What is the term used to describe the process of renewing the outer areas of towns and cities?

Urban renewal refers to the process of redeveloping and revitalizing outer areas of towns and cities. This process typically involves improving infrastructure, enhancing public spaces, and upgrading housing, thereby aiming to revitalize areas that may be declining or in need of renovation. The focus is not just on physical structures but also on improving the quality of life for residents and addressing social issues associated with urban decay, all while fostering economic activity.

Gentrification, while related, is often characterized by the influx of wealthier individuals into previously lower-income neighborhoods, which can lead to the displacement of long-time residents. Rehabilitation typically refers to the restoration or repair of existing buildings rather than a broader area-wide effort. Centrification is not a widely recognized term in the context of urban development and doesn't accurately describe the renewal process. Thus, urban renewal is the most accurate term for describing efforts aimed at improving the overall conditions of town and city peripheries.
