The sociology of development studies large-scale social transformation and the vocabulary in which it is described. It examines how societies move from agrarian to industrial and service economies, how states and international agencies attempt to direct that movement, who gains and who is displaced by it, and how the word development itself came to organise the post-1945 world into the advanced and the backward. It is thus a field with a double object: the processes of change, and the discourse that names some societies as lacking.
Its questions are contentious. Is underdevelopment an early stage that every society passes through, or a condition actively produced by the same history that made others rich? Are the obstacles internal — values, institutions, tradition — or external, lodged in trade, debt and empire? Should development be measured by output, or by what people are actually able to do and be? And can a project conceived and financed from outside ever be the self-transformation of a society?
Modernisation theory
The dominant post-war account treated development as a transition every society undergoes along a broadly similar path. W. W. Rostow's The Stages of Economic Growth set out five stages from traditional society through the preconditions for take-off, the take-off itself, the drive to maturity and the age of high mass consumption, with a rise in the investment rate as the mechanism. Parsons's pattern variables gave the sociological version: modernity means moving from ascription to achievement, particularism to universalism, diffuseness to specificity and affectivity to affective neutrality. Cultural variants located the missing ingredient in values — David McClelland's need for achievement, Everett Hagen's status withdrawal — while diffusion accounts held that capital, technology and attitudes would spread from advanced centres outward.
The theory carried heavy assumptions: that tradition and modernity are exclusive opposites, that the Western trajectory is the general case, that change proceeds by imitation, and that internal deficiencies explain poverty. Each was subsequently attacked. Empirically, tradition proved compatible with growth and even its vehicle; caste associations, kin networks and religious identities turned out to organise modern politics and enterprise rather than dissolving before them.
Dependency, world-systems and post-development
Latin American scholarship reversed the causal arrow. Raúl Prebisch's argument about declining terms of trade for primary exporters, radicalised by Andre Gunder Frank into the development of underdevelopment, held that metropolitan centres extract surplus from satellites through a chain reaching into the countryside, so that the periphery's poverty is the product, not the absence, of its integration into world capitalism. Fernando Henrique Cardoso and Enzo Faletto softened this into associated dependent development, allowing for industrialisation that remains structurally subordinate. Immanuel Wallerstein recast the whole in world-systems terms: a single capitalist world-economy since the long sixteenth century, differentiated into core, periphery and semi-periphery by an axial division of labour, with mobility between zones possible but the hierarchy itself permanent. Critics objected that the approach subordinates class relations to trade position and leaves little room for national politics.
A third position denies the terms of the argument. Arturo Escobar's Encountering Development treats development as a discourse created after 1945, which constituted two-thirds of humanity as underdeveloped, converted poverty into a technical problem for expert intervention, and thereby extended a form of power. Post-development writers accordingly look to local knowledge, subsistence economies and social movements rather than to better development plans. The charge against them is romanticism about poverty and an inability to say what should be done.
Capabilities, participation and the human turn
Amartya Sen's work moved the criterion of development from income to capability — the substantive freedoms people have to lead lives they value. Growth, resources and utility are means and imperfect ones, since converting income into functioning depends on health, education, gender and social arrangement. Martha Nussbaum developed the approach into a list of central human capabilities for use in political principle. The capability approach supplied the intellectual basis of the Human Development Index and of the argument that literacy, longevity and freedom from hunger are constitutive of development rather than by-products of growth.
Running alongside is the participatory turn — the claim that development must be designed with those it affects, through participatory appraisal, decentralisation and community organisation. Its critics note that participation can become a ritual that legitimises decisions already taken, and the NGO-isation debate asks whether the professionalisation of voluntary action converts political movements into donor-funded service delivery, dependent on external finance and answerable upwards rather than to constituents.
The Indian field
India offers an unusually documented case. The Nehruvian settlement combined planning, a mixed economy and heavy industry under public ownership, with the Mahalanobis model shaping the Second Plan and community development seeking rural transformation from below. A. R. Desai criticised the official conception for ignoring class structure and asking whether planning served the propertied. Land reform abolished intermediaries but largely failed on ceilings and tenancy; the green revolution secured food supply while widening regional and class disparities; and dams, mines and industrial projects produced development-induced displacement on a scale that made resettlement a sociological field of its own, with adivasi and Dalit communities disproportionately affected.
The 1991 liberalisation shifted the state from producer to regulator, raised growth sharply and reduced income poverty, while critics pointed to jobless growth, agrarian distress, the informality of most employment and widening regional and social inequality. The subsequent rights-based phase — employment guarantee, right to information, right to education, food security — reframed entitlements as justiciable claims rather than discretionary schemes, and remains the most distinctive Indian contribution to development practice.
Current directions
Current work concentrates on inequality rather than poverty alone, on the measurement of well-being through multidimensional indices, on climate and the sustainability constraint on growth, on digital infrastructures and welfare delivery, on migration and remittances as development from below, and on the rise of southern donors and the politics of the Sustainable Development Goals.
For the UPSC answer
Set modernisation theory out properly — Rostow's stages, Parsons's pattern variables, the values and diffusion assumptions — before criticising it, since the marks lie in the contrast. Move to Frank and Wallerstein for the external explanation, then to Escobar to show that a third position rejects the question itself, and to Sen to shift the criterion from income to freedom. On India, run the sequence from planning and the mixed economy through land reform and the green revolution to displacement, liberalisation and the rights-based turn, and close by naming inequality and sustainability as the live questions.
