared to 73.9 years in the general population, a difference of almost 22 years.

Characteristics of Homeless 2022 Deaths
Drug overdose: 31.3% of homeless deaths in
2022 (110) were directly due to unintentional
and unknown intent drug overdoses (hereafter
called ‘drug overdoses’). The number of drug
overdoses among people experiencing
homelessness continued to rise sharply. Seventy-
seven percent of drug overdose deaths took
place in outdoor settings. People experiencing
homelessness have 43.9 times the drug overdose
death rate of the general population.
• Acute/chronic medical conditions: Forty-four
percent of the homeless deaths in 2022 (154) were due to acute/chronic medical
conditions, led by heart and cardiovascular disease and followed by cancer, diabetes, liver
disease, cerebrovascular disease, COVID-19, respiratory disease, and others. 42.2% of
acute/chronic disease-related deaths were unattended, occurring outside of
medical/clinical settings.
• Accidental injuries (excluding drug overdose) accounted for 33 (9.4%) homeless deaths, the
large majority being pedestrians and cyclists hit by automobiles, followed by falls and struck
by trains. Homeless pedestrians/bicyclists are 26.6 times more likely to be killed by cars
than the general population.
• Homicide accounted for 22 (6.3%) deaths of people experiencing homelessness, mostly due
to shootings and stabbings taking place in the street and outdoors. The death rate for
homicide among people experiencing homelessness is 20.6 times that of the general
population.
• Suicide: Ten people experiencing homelessness took their own lives in 2022, a rate 11.7
times that of the general population.
• Shelter residents: Fifty persons were known to be residing in homeless shelters at the time
of death in 2022. Fifty-six percent of them died of acute/chronic diseases, 26% of drug
overdoses, and the remaining by suicide, accident, and homicide. The percentage of shelter
overdoses increased from 17% in 2021 to 26% in 2022.
• Encampments: At least 25 people died in homeless encampments in 2022. Two-thirds of
them died of drug overdoses, 16% of acute/chronic diseases, 8% of homicide, and the
remaining died of other causes including fire and exposure, with 8% of the causes of death
undetermined by coroner.
• Vehicle dwellers: Some 23 persons were reported as having died inside their vehicle of
residence in 2022. This is in addition to those who might have died in facilities but lived in
their vehicle. Of them, 32% died of drug overdoses, 45% of acute/chronic disease and the
remainder by homicide and accident.
• COVID-19: COVID-19 was the cause of death for six persons experiencing homelessness in
2021. Two shelter residents died of COVID-19 in 2022. The COVID-19 death rate for people
experiencing homelessness was 3.2 times that of the general population.

• Hospice-eligible deaths: In a review of the homeless deaths, ACHCH determined that at
least 61 (17.4%) of the homeless deaths appeared to be “hospice-eligible” or “expected”
deaths due to terminal illness. Of these 61 deaths, 31% were unattended—taking place in
shelters, outdoors, vehicles, and other settings. Of the 42 hospital or nursing facility
hospice-eligible deaths, more review is needed to determine if the decedents received
appropriate palliative or hospice care services.

* A mortality rate ratio of 1.0 indicates equal mortality rates between the homeless and the general population. A
rate ratio greater than 1.0 indicates a higher rate of mortality among people experiencing homelessness. For
example, people experiencing homelessness have a rate of drug overdose death 43.9 times higher than the
general population.

Next Steps
This Alameda County homeless mortality report focuses on data and accurately enumerates
deaths among our unhoused communities. To advance this work, in 2023 the County of
Alameda convened a Homeless Mortality Review Team to further analyze these data, inform
the development of future mortality reports and the coming dashboards, and make
recommendations to reduce preventable deaths among people experiencing homelessness.
Beginning in early 2024, instead of publishing a detailed annual homeless mortality report and
analysis, Alameda County Health Care for the Homeless (ACHCH) and Community Assessment,
Planning, and Evaluation (CAPE) staff will produce an online, public-facing, user-driven, and
filterable data dashboard for homeless mortality data which will allow providers and the public
to analyze countywide homeless mortality data. For updates, go to
https://www.achch.org/alameda-county-homeless-mortality.html.
Specific homeless mortality data questions or requests can be sent to achch@acgov.org. Press
inquiries should be directed to hcsa-pio@acgov.org.
