How does gentrification change neighborhoods?
Gentrification is the process by which investment and higher-income demand change property values and the social structure of a lower-income neighborhood.
Formation process and geographic mechanism
New transport, public investment, central location or cultural appeal may attract private capital. Buildings improve, businesses open and the tax base can grow. At the same time rising rents, taxes and service prices can pressure existing tenants and small firms. Displacement includes not only eviction but loss of social networks and cultural spaces.
Spatial outcomes, measurement and management
Not every neighborhood change is gentrification; income, rent, ownership, population and displacement data must be tracked through time. Tools include social housing, tenant protection, community land trusts and local-business support. The goal is not necessarily to stop investment but to share benefits with existing residents.
