Regional Disparities in Economic Development

• Regional disparities in economic development are a common feature across the world. The term regional disparity is used alongside regional imbalance, regional dualism and growth differentiation.
• It refers to differences in economic development and uneven economic achievement between geographical regions.
  • The coexistence of relatively developed and economically depressed States, and of such regions within each State, is known as regional imbalance, the wider concept treated under regional imbalances and balanced growth.
• Many countries show large gaps in economic performance and living standards, reflected in income, education and health.
• In India, disparities go back to the colonial period, and have been a main argument for planning since Independence.

Meaning and Significance

Why Disparities Matter

• Equity: they add to inequality within a country and are linked to inequality of opportunity, as measured by intergenerational mobility.
• Efficiency: limited opportunities for people stuck in the wrong place leave potential unused and hold back overall growth. Disparities between regions may slow the entire national economy.
• Social cohesion: gaps, including those between urban and rural areas, can feed social tensions, populism and resentment of urban elites.
  • In extreme cases they threaten national cohesion and lead to conflict, especially where they reinforce ethnic, racial, linguistic or religious divisions.
• Policy: development tends to concentrate in a few main territories. Others miss out because of market imperfections, geographical constraints, poor policy, weak law and order and other social, political and economic factors.
  • Measuring disparities is therefore a precondition for sound policy against what hinders growth.
• For geographers, the identification and analysis of regional disparities is the first step in studying regional development. The next steps are the spatial diffusion of development, its spatial consequences, and spatial models such as growth poles and core–periphery, which are set out in the theories of regional imbalance.

A World Problem

• Even the United States, the world’s largest economy, has imbalanced regional development. So do Italy and France, and Russia and China, whatever their economic systems.
  • Italy: the industrial north against the Mezzogiorno.
  • China: the eastern coast against the western interior.
• Regions grow at very unequal rates, which produces inter-regional and intra-regional disparities and, with them, socio-economic problems.

Regional Disparities in India

Evolution

• Colonial period: the British rulers and industrialists developed mainly those regions that suited prosperous manufacturing and trade and served their interests.
  • They concentrated on Calcutta (Kolkata), Bombay (Mumbai) and Madras (Chennai) rather than other cities.
  • Uneven investment in industry and in economic overheads (transport, communication, irrigation, power) laid the base of later disparities.
• Planning era: disparities across regions and among social groups were a major reason for adopting planning.
  • The Third Plan (1961–66) took up balanced regional development explicitly.
  • In the first three decades, the government stressed heavy industry in backward regions: the steel plants at Bhilai, Rourkela and Durgapur are the standard cases. The problem persisted, and later reviews held that plans had failed to reach the target of balanced regional development.
• Since the 1980s: faster growth appears to have aggravated disparities.
• Since 1991: stabilisation and deregulation seem to have widened them further, because the gains of growth were not shared equally among States.
  • Indian and foreign investors favoured regions that were already advanced industrially.
• Resources do not decide the outcome. Development depends on natural and human resources, yet many resource-endowed regions, such as Odisha (Orissa), Bihar and Jharkhand, have remained behind. Political and social factors matter as well.

Present Pattern

• The table sets out the main measures, each with its source and date.

• The income gap is widening. Across the 20 major States, the ratio of the highest to the lowest per capita NSDP rose from 4.9 in 2011–12 to 5.6 in 2023–24, with Telangana’s figure now 5.6 times Bihar’s.
• Social gaps are narrowing faster than income gaps. India’s multidimensional poverty headcount fell from 24.85% (2015–16) to 14.96% (2019–21).
• Rural and urban: average monthly per capita consumption in 2023–24 was ₹4,122 in rural and ₹6,996 in urban India. The urban lead narrowed from 84% to 70% of rural spending over 2011–12 to 2023–24.
• The digital divide is a newer layer of disparity: subscriptions counted per 100 people are about 2.6 times as high in urban as in rural India. These count connections, not unique users.
• Hill and plain: gaps between peripheral hill areas and the plains have fed separatist sentiment and insurgency in parts of the north-east, where development of Scheduled Tribe areas is a particular need.

