Understanding neighborhood change: An approach to assessing displacement risk among NYC residents
Urban Studies and Planning
The SIAP research team has sought to develop methods to assess the complexity of rapid neighborhood change in New York and other U.S. cities. Reinvestment Fund developed an approach to identify locations in New York City where the housing market has changed in a way that residents who have been in a community for several years cannot likely be replaced by people of similar economic means. This paper discusses their method—called Displacement Risk Ratio (DRR)—for identifying areas at risk of displacement (or the inability to replace a resident population over time) based on the gap between housing costs and household income. The paper identifies six patterns in neighborhoods with significant DRR Sales increases as a preliminary typology of change: 1) transitioned from majority black or Hispanic to racially/ethnically diverse; 2) remained predominantly black or Hispanic; 3) remained predominantly white; 4) Asian immigrant neighborhoods; 5) remained diverse; and 6) high residential development areas. The conclusion reviews the potential for use of the DRR method to assess neighborhood change in New York City.
