India's urban transition and migration: the gap between city growth and municipal capacity

The structural picture, in numbers

India’s urban transition is real but, by the standard of comparable economies, still incomplete on paper. As per Census 2011 — the last completed count — about 377 million people, or 31.16% of the population, lived in urban areas, and it was the first decade in which India’s towns and cities added more people than its villages (MoHUA). Movement is larger than the urban share suggests: Census 2011 counted about 45.36 crore internal migrants (roughly 37% of the population) by place of last residence, though the great majority of those are women migrating for marriage and much of the movement is short-distance and rural-to-rural (PRS).

More recent measurement comes from the Periodic Labour Force Survey’s migration module for 2020-21, which put the overall migration rate at 28.9% — 10.7% among males and 47.9% among females. Among female migrants, marriage was the reason in about 86.8% of cases, while among male migrants employment or better employment was the single largest reason at 22.8%; the urban migration rate (34.9%) exceeded the rural rate (26.5%) (PIB). The gendered split is the reason headline migration figures understate the labour flows that actually strain cities: employment migration, disproportionately male and inter-state, is a minority of all migration but the part that builds and staffs urban economies.

The institutions and data systems

No single authority owns the urban-and-migration system; it is split across the statistical state and several ministries.

Who counts it. The decennial Census is run by the Office of the Registrar General and Census Commissioner under the Ministry of Home Affairs, and it defines what counts as “urban” — statutory towns (with a municipality) plus census towns (population above 5,000, density above 400 per sq km, and over three-quarters of the male workforce in non-farm work). The Ministry of Statistics compiles the PLFS and its migration module and is now fielding a dedicated National Migration Survey.

Who delivers. The Ministry of Housing and Urban Affairs sets urban policy and co-finances the big city programmes — AMRUT, the urban Pradhan Mantri Awas Yojana, the Metro Rail Policy and, until its closure in March 2025, the Smart Cities Mission — but does not run cities. Cities are governed by state governments and by the municipal bodies that the 74th Constitutional Amendment gave constitutional status in 1992, with a Twelfth Schedule of functions meant for devolution and State Finance Commissions meant to fund them.

Who governs the workers. Migrant labour is a subject of the Ministry of Labour. The Inter-State Migrant Workmen (Regulation of Employment and Conditions of Service) Act, 1979 was the dedicated migrant-labour statute for four decades before being repealed into the Occupational Safety, Health and Working Conditions Code, 2020 (Wikipedia). The e-Shram portal, launched in 2021, is the first national register of unorganised workers — including migrant, construction, gig and platform workers — and later crossed 30 crore registrations (e-Shram). One Nation One Ration Card, pushed nationally after 2020, made a migrant’s food-grain entitlement portable across states.

Two data refreshes now under way

Two things are changing the evidence base at once, both in the 2026-27 window.

The delayed Census is finally scheduled. The government’s intent to conduct the Census was notified in the Gazette on 16 June 2025, with a reference date of 1 March 2027 (1 October 2026 for snow-bound areas of Ladakh, Jammu & Kashmir, Himachal Pradesh and Uttarakhand). It is designed as India’s first digital census, run in two phases, and — following an April 2025 Cabinet decision — is to enumerate caste; the second, population-enumeration phase is intended to capture migration and fertility data (PIB). Separately, the National Statistical Office announced a dedicated National Migration Survey reported to run from July 2026 to June 2027 — the first standalone national migration survey since the NSS 64th round of 2007-08 (DD News). Between them they are the first serious attempt to refresh the picture since 2011.

The capacity gap, quantified

The theme’s organising fact is that cities have grown faster than the money and authority of the bodies meant to run them. In its Report on Municipal Finances (released 13 November 2024, covering 232 municipal corporations), the Reserve Bank found that municipal corporations’ revenue was about 0.6% of GDP in 2023-24 — roughly half from their own sources and the rest from transfers from higher tiers, and a fraction of central (9.2%) and state (14.6%) revenues (Business Standard). By a widely cited comparison drawn from the same body of RBI municipal-finance analysis, India’s municipal revenues have stagnated near 1% of GDP for more than a decade, against roughly 7% of GDP in Brazil and 6% in South Africa. This is the fiscal expression of a governance point: the 74th Amendment created city governments but left the devolution of funds, functions and staff to state discretion, so many municipal bodies plan and tax weakly even as their populations and informal settlements expand.

The live debates (attributed)

Is India under-urbanised, or under-counted? One camp reads the 31% urban share as evidence that India remains structurally rural. Another points to the 2011 surge in census towns — from 1,362 in 2001 to 3,894 — settlements that are urban in economy but still governed as rural gram panchayats, and argues that India’s administrative definition of “urban” hides a larger, in-situ urban transition. Both readings use the same Census data and reach different conclusions about how urban India actually is; the question is definitional as much as empirical.

Did the labour codes strengthen or dilute migrant protection? The government’s position is that folding the 1979 Act into the OSH Code, 2020 modernised and widened coverage — extending the inter-state migrant category and adding portability of benefits. Critics, including legal-policy researchers and trade unions, argue the codes removed migrant-specific protections by treating inter-state migrants largely as contract workers, and that raising the applicability threshold leaves workers in small establishments outside the law’s reach (Vidhi). Some unions have publicly demanded the 1979 Act’s restoration. This brief attributes rather than adjudicates the dispute. (The four labour codes were brought into force in November 2025; see Labour.)

Were migrant workers governable at all in a crisis? The 2020 lockdown, which set off a mass reverse migration on foot, exposed that no arm of the state held a count of inter-state migrant workers; the government told Parliament it had no data on migrant-worker deaths during the exodus. The Supreme Court took suo motu cognisance and pressed for community kitchens, ration portability and a national worker register (PRS). e-Shram and the national rollout of One Nation One Ration Card are the direct institutional responses; whether registration translates into portable rights on the ground is contested and, until the 2026-27 surveys report, hard to measure.

Settled versus contested

Settled, on the record: the 2011 urban share (31.16%) and migrant count (~45.36 crore); the PLFS 2020-21 migration rate (28.9%) and its gender split; the Census 2027 schedule and its two-phase, digital, caste-enumerating design; the National Migration Survey window (July 2026-June 2027); the repeal of the 1979 Act into the OSH Code; and the RBI’s municipal-revenue figure of about 0.6% of GDP (2023-24). Contested, and attributed above: how urban India really is under a different definition; whether the labour codes advanced or eroded migrant protection; and whether the post-2020 registers deliver portable rights in practice. The single largest uncertainty running under all of it is that the country has planned and targeted welfare on 2011 population data for 16 years — a gap the 2027 Census is meant to close.

Who owns this topic (and why we are here)

Search results for “urbanisation in India”, “internal migration” and “migrant workers” are dominated by two kinds of page: civil-services exam mills (Drishti IAS, Vision IAS, Testbook, Vajiram & Ravi, BYJU’S) that flatten the subject into prelims factoids, and one-off news pieces pegged to a single event — a lockdown, a Census announcement, an RBI report — that are never reconciled into a standing view. Neither states the current, sourced position across the whole system: what the last real numbers are, which two data refreshes are now in the field, what the RBI actually found about city finances, and where the labour-law dispute stands. IndiaStand out-structures both by holding one institution-anchored brief that spans the urban, labour, statistics, home-affairs and central-bank desks at once, separates verified structure from live debate, attributes every claim, and updates as the Census, the migration survey and the courts move.
