In this interactive lesson, students will learn about New Deal policies that shaped residential housing patterns, often resulting in segregated communities. Using photographs, maps, videos, and graphs, students will analyze how residential security maps created by the Home Owners’ Loan Corporation, developers’ segregation walls, public housing projects, as well as the interstate highway system were connected to government policies and lay at the root of residential segregation. At the end of the lesson, students will consider how past policies and practices have affected the quality and rate of homeownership among different racial and ethnic groups. Students will then answer the lesson’s essential question: How have government policies and practices contributed to residential segregation?
