How has homeless changed in the United States?

How is homelessness changing in U.S. cities? As median rents have risen across the United States, so too has the number of people experiencing homelessness. Some cities have prioritized sheltering their homeless population while others have not.

Student write linear equations approximating the annual rate of change in the sheltered, unsheltered, and total homeless populations, based on data from two points in time. They use these equations to predict the size of these populations in the future. Students brainstorm and discuss possible interventions by various parties, including themselves.
