Executive Summary
Tamil Nadu has transformed from an agrarian economy in 1950 to India’s second-largest state economy by 2023–24, with a GSDP of ₹31 lakh crore and a per capita income (₹3,15,220) 1.71 times the national average. Its diversified economy—spanning automotive, textiles, electronics, IT, and sustainable agriculture—is underpinned by a 48.4% urbanization rate, 80.3% literacy, and a 6.5% poverty rate. Compared to Maharashtra, Gujarat, Karnataka, AP, and India, Tamil Nadu excels in social indicators (HDI: 0.708) and diversification, trailing Maharashtra in GSDP scale and Karnataka in IT dominance. Dravidian social reforms, the Green Revolution, post-1991 liberalization, and the 2021 Industrial Policy were pivotal. State budgets show opportunities in infrastructure and renewables but face constraints from welfare spending (40%) and debt (25% GSDP). Projected GSDP growth of 8–9% through 2025 hinges on electronics, IT, and green energy, leveraging strengths like a skilled workforce and coastal ports. Reforms in labor laws, rural industrialization, and sustainability are critical to capitalize on opportunities like global supply chains and digital transformation, positioning Tamil Nadu competitively against peers.
