Urban sociology asks what difference the city makes. Cities concentrate people of unlike origins in small space, sustain a division of labour of extraordinary depth, and organise strangers into workable order without the face-to-face knowledge that governs a village. The field studies the consequences: for personality and mental life, for the forms of association that replace kinship, for the spatial sorting of classes and communities, and for the politics of who gets housing, water and the right to remain.
Two framings recur. One treats the city as a way of life — density, heterogeneity and size producing characteristic social psychology and institutions. The other treats the city as produced space — the outcome of investment, speculation, planning and struggle, so that segregation and slums are effects of capital and policy rather than of urbanism as such. Much of the discipline's development is the movement from the first framing to the second, and the partial return of the first in studies of urban sociality.
Classical foundations
Georg Simmel's essay on the metropolis argued that the intensification of nervous stimulation forces a defensive blasé attitude and a shift from the heart to the head: the metropolitan personality is calculating, reserved and punctual because the money economy and the clock demand it. Yet the same impersonality liberates. Freed from the surveillance of the small town, the individual acquires room for eccentricity and self-development. Simmel thus gave the field both its diagnosis of urban anomie and its defence of urban freedom.
Max Weber's The City proceeded comparatively and historically. A full urban community, for Weber, required a fortification, a market, an autonomous court and law, an associational character, and at least partial political autonomy — features he found in the medieval Occidental city with its sworn confraternities of burghers and its status as a corporate body. Asian cities, he argued, were administrative and princely centres embedded in kin and caste orders and lacked such autonomy. The argument has been much criticised as Eurocentric, but it established the city as a political and legal form, not merely a settlement of a certain size.
The Chicago School made urban sociology an empirical enterprise. Robert Park proposed human ecology, reading the city as a mosaic of natural areas produced by competition, invasion and succession, and urged students out onto the streets. Ernest Burgess's concentric zone model described growth outward from the central business district through a zone in transition, workingmen's homes, better residences and the commuter belt, with social disorganisation concentrated in the inner ring; later ecologists offered Homer Hoyt's sector model and Harris and Ullman's multiple nuclei. Louis Wirth's “Urbanism as a Way of Life” distilled the theory: size, density and heterogeneity yield segmental and secondary relationships, superficiality and anonymity, the substitution of formal control for custom, and a susceptibility to personal disorganisation.
Community lost, saved, liberated
Wirth's picture invited rebuttal. Herbert Gans's The Urban Villagers, a study of Italian Americans in Boston's West End, found dense kinship, peer-group sociability and neighbourhood attachment in the middle of a supposedly disorganised slum — an urban village, later cleared by renewal. Gans proposed that class and life-cycle stage, not urban location, explain ways of life; Michael Young and Peter Willmott found similar solidarities in Bethnal Green. Barry Wellman's “community liberated” argument recast the debate: urbanites keep intimate ties, but ties dispersed across the city and chosen rather than inherited. The corrective did not vindicate the village; it separated community from locality.
The political economy turn
From the 1970s, a new urban sociology rejected ecology's naturalism. Manuel Castells, in The Urban Question, denied that the city was a theoretical object at all and redefined the urban as the spatial unit of collective consumption — housing, transport, schooling — organised by the state and therefore a site of urban social movements. David Harvey analysed the built environment as a secondary circuit for surplus capital, generating rounds of creative destruction and rent extraction. Henri Lefebvre's right to the city — a claim to participate in and appropriate urban space, not merely to inhabit it — became the vocabulary of movements against eviction and privatisation. Later work on global cities (Saskia Sassen), gentrification and neoliberal urban governance extended the line, while Castells himself moved to the informational city and the space of flows.
The Indian field
Indian urbanisation has never fitted the Western sequence. The over-urbanisation thesis, associated with Kingsley Davis and Bert Hoselitz and criticised by N. V. Sovani, held that Indian cities grew faster than industrial employment could absorb, producing labour surplus and swollen service sectors — a case of urbanisation without industrialisation, driven by rural push as much as urban pull. Indian scholarship, gathered by M. S. A. Rao and Ashish Bose, added a distinctive agenda.
Four themes dominate. Migration is largely circular and male-dominated, with households split across village and city and remittances tying the two; the urban worker is often a villager on rotation rather than a permanent citizen. Slums and informal settlements raise questions of tenure, demolition, resettlement and the politics of encroachment; the informal sector houses most urban work, so the study of the slum is inseparable from the study of the informal sector. Caste and community persist in the city — in occupational niches, marriage circles, residential clustering and communal riot geographies — refuting the assumption that anonymity dissolves ascription. Finally, governance and segregation: fragmented metropolitan authority across municipalities and parastatals, the rise of gated enclaves, private townships and resident welfare associations, and the smart-city and world-class-city discourse that has often meant beautification and eviction rather than services for the poor.
Current directions
Recent work studies peri-urban transformation and land conversion, urban ecology and flooding, platform-mediated delivery work, women's access to public space, and the comparative theory of cities of the global South against categories built from Chicago and Paris.
For the UPSC answer
Move through the classics in order — Simmel on the metropolitan personality, Weber on the city as a political and legal community, Park, Burgess and Wirth on urbanism as a way of life — then use Gans's urban villagers as the standing empirical rebuttal that class and life cycle, not density, make ways of life. Mark the political economy turn clearly with Castells on collective consumption, Harvey on the built environment and Lefebvre's right to the city. For India, deploy over-urbanisation with Sovani's caveat, and illustrate with circular migration, the informal sector, caste in the city, and the gated-enclave and smart-city contrast. A single sentence noting that Indian urbanisation is best read as demographic and political rather than simply industrial will lift the answer.
