Gentrification refers to a transformation in the composition of land users whereby incoming users possess a higher socio-economic status than those they replace, accompanied by reinvestment in the built environment and the physical transformation of urban space. Displacement is an essential part of this process. Gentrification has become one of the central analytical concepts in urban studies. Gentrification has become one of the central analytical concepts in urban studies enabling the analysis of socio-spatial restructuring processes in cities and has been applied to a broad range of geographical settings and historical conditions. Originally coined in the context of post-war London, the concept
has since traveled widely and has been applied to a broad range of geographical settings and historical conditions. This entry provides a comprehensive overview of the evolution of the concept, its principal theoretical interpretations, and its empirical applications. It reviews the major strands of explanation—demand-side, supply-side, and institutionalist approaches—and situates them within broader debates in urban theory. Particular attention is devoted to the relationship between gentrification and displacement, including both classical conceptualizations and recent efforts to capture its more diffuse and subjective dimensions. The entry concludes by arguing that while gentrification remains a key
concept for analyzing urban change, it must be continuously reworked in light of emerging dynamics such as financialization, digitalization, and trans-local housing practices. It calls for more systematic and genuinely comparative research in order to better understand the evolving geographies of gentrification.
By the late 1970s and early 1980s, gentrification research had developed into a major field of inquiry, but it was also marked by intense theoretical disagreements. Central to these debates was the question of causality: whether gentrification should be explained primarily through shifts in demand—such as changing lifestyles, demographic structures, and preferences—or through transformations in the dynamics of capital investment and property markets. These competing perspectives came to be known as demand-side and supply-side approaches, respectively, and structured much of the subsequent literature [2]. It was also in this context that the first feminist interventions into the debate were made
(see Section 3.1).
During the 1980s and 1990s, the concept was re-introduced into Western European debates. However, differences in welfare regimes, housing systems, and planning traditions led to renewed scrutiny regarding its applicability. Researchers increasingly emphasized the importance of contextual variation, arguing that gentrification processes are shaped by specific institutional and historical conditions. At the same time, the concept was extended to encompass a growing variety of phenomena, including commercial gentrification [3], new-build gentrification [4,5], tourist gentrification [6], rural gentrification [7,8], studentification [9], super-gentrification [10,11], green gentrification [12–14], ecological gentrification [15] and low-carbon [16] gentrification.
While this diversification expanded the empirical scope of the concept, it also generated concerns regarding its analytical coherence. A number of scholars argued that the term risked becoming overly inclusive and conceptually diluted [17–22]. These critiques were further reinforced by the rise of postcolonial urban theory, which questioned the universal applicability of concepts derived from Euro-American experiences. From this
perspective, gentrification was seen as reflecting a historically specific trajectory that could not be uncritically generalized to other contexts [23–25].
