सारांश	Shrinking cities analysis is the study of cities and neighbourhoods that are losing population and economic activity, tracing the demographic decline, job loss, housing vacancy, and infrastructural over-capacity that follow, and the 'right-sizing' planning responses they provoke. It treats shrinkage not as the temporary failure of a growth path but as a distinct, often persistent urban trajectory requiring its own descriptive tools. The conceptual synthesis by Haase and colleagues in 2014 frames urban shrinkage as a multidimensional process linking population loss, economic restructuring, and changes in the built environment.	Gentrification analysis is the set of methods used to detect, measure, and map the process by which a previously disinvested, lower-income neighbourhood is upgraded through an influx of capital and higher-status residents, often displacing the existing population. It typically combines repeated small-area census data on income, education, tenure, and rents with housing-market indicators to compute change indices that flag where socioeconomic status is rising fastest. Grounded in Neil Smith's 1979 rent-gap theory, the analysis frames gentrification as the reinvestment of capital in places where the gap between actual and potential land rent has grown large enough to be profitable.
