Key points
- Ruth Glass coined gentrification in 1964 watching middle-class people renovate Victorian houses in Islington and displace residents.
- The concept outgrew its definition: from London terraces to new-build, tourist and global gentrification.
- Glass gave a framework for analysing how urban change reflects and reproduces social inequality.
The word gentrification was coined by Ruth Glass (1912–1990), a British sociologist of German origin, in the introduction to London: Aspects of Change (1964). With it she described a process she was watching in Islington and other working-class districts of London: middle-class people moving into and renovating Victorian houses, pushing property prices up and eventually displacing the original residents. Her analysis connected the physical transformation of the city directly to class divisions, and that connection is the basis of every study of the subject since.
A concept that outgrew its definition
The concept has expanded enormously since its formulation, but its essence still holds. Glass did not only point to the change of owners and the displacement: she saw in them the reflection of wider social and economic tensions in the modern city. Gentrification was not an isolated phenomenon in a few London neighbourhoods but part of a change in urban structures, driven by capital and by planning decisions that prioritised the interests of the emerging middle classes over those of the working classes.
From London to the world
With globalisation the concept has served to describe similar processes in cities around the world, from New York to Paris and from Mumbai to Mexico City. Glass's observation has been key to understanding how working-class neighbourhoods turn into areas of high property value, and it has opened debates on residents' rights and urban justice. Today gentrification is a central topic of urban studies, with a vast literature on its economic, social, cultural and political dimensions, from Neil Smith to Loretta Lees.
A changed urban landscape
Glass also noted that gentrification does not only affect individuals: it transforms the urban landscape. Rising housing prices, the privatisation of public space and the arrival of residents with different consumption habits change the neighbourhood's demography and also its culture and identity. That creates tensions between newcomers and long-standing residents, who watch their community transform without any capacity to influence the process: the bakery becomes a café, the market becomes a gourmet market.
What governments should do
The social impact of gentrification has produced an intense debate about the responsibility of governments to mitigate its effects. Some argue that it brings benefits — the revitalisation of run-down areas, better services — but it is documented that those benefits rarely reach the most vulnerable populations, who are the ones who leave. Glass's work is fundamental to understanding urbanism as a terrain of social struggle, where class and power dynamics are expressed in who occupies and uses space.
Ruth Glass did not only name gentrification: she gave a framework for analysing how urban change reflects and reproduces social inequality. Sixty years on, when cities around the world face the same problems of inequality, access to housing and the transformation of space, her short introduction of 1964 remains the obligatory starting point.
