San Mateo County’s homelessness population increased by 21% since 2017 with a total number of 1,512 residents experiencing homelessness. While the number of residents living in transitional and emergency shelters remained almost the same, the number of unsheltered residents increased significantly. This increase is mirrored across the Bay Area, and counties like Alameda, who are seeing homeless numbers as high as 8,000 are trying new ways to reduce homelessness. In Oakland, a partnership spearheaded by  Kaiser Permanente aims to house 525 aging homeless residents with chronic diseases and provide the needed wrap-up services to reduce readmission rates. Hospitals are increasingly recognizing the role that housing places as a determinant of good health and aligning their investments to house the most vulnerable.
