Homeless students
share housing with other persons due to loss of housing or economic hardship, live in hotels or motels, trailer parks, or campgrounds due to lack of alternative arrangements, those awaiting foster care placement, living in substandard housing, and children of migrant workers (CRS, 2018)

good list of characteristics - some of these are in the housing unit and person record inventory. Shared housing, trailer parks - could be identified in the data. Foster care might be something to summarize - the census bureau has counts of people in foster care.

I will see if I can flag shared housing. The person record inventory has household structure - could be based on number of adults to children. I would assume that shared housing would have multiple adults (3-4+) and multiple children (3+)

According to the National School Boards Association, during the 2018-2019 school year, 77% of homeless students lived in shared housing, 12% lived in shelters, transitional housing, or were awaiting foster care, 7% lived in hotels or motels, and 4% were unsheltered (Cai, 2021).
