PATTERNS AND DETERMINANTS OF PUBLIC SHELTER UTILIZATION AMONG HOMELESS ADULTS IN NEW-YORK-CITY AND PHILADELPHIA

Administrative data on public shelter utilization among homeless adult s from New York City (1987-1994) and Philadelphia (1991-1994) are anal yzed to identify the relative proportion of shelter users by length of star and rate of readmission, and to identify the characteristics tha t predict an exit from shelter Survival analyses reveal that half of a dult shelter users will stay fewer than 45 days over a two-year period (combined stays), and that approximately one half of men and one thir d of women will experience a readmission within two years of the first admission. Results also document the size and relative resource consu mption of a long-term sheltered population, finding that 18.2 percent of New York shelter users stay 180 days or more in their first year, c onsuming 53.4 percent of the system days for first-time shelter users. Discrete-time logistic hazard regression analyses reveal that, in gen eral, being older of black race, having a substance abuse or mental he alth problem, or having a physical disability, significantly reduces t he likelihood of exiting shelter In both cities, people entering shelt er in later years are staying longer although individuals have shorter episodes on subsequent admissions. The implications of this study for the analysis and management of emergency shelter system utilization a re discussed.