Need for Balanced Regional Development

• Democracy: in a democratic polity, growth and prosperity must show regional balance, so a government working towards it is to be expected.
• Competitiveness: India has 28 States and 8 Union Territories (29 States in 2014–19), with different productive potential and suited to different industries. Realising that potential is the key to national competitiveness.
• Security and migration: disparity brings violent conflict and unplanned migration.
  • Insurgency in the north-east and Left Wing Extremism in central and eastern States are the usual examples.
  • Home Ministry counts of districts affected by Left Wing Extremism fell from 38 (April 2025) to 11 (October 2025), and the Ministry’s revised classification after the 31 March 2026 deadline classes no district as affected.
• National targets: sustaining growth and meeting development targets will be difficult unless India grows as an integrated whole of regional competencies.

Causes of Regional Disparity

• Historical factors:
  • The British developed only regions with rich potential for manufacturing and trade: port cities such as Bombay, and strategically important Calcutta and Madras, got the first start.
  • The absence of proper land reform and industrial policy kept growth below a satisfactory level.
• Geographical factors:
  • Flood-prone tracts, hills, rivers and dense forests raise the cost of administration and of projects, and make it harder to mobilise resources.
  • Himachal Pradesh, Jammu and Kashmir, Uttarakhand and the north-eastern States lagged because of inaccessibility and other inherent difficulties.
• Location-specific advantages:
  • Irrigation, raw materials, markets and ports draw development projects to certain regions. Oil refineries, for example, are mostly sited close to the sea.
• Early-mover advantage:
  • New private investment concentrates where basic infrastructure already exists.
  • Term-lending institutions and commercial banks also favour the more developed States.
• Failure of the planning mechanism:
  • Neglect of local needs, a one-size-fits-all approach, inadequate resources, poor implementation and little planning capacity at State level limited what the Planning Commission could achieve on balance.
  • Land redistribution moved slowly, which also held back farm growth.
• Restricted success of the Green Revolution:
  • It improved agriculture through high-yielding seeds, assured irrigation and technical know-how.
  • The gains went mainly to Punjab, Haryana and western Uttar Pradesh, which had irrigation, a wheat-growing tradition and policy support from their State governments. Parts of Andhra Pradesh and Tamil Nadu gained in rice.
  • Eastern India and the arid, rainfed, hilly and coastal zones gained little. Among States in 1975–78, the highest wheat yield was about 3.7 times the lowest, and for paddy about 3.2 times.
• Law and order:
  • Extremist violence and law and order problems have deterred investment in backward regions and driven capital out of them.
• Liberalisation:
  • After the New Industrial Policy (1991), investment favoured industrially advanced States such as Maharashtra and Gujarat, while Bihar, Uttar Pradesh and the north-eastern States gained least.
• The geographical and socio-economic bases of these causes are compared in full under regional imbalances.

Intra-Regional Disparity

• Large gaps exist within States, such as Vidarbha in Maharashtra and Saurashtra in Gujarat.
  • Article 371(2) provides for development boards for Vidarbha, Marathwada and the rest of Maharashtra, and for Saurashtra, Kutch and the rest of Gujarat.
• State formation: the demand for some States drew on perceived neglect of backward regions, along with language and identity.
  • Andhra State (1953), later Andhra Pradesh (1956), and Gujarat (1 May 1960).
  • Punjab and Haryana (1966), with Himachal Pradesh enlarged in 1966 and made a State in 1971.
  • Telangana (2 June 2014) is the most recent such case.
• Causes differ by State:
  • Scarcity of water is the major cause of backwardness in Vidarbha, Marathwada and northern Karnataka.
  • Tribal-majority tracts of Gujarat, Madhya Pradesh, Bihar (now largely Jharkhand) and Odisha have been remote and neglected in public investment, with distinct ways of life that uniform plans have often overlooked.

Government Interventions

Resource Transfers

• Transfers from the Centre to backward States ran through two channels:
  • The Planning Commission, mainly as plan transfers, until it gave way to NITI Aayog on 1 January 2015.
  • The Finance Commission, as non-plan transfers.
• Special Category status was introduced in 1969 to give certain hill and border States a greater share of central grants. It carried through to the 13th Finance Commission. The 14th made no such distinction in its tax devolution.
  • The status still shapes central scheme funding: 90 : 10 against 60 : 40 for general States.
• Income distance measures how far a State’s per capita income lies below the richest, and is the main tool for closing per capita income gaps.

