Urbanization & its problems
Examines India's urbanization—its drivers, census definitions, and afflictions like slums, sanitation deficits and urban governance failures—for UPSC GS-1.
What Urbanization Means in the Indian Context
Urbanization is the demographic shift of population from rural to urban settlements and the consequent transformation of economy, society and spatial form. India remains predominantly rural, but the pace of urban transition has quickened. Census 2011 recorded India's urban population at 377.1 million, or 31.16% of the total—up from 27.81% in 2001. For the first time since Independence, the decade 2001–2011 added more people to urban areas (91 million) than to rural areas (90.6 million).
The Census of India defines an urban unit through two routes. A Statutory Town has a municipality, corporation, cantonment board or notified town area committee. A Census Town satisfies three demographic criteria simultaneously: a minimum population of 5,000; at least 75% of the male main workforce engaged in non-agricultural pursuits; and a density of at least 400 persons per square kilometre. The 2011 Census saw a striking surge in Census Towns—from 1,362 in 2001 to 3,894—evidence of 'in-situ' urbanization where villages acquire urban characteristics without administrative reclassification.
Drivers and Pattern of Urban Growth
Four processes drive Indian urbanization. Natural increase within existing urban areas remains the largest single contributor. Rural-to-urban migration, propelled by agrarian distress (push) and industrial-service employment (pull), accelerated after the 1991 liberalization. Reclassification of rural settlements into Census Towns adds to the count. Annexation expands municipal boundaries to absorb peripheral villages.
Indian urbanization is top-heavy and lopsided. Class I cities (population above 100,000) and especially the metropolitan cities house a disproportionate share of urbanites; the 53 million-plus cities of 2011 (up from 35 in 2001) concentrated 42.6% of the urban population. This is over-urbanization in the megacities coexisting with under-urbanization across the small and medium towns that lack the economic base to retain population. The phenomenon of degenerated peripheralization—poor populations pushed to ill-serviced city fringes—accompanies this skew.
The economic logic is decisive. Urban India generates roughly 60% of GDP from less than a third of the population, and the McKinsey Global Institute (2010) projected nearly 70% of net new employment to 2030 would be urban. Urbanization is therefore not a problem to be reversed but a process to be planned. The constitutional architecture for this rests on the 74th Constitutional Amendment Act, 1992, which created Urban Local Bodies, inserted the Twelfth Schedule listing 18 functions (urban planning, water supply, slum improvement, fire services), and mandated District Planning Committees (Article 243ZD) and Metropolitan Planning Committees (Article 243ZE). Its weak implementation—incomplete devolution of funds, functions and functionaries—is central to India's urban governance deficit.
