How do housing markets contribute to urban segregation by income or race?

• A. Through zoning that only sets building heights not affecting access.
• B. Segregation is solely due to personal preferences.
• C. Markets always promote integration.
• D. Housing costs, credit constraints, and zoning limit access to higher-opportunity neighborhoods; segregation arises from price signals, waiting lists, and school funding disparities that cluster by income or race.

Answer: (D)

Housing markets sort where people can live through housing costs, access to credit, and land-use rules. When prices are high in higher‑opportunity neighborhoods, households with lower incomes or weaker credit can’t move there, so they remain in less advantaged areas. Zoning that limits new housing supply keeps these prices elevated in desirable places, amplifying the separation. As rents and house prices rise in the sought-after zones, price signals attract wealthier households while others are priced out, creating segregation by income and, because these patterns align with race in many places, by race as well. The effect is reinforced by how local property taxes fund schools; better-funded schools in wealthier, high‑cost areas attract families and sustain the appeal of those neighborhoods, further concentrating opportunity. Waiting lists and limits on affordable units channel lower‑income families into specific areas, adding to the pattern. So, segregation arises from the interaction of housing costs, credit constraints, and zoning, along with the way price signals shape where people can live and how schools are funded, rather than from personal preferences alone.
