Gentrification has become a critical issue in many cities around the world, as neighborhoods experience rapid change in a relatively short period of time. Although it is a controversial subject, it is often seen as a natural part of urban development. The term gentrification is largely credited to Ruth Glass, a British sociologist, who defined it in 1964 as, “[the] process by which the middle-class move into lower-class neighbourhoods, changing the working-class values, ideas and also the feel of such places”.

Gentrification is characterised by an influx of in-migrants to historically disinvested inner-city neighborhoods; these new residents are typically more affluent than the local community and have a distinct set of preferences, tastes and cultural experiences, resulting in changes to the built form and urban landscape. Gentrification is usually accompanied by rising property values and rents, as well as higher incomes and spending. Over time, many of the original residents of the gentrified neighborhood may find it difficult to afford living in the area and are typically displaced, often leading to increased poverty and racial/ethnic segregation in other parts of the city.

The process of gentrification can bring a multitude of benefits. Examples of such include revitalizing and updating historical structures, creating new housing, fostering cultural diversity and creating a larger tax base that can provide the resources to adequately serve and improve the community. Additionally, gentrification can lead to an improvement in the public and commercial infrastructure and a decrease in crime in former areas of urban blight. All of these benefits can result in an overall improved neighborhood and even citywide quality of life.

However, gentrification also has numerous downsides. The displacement of the low-income and minority residents that often come with gentrification can dramatically increase housing prices and rents, leading to further concentrations of poverty and social unrest in other parts of the city. Additionally, the displacement of the (often working-class) cultural aspects that were once prevalent in the neighborhood can be lost, forever changing the character and feel of the area. Furthermore, gentrification can lead to an increase in public and commercial services that are too expensive for some, limiting their access to the area.

Given the complexity of gentrification and its often far-reaching consequences, it is essential that cities around the world look for ways to manage the process. Such practices include, but are not limited to, providing low-income housing and rent control, encouraging the development of mixed-income projects, protecting small businesses and creating more infrastructure for all. It is only by taking deliberate action that cities can ensure equitable and just neighborhoods for all.
