BharatNotes Regional Disparities in India — The Core Problem
India exhibits some of the widest inter-state economic disparities of any large federal democracy. Understanding these disparities is central to GS-3 questions on inclusive growth and regional development.
Per Capita Income Variation Across States
| Category | States | Per Capita NSDP Range |
|---|---|---|
| Highest | Goa, Sikkim, Delhi, Haryana, Karnataka | Rs 3–5 lakh and above |
| Middle | Gujarat, Tamil Nadu, Maharashtra, Telangana, Himachal Pradesh, Uttarakhand | Rs 2–3.5 lakh |
| Lowest | Bihar, Jharkhand, Uttar Pradesh, Madhya Pradesh, Assam | Rs 0.7–1.5 lakh |
Key observations:
- Delhi tops per capita NSDP at approximately Rs 4.93 lakh, while Bihar records the lowest at approximately Rs 69,321 — a ratio of roughly 7:1.
- Smaller, specialised states and UTs (Sikkim, Goa, Chandigarh) lead per capita rankings due to small populations combined with niche economic advantages (tourism, hydropower, services).
- Large, populous states (UP, Bihar, MP) have high absolute GSDP but low per capita income — reflecting the burden of large populations on limited economic output.
Dimensions of Regional Disparity
| Dimension | Indicator | Disparity Pattern |
|---|---|---|
| Income | Per capita GSDP | 7:1 ratio between richest and poorest states |
| Poverty | Multidimensional Poverty Index | Bihar, Jharkhand, UP have highest headcount ratios; Kerala, Goa, Tamil Nadu lowest |
| Health | Infant mortality rate, maternal mortality | High in MP, UP, Assam, Odisha; low in Kerala, TN, Delhi |
| Education | Literacy, years of schooling | Bihar (61.8% literacy) vs Kerala (96.2%) |
| Infrastructure | Road density, power availability, internet penetration | North-East, eastern UP, central India lag behind |
| Urbanisation | Share of urban population | Goa, Delhi, Tamil Nadu highly urbanised; Bihar, Assam, HP largely rural |
Causes of Regional Disparity
| Factor | Explanation |
|---|---|
| Geography | Hilly/remote terrain (North-East, J&K, Himachal) increases cost of infrastructure; flood-prone areas (Bihar, Assam) face recurring setbacks |
| Historical neglect | Colonial-era infrastructure concentrated in port cities (Mumbai, Kolkata, Chennai); interior districts remained neglected |
| Resource endowment | Mineral-rich states (Jharkhand, Odisha, Chhattisgarh) have not always translated resource wealth into human development |
| Governance quality | States with better institutions, lower corruption, and consistent policy attract more investment |
| Demographic pressure | High population growth in Bihar, UP, MP dilutes per capita gains from economic growth |
| Private investment patterns | Industry clusters in Gujarat, Maharashtra, TN, Karnataka — creating self-reinforcing agglomeration effects |
Policy Approaches to Reducing Regional Disparities
| Approach | Mechanism | Examples |
|---|---|---|
| Fiscal transfers | Finance Commission recommendations — tax devolution and grants to lagging states | 15th FC: 41% vertical devolution; income distance (45% weight) favours poorer states |
| Centrally Sponsored Schemes (CSS) | Higher central share for poorer/special category states | 90:10 Centre-state ratio for NE and hill states vs 60:40 for others |
| Area development programmes | Targeted schemes for backward/aspirational regions | ADP, Aspirational Blocks Programme, BRGF (discontinued) |
| Special category status | Enhanced central assistance to states with structural disadvantages | 11 NE and hill states |
| Industrial incentives | Tax holidays, capital subsidies for industries in backward regions | North-East Industrial Development Scheme (NEIDS) |
| Infrastructure push | Targeted road, rail, digital connectivity for lagging regions | PM GatiShakti, BharatNet, Sagarmala |
Finance Commission and Regional Equity
The Finance Commission is the constitutional body (Article 280) that recommends distribution of tax revenues between the Centre and states, and among states.
