Homelessness in Ventura County:
An analysis of the service use and costs
of persistent homelessness, FY2017 & FY2018
Homelessness is on the rise in Ventura County. After almost a decade of steady decline, Ventura's 2019 point-in-time survey counted 1,669 men, women, and children experiencing homelessness, a fifty percent increase from 2017. This trend continued into 2020, with the January point-in-time count growing by an additional 4.4% to 1,743 adults and children experiencing homelessness.
Among this population, service use is often concentrated disproportionately among a relative minority of people who face acute and persistent challenges. In 2019, Ventura County partnered with the cities of Oxnard and Ventura to engage Social Finance in better understanding the service use and resulting costs of supporting this population.
The analysis, highlighted in this interactive report, integrated data from 13 County and City departments to track homeless programs, law enforcement, healthcare and behavioral health delivery, emergency transit, and other programs.
Defining the high-utilizing population
Determining whether or not an individual is experiencing homelessness is challenging through administrative data alone. Some individuals experiencing homelessness do not access government services, while many who are accessing services are not experiencing homelessness. No single data source provides a definitive demarcation.
By joining together data from across Ventura's public services, Social Finance developed a method to estimate the service use of people who are very likely experiencing homelessness and are frequent users of emergency services. Scroll down to explore.
Social Finance began with a data set of 8,999 individuals with at least three interactions with any service tracked through the Homeless Management Information System during FY17 FY17 is July 2016 - June 2017. & FY18. FY18 is July 2017 - June 2018.
Among these 8,999 individuals, 2,519 were flagged as very likely to be
Defined as meeting one of fifteen key service code descriptions including:
At Risk/Homeless Housing, Related Assistance Programs, Emergency Shelter, Homeless Courts, Homeless Drop-in Centers, Alcohol Use Related Recovery Homes/Halfway Houses, Homeless Employment Programs, Homeless Motel Vouchers, Homeless Transportation Programs, Homelessness Prevention Programs, Housing/Shelter, Private Mail Services, Public Showers/Baths, Runaway/Youth Shelters, Street Outreach Program, Transitional Housing/Shelter
Of these, 541 individuals were experiencing homelessness over two or more years. Defined as meeting one of the indicative service codes in both FY17 & FY18.
And of these individuals experiencing longer-term homelessness, 140 individuals were classified as high-utilizing. We defined the high-utilizing population as the top 25% as measured by cost.
The interactive graph below displays the historical costs of the 140 highest-utilizing people experiencing homelessness, on average, across FY17 & FY18.
Each number on the x-axis represents an individual. Individuals are ordered from highest cost to lowest cost.
The y-axis displays average annual costs The average annual cost for each individual is calculated by adding costs across FY17 and FY18 and then dividing by two. for each individual.
The colors in the graph correspond to the type of service utilized.

This kind of aggregated analysis can be valuable to policy-making, but it’s only one part of the puzzle. The stories of the people whose lives are highlighted in these data are essential. We recognize the limitations of a purely numerical perspective, and recommend taking the time to hear directly from people experiencing homelessness.
One small contribution toward the goal of recognizing unique journeys through the homeless system of care is to understand how different people from the analysis interacted with public systems. Below, explore the journeys of four of these individuals.

When we examine the data by quartile, cost drivers vary.
High-utilizing individuals are more likely than the broader homeless population to interact with multiple agencies. The Venn diagram below explores service usage overlap among the top-three utilized services: healthcare, behavioral health, and jail.
The costs of persistent homelessness are high - not only to the County, but to the health and wellbeing of individuals experiencing homelessness as well. This analysis attempts to measure the dollars and cents associated with the status quo—with the hopes that it can inform future discussions about the most effective use of public funding to end homelessness.