• The 16th Finance Commission, whose report was tabled on 1 February 2026, also gives population 17.5%, and demographic performance, area, forest cover and contribution to GDP 10% each.
  • The new contribution to GDP criterion rewards efficiency. Supporters see fairness to States that generate more revenue, and critics see a dilution of the equity aim.

Development Programmes

• General programmes in agriculture, irrigation and power, transport and communications and social services aim at basic facilities for all regions, along with the Community Development Programme and the Drought Prone Areas Programme.
• Areas that lag industrially have received river valley and multipurpose projects:
  • Sardar Sarovar on the Narmada (dedicated 2017) for the dry parts of Gujarat and Rajasthan, with power for Madhya Pradesh and Maharashtra as well.
  • The Ken-Betwa link for Bundelkhand, whose foundation stone was laid on 25 December 2024.
• Identifying backward areas became systematic in the 1960s:
  • A Committee on the Dispersal of Industries (1960) judged districts by poverty, crowding on the land, weak communications, joblessness and power use.
  • The Pande Working Group (1968–69) used per capita income, income from industry and mining, factory workers, electricity use, and road and rail length. It classed ten States as industrially backward, and later work identified 238 districts.
  • The Wanchoo Working Group recommended fiscal and financial incentives. These details are set out under backward area planning.
• Village and small industries:
  • They are spread across the country and receive Central and State assistance under various programmes.
  • Industrial estates, begun in 1955 with 12 sanctioned estates, now exist in all States, increasingly in smaller towns and rural areas.

Diffusion of Industry and Infrastructure

• Public sector location: the claims of relatively backward areas were kept in view wherever technical and economic criteria allowed.
• Roads in the north-east: the East–West Corridor, the Special Accelerated Road Development Programme for the North-East (SARDP-NE) and the Trans-Arunachal Highway improve connectivity.
• Railways in the north-east:
  • An older count listed 25 rail projects under way, 11 of them national projects.
  • A Rajya Sabha reply of July 2025 gave 12 approved projects of 777 km, costing ₹69,342 crore, with 278 km commissioned by March 2025.
  • The Bairabi–Sairang line (September 2025) brought rail close to Aizawl.
• Incentives for backward regions:
  • North-East: the North East Industrial and Investment Promotion Policy (NEIIPP, 2007) covered Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim and Tripura. It was followed by the North East Industrial Development Scheme (2017) and UNNATI (March 2024), worth ₹10,037 crore up to 2034.
  • Hill States: a Special Package Scheme for Himachal Pradesh, Uttarakhand and Jammu and Kashmir.

Schemes for Backward Areas

• Backward Regions Grant Fund (BRGF): it ran in 272 identified backward districts to redress imbalances.
  • It had two windows: a Development Grant and Capacity Building.
  • Central support ended from 2015–16, after the 14th Finance Commission raised the States’ share of taxes.
• Pradhan Mantri Khanij Kshetra Kalyan Yojana (PMKKKY): launched on 17 September 2015 for people and areas affected by mining, many of them tribal, through District Mineral Foundations.
  • Guidelines revised in January 2024 require at least 70% of funds to go to high-priority sectors.
• Aspirational Districts Programme (January 2018): 112 districts, and 117 since five West Bengal districts joined in June 2026, tracked by delta ranking on 49 indicators.
  • The Aspirational Blocks Programme (January 2023) carries the method down to 500 blocks, now 513.
• Purvodaya: the Union Budget of July 2024 announced this plan for Bihar, Jharkhand, West Bengal, Odisha and Andhra Pradesh.

Competitive Federalism

• It means competition among States in trade, investment and commerce.
• States compete to attract funds and investment, which encourages administrative efficiency and developmental activity.
• Public rankings, such as the SDG India Index, extend this competition to social outcomes.
  • Critics note that better-endowed States start ahead in such competition, so it can widen gaps unless transfers offset them.

Way Forward

• Location-specific action: India’s geographical diversity and different levels of development call for targeted action in less prosperous regions, so that each reaches a minimum acceptable level of prosperity.
• Civil society: it needs strengthening in these areas, since regions with higher social capital tend to develop more rapidly and sustainably.
• Regional strategies: NITI Aayog’s Three Year Action Agenda (2017–18 to 2019–20) set out specific action for North Himalayan States, North-Eastern States, coastal regions and islands, and desert and drought-prone areas, and these need diligent implementation.