15th Finance Commission (2021-22 to 2025-26)
| Parameter | Detail |
|---|---|
| Chairman | N.K. Singh |
| Vertical devolution | 41% of divisible pool of central taxes to states (Rs 42.2 lakh crore for 2021-26 period) |
| Horizontal devolution formula | Income Distance: 45%; Population (2011): 15%; Area: 15%; Demographic Performance: 12.5%; Forest & Ecology: 10%; Tax & Fiscal Efforts: 2.5% |
| Income distance | Largest weightage (45%) — measured as distance of a state's per capita income from the state with the highest per capita income; favours poorer states significantly |
| Demographic performance | New criterion (12.5%) — rewards states that have controlled population growth (benefits southern and smaller states) |
| Grants to local governments | Rs 4.4 lakh crore for 2021-26 period |
| Performance-based grants | Rs 45,000 crore for agricultural reforms; Rs 4,800 crore for educational outcomes |
16th Finance Commission
| Feature | Detail |
|---|---|
| Chairman | Arvind Panagariya |
| Period covered | 2026-27 to 2030-31 |
| Key issues | Vertical devolution ratio; updated horizontal formula; Census 2011 vs Census 2021 population data; role of demographic performance criterion |
How the Finance Commission Reduces Disparities
- Income distance criterion ensures that states with lower per capita income receive a larger share of taxes.
- Grants (revenue deficit grants, sector-specific grants, disaster management grants) provide additional support.
- Equalisation principle — the Commission aims to enable all states to provide comparable levels of public services at comparable tax effort.
Special Category States
| Feature | Detail |
|---|---|
| Origin | Concept introduced by the 5th Finance Commission (1969) based on recommendations of the National Development Council |
| Criteria | (i) Hilly and difficult terrain; (ii) Low population density or large tribal population; (iii) Strategic border location; (iv) Economic and infrastructural backwardness; (v) Non-viable nature of state finances |
| Current states | 11 states — all 8 North-Eastern states (Assam, Arunachal Pradesh, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim, Tripura) + Himachal Pradesh, Uttarakhand, and Jammu & Kashmir |
Benefits of Special Category Status
| Benefit | Detail |
|---|---|
| CSS funding ratio | 90:10 (Centre : State) vs 60:40 for general category states |
| Tax concessions | Historically received excise duty and income tax exemptions for industries |
| Plan assistance | 30% of gross budgetary support was earmarked for special category states (prior to abolition of Planning Commission) |
| Debt and grant ratio | Received 90% of central assistance as grants and only 10% as loans (vs 30:70 for general states) |
Post-14th Finance Commission Changes
The 14th Finance Commission (Chairman: Y.V. Reddy) significantly increased the vertical devolution from 32% to 42%. It recommended that the distinction between Plan and non-Plan expenditure, and between general and special category states, be done away with. The rationale: higher tax devolution and formula-based grants (using backwardness criteria) would automatically channel more resources to poorer states. As a result, the traditional model of special category plan assistance became largely obsolete, though the special status label and CSS funding ratios continue.
