Note: This table is based on the full follow-up interview sample (n = 150).

H = homelessness, which includes respondents who responded “yes” to the questions explicitly asking about any youth homelessness, including those who reported both homelessness and couch surfing; C-o = couch surfing only, which includes respondents who responded “yes” to youth couch surfing and “no” to youth homelessness. Safe/normative/stably housed experiences that were interpreted as couch surfing included situations such as staying with friends or relatives recreationally or traveling for recreation or work while having access to a safe and stable living arrangement.
