Tamil Nadu Economy – GSDP & Growth, Per Capita Income, Sectors, Industrial Clusters & MSMEs, Urbanisation, SDG & Poverty Indices, $1 Trillion Target | TNPSC Notes

Tamil Nadu's economy is the second-largest State economy in India after Maharashtra. As per the RBI Handbook of Statistics on Indian States 2024-25 and the Tamil Nadu Economic Survey 2025-26, its Gross State Domestic Product (GSDP) at current prices was about Rs 31.2 lakh crore in 2024-25, and as per MoSPI its real growth that year was 11.19%, the highest among the major States. With about 4% of India's land and 6% of its people, it produces about 9% of India's GDP, leads the country in the number of factories and electronics exports, is the most urbanised large State (Census 2011) and is among the best performers in NITI Aayog's SDG India Index and Multidimensional Poverty Index.

These notes are written for TNPSC Group 1, 2/2A and 4 aspirants and are meant to be complete on their own. The topic is a core part of Indian Economy and Development Administration in Tamil Nadu (State income, sectors, industry, MSMEs, poverty, human development, social and economic indicators). Industrial clusters and urbanisation are also asked under Geography of India (economic geography of Tamil Nadu), and new survey numbers, index ranks and budget targets are asked under Current Events. Every figure below is given with its year and source, because examiners often change the year in the options. Read each section, then use the tables, the quick revision table and the key points at the end.

Tamil Nadu Economy at a Glance

Background: Key Terms and Data Sources

Before learning the numbers, be clear about what each indicator measures and who publishes it. TNPSC questions often test the difference between these terms.

• GSDP (Gross State Domestic Product): the value of all final goods and services produced within the State in a year. It is the State-level version of GDP.
• GSVA (Gross State Value Added): output minus inputs, measured sector-wise (agriculture, industry, services). Sector shares are worked out from GSVA, not GSDP.
• NSDP and per capita income: Net State Domestic Product (GSDP minus depreciation) divided by the population gives per capita NSDP, generally called per capita income. Per capita GSDP is a different, higher number.
• Current prices vs constant prices: current-price (nominal) figures include inflation; constant-price (real) figures use the prices of a base year. State accounts in these notes use the 2011-12 base. 'Real growth' always means growth at constant prices.
• Who publishes: the Department of Economics and Statistics (DES), Tamil Nadu prepares the State's income estimates; MoSPI (National Statistics Office) publishes them for all States; the RBI Handbook of Statistics on Indian States compiles them each year; the Tamil Nadu Economic Survey (from 2025) and the State Budget give the State's own analysis; NITI Aayog publishes the SDG India Index, the Multidimensional Poverty Index and the Export Preparedness Index; the Census (latest completed: 2011) gives population and urbanisation.

GSDP: Size, Growth and Rank

• Size: GSDP at current prices was about Rs 31.2 lakh crore in 2024-25 (RBI Handbook 2024-25: Rs 31.18 lakh crore; Economic Survey 2025-26: Rs 31.19 lakh crore), up from about Rs 26.9 lakh crore in 2023-24 (RBI Handbook).
• Nominal growth: about 16% in 2024-25 (RBI Handbook: 15.98%).
• Real growth: 11.19% in 2024-25 as per MoSPI estimates released in August 2025 – the highest among the major States and the State's first double-digit real growth in more than a decade. The Economic Survey 2025-26 rounds this to 11.2%.
• Rank: Tamil Nadu is the second-largest State economy; Maharashtra is first (RBI Handbook 2024-25).
• Share of India: about 9% of India's GDP – the first Economic Survey put it at 9.21% for 2023-24 and the second at 9.4% for 2024-25 – from about 4% of the land area and 6% of the population.
• Drivers in 2024-25: the Economic Survey 2025-26 credits growth mainly to the secondary sector; manufacturing grew by more than 14% in real terms, along with strong services growth.