Aspirational Districts Programme (ADP)
| Feature | Detail |
|---|---|
| Launched | January 2018 by the Prime Minister |
| Districts covered | 112 most under-developed districts across 27 states |
| Anchored by | NITI Aayog |
| Guiding principles | 3 Cs — Convergence (of central and state schemes), Collaboration (between central, state officials, and district collectors), Competition (among districts through delta ranking) |
Five Thematic Areas and Key Performance Indicators (KPIs)
| Theme | Example Indicators | Weight |
|---|---|---|
| Health & Nutrition | Institutional deliveries, immunisation, treatment success rate (TB), stunting | High |
| Education | Learning outcomes, transition rates, teacher availability, infrastructure | High |
| Agriculture & Water Resources | Micro-irrigation coverage, soil health cards distributed, water body rejuvenation | Medium |
| Financial Inclusion & Skill Development | PM Mudra accounts, insurance penetration, PMKVY enrolments | Medium |
| Basic Infrastructure | Road connectivity, electrification, individual household latrines, internet access | Medium |
Delta Ranking System
| Feature | Detail |
|---|---|
| Concept | Districts ranked not on absolute performance but on incremental improvement (delta) over time — rewards effort, not legacy advantage |
| Frequency | Monthly rankings (2018-2024); shifted to quarterly rankings from April 2025 under ADP Phase III |
| Dashboard | Champions of Change Dashboard — real-time tracking across 49 KPIs |
| Data source | Self-reported district data verified through third-party validation |
| Award cycle | Quarterly awards under ADP Phase III (FY 2024-25 and 2025-26) |
Selection Methodology for the 112 Districts
Districts were identified by a committee of secretaries using a composite index based on:
- Deprivation across health, education, and infrastructure parameters
- Low per capita income
- Presence in Left Wing Extremism (LWE) affected areas
- High proportion of SC/ST population
- Proximity to international border
Impact and Outcomes
The ADP model is considered a success in competitive federalism — districts that were at the bottom of development indices have shown measurable improvement in health, education, and infrastructure indicators. The programme has been studied by the UNDP and World Bank as a model for sub-national targeted development.
Aspirational Blocks Programme (ABP)
| Feature | Detail |
|---|---|
| Launched | 7 January 2023 by the Government of India |
| Blocks covered | 500 blocks across 329 districts in 27 states and 4 UTs |
| Overlap with ADP | 160 of the 500 blocks are in the 112 Aspirational Districts |
| Anchored by | NITI Aayog in coordination with central ministries, state and UT governments, and district administration |
| KPIs | 39 indicators across 5 themes — Health & Nutrition, Education, Agriculture & Allied Services, Basic Infrastructure, and Social Development |
| Ranking | Block-level delta ranking; quarterly ranking with awards |
| Rationale | District is too large a unit for targeted intervention — intra-district disparities can be addressed by focusing on the most lagging blocks |
Backward Region Grant Fund (BRGF)
| Feature | Detail |
|---|---|
| Launched | 19 February 2007 by Prime Minister Manmohan Singh at Barpeta, Assam |
| Ministry | Ministry of Panchayati Raj |

| Objective | Fill critical gaps in development not adequately met by sector-specific programmes; strengthen local governance capacity |
| Components | (i) Development Grant and (ii) Capacity Building Component |
| Current status | Discontinued from 2015-16 — delinked from central budgetary support following implementation of 14th Finance Commission recommendations (higher tax devolution was seen as an adequate substitute) |
North-East Development — Special Packages and Schemes
The North-Eastern Region (NER) — 8 states — receives special attention due to geographical isolation, difficult terrain, ethnic diversity, and strategic border location.
Key Institutional Framework
| Institution | Role |
|---|---|
| Ministry of Development of North Eastern Region (MDoNER) | Nodal ministry for NE development; coordinates with central ministries |
| North Eastern Council (NEC) | Statutory body (NEC Act, 1971; amended 2002) — regional planning body for NE states |

| Focus areas | Infrastructure (roads, bridges, helipads), social infrastructure (schools, health centres), livelihood, skill development |
| Special focus | Zero-line villages (villages closest to the international border) |
NITI Aayog Composite Indices for Competitive Federalism
NITI Aayog publishes several indices to promote data-driven governance and healthy competition among states and districts.
