Inpatient Hospitalizations and Emergency Department Visits for Persons Experiencing Homelessness in California: Patient Demographics By Facility

From 2019-2020, persons experiencing homelessness (PEH) accounted for 3.0 percent of hospital encounters in California hospitals.

The visualizations show the percent of encounters (IP hospitalizations or ED visits) for “Homeless” patients and the percent of encounters for “Non-Homeless” patients, which enables the user to identify disparities between the two groups. The statewide percentages are provided in the hover over function (Tool Tip) for each of the bar charts to compare custom selections to the related statewide percentages.

From 2019-2020, there were 896,185 encounters for persons experiencing homelessness: 237,541 inpatient (IP) hospitalizations and 658,644 emergency department (ED) visits. For Non-Homeless patients, there were 29,246,708 encounters: 7,034,191 IP hospitalizations and 22,212,517 ED visits. 

Age Group

The visualization below displays four age groups for patient encounters. Within each age group, the percent of encounters for both “Homeless” patients and “Non-Homeless” patients is displayed.

  • For both encounter settings combined, the “19 to 39” combined with the “40 to 59” age group account for 81.2 percent of encounters for PEH versus 52.7 percent for Non-Homeless patients.
  • For Non-Homeless IP hospitalizations, the “60+” age group (41.2 percent) is the highest; however, for Non-Homeless ED visits, the “19 to 39” age group (32.5 percent) is greatest and the “60+” group ranks third at 22.6 percent.
