Rapid Urbanization

Overview

This paper investigates the extent and spatial incidence of neighborhood socio-economic changes, such as gentrification, upgrading, and decline, across the 70 largest U.S. metropolitan areas between 1990 and 2010. The study utilizes the 3-D Double Decimal Difference method to identify neighborhoods that experienced substantial changes in median household income, revealing that neighborhood decline was more prevalent than upgrading during this period. The research provides insights into the factors driving these changes and their implications for urban planners and policymakers.

Key Message

Neighborhood socio-economic change is a complex and multifaceted process influenced by both metropolitan and local factors. The findings indicate that while upgrading and gentrification occurred, decline was the dominant trend in many metropolitan areas. Planners and policymakers should focus on mitigating decline by promoting stable and diverse neighborhoods through targeted investments and inclusive policies. Strategies to redistribute the benefits of upgrading and protect long-term residents from displacement are crucial for fostering sustainable and equitable urban development. The study underscores the importance of understanding local contexts and dynamics to effectively address the challenges and opportunities presented by neighborhood change.
