This chapter discusses new policies to counter those that have been destructive to communities, led to the incessant displacement of communities, and effectively created the social context for the emergence of health disparities. The chapter uses interviews and observations collected as part of a study of urban renewal to suggest that these seemingly discrete policies have interacted to create a set of disadvantages that contribute to the spread of AIDS and as well as other health and social problems. It proposes that incessant displacement is at the root of America’s health disparities. The chapter analyzes interviews for comments specific to the policies of segregation, redlining, urban renewal, planned shrinkage/catastrophic disinvestment, gentrification, HOPE VI, and mass incarceration. In addition, the chapter examines the movement of populations over time in the Newark, NJ area using methods from population, community, and ecosystem ecology and quantitative geography.