Exam tip: 11.19% is the real growth rate; about 16% is the nominal growth rate of the same year. Do not mix them up.

Per Capita Income

• 2024-25: per capita income (per capita NSDP at current prices) was Rs 3,61,619 as per the RBI Handbook 2024-25; the Economic Survey 2025-26 gives it as Rs 3.62 lakh, against a national average of about Rs 2.05 lakh.
• Rank: the Economic Survey 2025-26 places Tamil Nadu third among large States in per capita income (2024-25). Small States and Union Territories such as Delhi and Goa have higher figures, so always read whether the question says 'large States' or 'all States/UTs'.
• Earlier: the first Economic Survey reported Rs 2.78 lakh in 2022-23, when Tamil Nadu was fourth among major States, after Telangana, Karnataka and Haryana.

Sectoral Composition of the Economy

Tamil Nadu has a services-led economy with a large manufacturing base. The shares of Gross State Value Added (GSVA) at current prices in 2024-25 were:

• Source: Tamil Nadu Economic Survey 2025-26, matching MoSPI State-wise GSVA data (services 53.60%, secondary 33.05%, primary 13.35%).
• The first Economic Survey also showed a similar pattern for 2022-23 – secondary sector about 33% and primary sector about 13%, with services the largest.
• A secondary-sector share of about one-third is high among Indian States and reflects Tamil Nadu's manufacturing strength.

Industry and Manufacturing

The Annual Survey of Industries (ASI) of MoSPI covers registered factories. Its results for 2024-25 were released on 30 September 2026.

• Tamil Nadu was also first in both the number of factories and factory employment in ASI 2023-24.
• Remember the pattern: Tamil Nadu leads in count of factories and jobs (many small and medium units), while Maharashtra and Gujarat lead in value added (larger capital-intensive units such as refineries and chemicals).

Industrial Clusters of Tamil Nadu

An industrial cluster is a group of firms in one area that share a common market, skills and technology. The Class 10 Social Science textbook of Tamil Nadu describes the following major clusters.

• Public sector base: Integral Coach Factory (Chennai), BHEL (Tiruchirappalli), Heavy Vehicles Factory (Avadi) and Salem Steel Plant laid the early industrial base.
• Export zone: the Madras Export Processing Zone (MEPZ) at Tambaram was set up in 1984; many SEZs, including IT SEZs, came up later around Chennai.
• Three phases (textbook): the colonial phase (cotton, textiles, ports at Chennai and Thoothukudi); the post-Independence phase up to the early 1990s (public sector units, industrial estates, textile clusters); and the post-liberalisation phase (export growth, multinational automobile and electronics firms, SEZs).

Electronics and Exports

• Electronics exports: Tamil Nadu's electronics exports were USD 14.65 billion in 2024-25, up from USD 9.56 billion in 2023-24, making it India's largest electronics-exporting State with about 41% of the national total.
• Export Preparedness Index 2022: in this NITI Aayog index (third edition, released in July 2023) Tamil Nadu was ranked first, ahead of Maharashtra, Karnataka and Gujarat.
• Mobile phones made in the Chennai region are a major part of these electronics exports.

Micro, Small and Medium Enterprises (MSMEs)

MSMEs are the backbone of Tamil Nadu's clusters – knitwear units in Tiruppur, foundries and pump makers in Coimbatore, fireworks units in Sivakasi and auto-component suppliers around Chennai and Hosur.

• Registration: MSMEs register on the Union Government's Udyam portal, which began on 1 July 2020. Tamil Nadu is among the top three States in Udyam registrations, along with Maharashtra and Uttar Pradesh (MSME Ministry data in Parliament, December 2025; Udyam-based industry reports).
• State support: the State has a separate MSME Department, and agencies such as TIIC and SIPCOT (below) support small and large units.

The earlier limits (from 1 July 2020) were Rs 1 crore / Rs 5 crore for micro, Rs 10 crore / Rs 50 crore for small and Rs 50 crore / Rs 250 crore for medium enterprises.