| Index | Purpose | Key Feature |
|---|---|---|
| SDG India Index | Measures state and UT progress on Sustainable Development Goals | First government-led subnational SDG measure in the world; launched December 2018 |
| National Multidimensional Poverty Index (MPI) | Measures poverty across health, education, and standard of living (12 indicators) | India's MPI declined from 29.17% (2013-14) to 11.28% (2022-23) — 24.82 crore people escaped multidimensional poverty |
| Composite Water Management Index | Assesses state-level water management performance | Highlights water stress variation across states |
| Health Index | Measures health outcomes, governance, and key inputs | Produced in collaboration with World Bank |
| School Education Quality Index (SEQI) | Evaluates learning outcomes and access | Ranks states on education quality, not just enrolment |
| Export Preparedness Index | Measures states' readiness for export promotion | Helps identify infrastructure and policy gaps |
| Innovation Index | Ranks states on innovation ecosystem | Based on inputs (human capital, institutions) and outputs (knowledge, business sophistication) |
National MPI — Key Data
| Indicator | 2013-14 | 2022-23 | Change |
|---|---|---|---|
| Headcount ratio (H) | 29.17% | 11.28% | -17.89 percentage points |
| People lifted out of poverty | — | 24.82 crore | Over 9 years |
| Best-performing states | — | Kerala, Goa, Tamil Nadu, Sikkim | Lowest MPI values |
| Worst-performing states | — | Bihar, Jharkhand, Meghalaya, UP | Highest MPI values (though declining) |
India is likely to achieve SDG Target 1.2 (halving multidimensional poverty) well before 2030.

Recent Developments (2024–2026)
16th Finance Commission — Arvind Panagariya and Key Issues
The 16th Finance Commission (Chairman: Arvind Panagariya) was constituted in December 2023 for the award period 2026-27 to 2030-31. Key issues being examined: (1) whether to update horizontal formula with Census 2021 population data (vs continuing with Census 2011), which could shift allocations towards southern states with slower population growth; (2) the demographic performance criterion — should states that controlled population growth continue to be rewarded; (3) the appropriate vertical devolution ratio (above or below the 15th FC's 41%); (4) GST compensation cess expiry and fiscal adjustment. The Commission is expected to submit its report by October 2025.
UPSC angle: 16th Finance Commission (Arvind Panagariya, 2026-31), Census 2011 vs 2021 population data debate, demographic performance criterion retention, and vertical devolution ratio are active policy debates for Mains GS3 fiscal federalism and regional disparity themes.
Aspirational Blocks Programme — 2024-25 Progress and Delta Rankings
The Aspirational Blocks Programme (ABP), launched January 7, 2023 covering 500 blocks in 329 districts across 27 states and 4 UTs, has progressed significantly. 160 of the 500 blocks overlap with the 112 Aspirational Districts. ABP uses 39 indicators across 5 themes with quarterly delta rankings — the same competitive federalism model as ADP. The Champions of Change Dashboard tracks block-level incremental progress in real-time. In FY 2024-25, the ADP also shifted to quarterly (vs monthly) ranking cycles under Phase III.
UPSC angle: ABP (launched January 7, 2023; 500 blocks; 39 KPIs; 27 states + 4 UTs; 160 blocks overlap with ADP districts) and ADP Phase III quarterly ranking are current data points for Prelims distinction questions (ADP vs ABP).
PM-DevINE and North-East Development
PM-DevINE (PM's Development Initiative for North East Region), approved in 2022-23 with an outlay of Rs 6,600 crore (2022-23 to 2025-26), is 100% centrally funded and implemented through MDoNER/NEC. It focuses on: infrastructure (roads, ropeways), livelihoods for youth and women, and social development. The North Eastern Council (NEC), established under the NEC Act 1971, received Rs 3,202.7 crore in schemes allocation. All central ministries must earmark 10% of Gross Budgetary Support (GBS) for the North Eastern Region — a structural mechanism for regional equity.
UPSC angle: PM-DevINE (Rs 6,600 crore, 100% central funding, 2022-26), NEC statutory body (NEC Act 1971), and 10% GBS earmarking for NER are Prelims facts. The NE's development gap despite resource endowment is a Mains GS3 regional development theme.
