Using the Public’s Data to Combat the Public Crisis of Homelessness
Tools for Smarter, Faster, Cheaper Homeless Interventions
On December 20, 2018,Los Angeles County’s Chief Executive Office issued a letter demanding that the Economic Roundtable not release two new screening tools that identify individuals who will become persistently homeless and that it destroy the county data used to develop these tools. The first screening tool uses summary characteristics of previously homeless workers to predict which low-wage workers will become persistently homeless after losing their jobs. The second tool uses summary characteristics of previously homeless young adults to predict which youth receiving public assistance will become persistently homeless in the first three years of adulthood, including youth emancipating from foster care.
Importance of the Screening Tools
Helping people avoid long-term homelessness through early intervention is far less difficult and costly than dealing with the problems that come with persistent homelessness. Homelessness takes a heavy toll on those who experience it, especially on their health. The costs of persistent homelessness are also high for taxpayers. As periods of homelessness persist, problems become more serious and the cost of treating them more expensive.
The problem is that it is not easy to identify those people who are at high risk of becoming persistently homeless so that resources can be targeted toward early interventions that work for them.
The powerful benefit of these new screening tools is that they will enable high-risk individuals to avoid the misery and harm of persistent homelessness by identifying them when they first become homeless, or even before they are homeless, so that they can immediately get the help they need to escape homelessness.
On December 20, 2018, the same day the predictive modeling report was sent to the Chief Executive Office and Department of Public Social Services for review, the county responded by emailed letter, asserting that the Economic Roundtable had made unauthorized use of county data. County staff assert that rather than being public records, this data is controlled by “departmental owners.” The letter does not discuss the data use authorizations granted by the county or the value of the screening tools for combatting homelessness.
Research began with approval of the County Board of Supervisors in 2005. Research to develop the current tools was carried out transparently and collaboratively with county staff, who received multiple briefings and opportunities to provide input during tool development.
The tools were built by applying sophisticated statistical modeling to records provided by the county that have been de-identified to safeguard individual privacy. Both tools predict which individuals are most likely to become persistently homeless, based on de-identified summary characteristics of previously homeless individuals. The tools will be freely available to all users.
The Economic Roundtable’s conclusion is that its use of the data is permitted and that information the public has paid to produce, that has been de-identified to protect the privacy of individuals, and that has been transformed through philanthropic funds and nonprofit effort into tools for combatting homelessness should be used for public benefit.