Industrial Promotion Agencies and Investment

• Global Investors Meet 2024: held in Chennai on 7–8 January 2024; MoUs worth about Rs 6.64 lakh crore were signed, with about 26.9 lakh jobs expected.

Urbanisation and Population (Census 2011)

• Most urbanised large State: Tamil Nadu ranks first among large States in the share of urban population. Among all States, Goa (62.17%) and Mizoram (52.11%) are ahead, and Kerala (47.70%) is just behind.
• The provisional Census figure was 48.45%; the final figure is 48.40%.
• High urbanisation goes with the spread of manufacturing and services beyond Chennai to cities such as Coimbatore, Madurai, Tiruchirappalli, Salem and Tiruppur.

Human Development: TNHDR 2017 and the SDG India Index

The Government of India does not publish an annual official Human Development Index (HDI) for States. The official measures used in exams are the State's own Human Development Report and NITI Aayog's SDG India Index.

• Tamil Nadu Human Development Report 2017 (State Planning Commission; the earlier report was of 2003) ranked districts by HDI: Kanniyakumari first, followed by Virudhunagar, Thoothukudi, Chennai and Kancheepuram; Ariyalur was last.
• SDG India Index 2023-24 (fourth edition, NITI Aayog, released on 12 July 2024): Tamil Nadu scored 78 and was third. Kerala and Uttarakhand were joint first (79), Goa scored 77 and Bihar was last (57). India's composite score rose to 71 from 66 in 2020-21.

Poverty: NITI Aayog Multidimensional Poverty Index

The Multidimensional Poverty Index (MPI) measures deprivation in three dimensions – health, education and standard of living – using 12 indicators from the National Family Health Survey (NFHS).

Note: in the 2023 Progress Review the 2015-16 figure for Tamil Nadu was revised to 4.76%, so the fall is shown as about 2.6 percentage points. Nationally, the 2023 review estimated that about 13.5 crore people moved out of multidimensional poverty between 2015-16 and 2019-21.

The Tamil Nadu Economic Survey

• Both surveys were prepared by the State Planning Commission with the Finance Department and released before the Budget, following the practice of the Union Economic Survey.
• Note the wording: it was Tamil Nadu's own first Economic Survey. Several other States had published economic surveys before 2025.

The Trillion-Dollar Target

At about Rs 31.2 lakh crore, the 2024-25 GSDP is roughly a third of the way to USD 1 trillion in dollar terms, so the target depends on sustained double-digit nominal growth and on the rupee–dollar exchange rate.

• TNHDR 2017: Kanniyakumari first and Ariyalur last among districts – shows intra-State gaps to be addressed.

Practice: Match the Following

Common Mistakes to Avoid

• Real vs nominal growth: 11.19% is real growth (2024-25); about 16% is nominal growth.
• Largest State economy: Maharashtra is first; Tamil Nadu is second.
• ASI ranks: Tamil Nadu is first in number of factories and employment, but third in manufacturing GVA.
• Most urbanised: Tamil Nadu is first among large States; Goa has the highest urban share among all States. Final Census figure is 48.40%, not the provisional 48.45%.
• SDG India Index 2023-24: Tamil Nadu was third (78); Kerala and Uttarakhand were first (79).
• MPI years: 2.20% is for 2019-21 (NFHS-5); 4.89% was the 2015-16 figure in the 2021 baseline report.
• Per capita income vs per capita GSDP: Rs 3.62 lakh is per capita NSDP (income) for 2024-25; per capita GSDP is a higher figure.
• Trillion-dollar years: 2030 was the original target; 2031 is the Economic Survey 2025-26 estimate; USD 1.5 trillion by 2036 is the Budget 2026-27 goal.
• First Economic Survey: 2024-25 survey, released in March 2025 – Tamil Nadu's first, not India's first State survey.
