That was the estimate from the University of Chicago in 2021 which has since been actively been disproven by point in time counts of actual homeless people.
“53% of people living in homeless shelters and 40% of unsheltered people were employed, either full or part-time, in the year that people were observed homeless between 2011 – 2018.”
“According to the Los Angeles Homeless Services Authority’s (LAHSA) 2019 Adult Demographic Survey, over 50% of single adults (24 and older) experiencing unsheltered homelessness in Los Angeles County are unemployed (LAHSA, 2019a). Of those unemployed, approximately half reported that they are actively looking for work. The same survey found that 49% of unsheltered adults in family units are unemployed, but a much higher percentage of them (36%) are actively looking for work than single adults. Additionally, 46% of unsheltered adults cited unemployment or a financial reason as a primary reason why they are homeless (LAHSA, 2019a).”
And:
“According to the same survey, about 20% of single adults experiencing unsheltered homelessness in Los Angeles County are working, including full-time, part-time, seasonal, and self-employment compared to about 32% of unsheltered adults in family units (LAHSA, 2019a). Not only are people experiencing homelessness employed at low rates, but evidence shows that those who are employed report very low annual earnings (California Policy Lab, 2020). In Los Angeles County, employed people experiencing homelessness earned an average of just under $10,000 in the year prior to experiencing homelessness (California Policy Lab, 2020).”
