Tamil Nadu possesses one of the largest and most diverse economies in India, consistently ranking among the top two states by Gross State Domestic Product (GSDP). It is a heavily industrialized state with a strong manufacturing base, accounting for a significant portion of India's exports in automobiles, textiles, and leather goods.
The state has also emerged as a leading destination for IT and ITeS (Information Technology Enabled Services) investments, second only to Karnataka in software exports. Additionally, Chennai is known as the "Health Capital of India," drawing medical tourists from across the globe. While major cities exhibit a rising cost of living reflective of a booming middle class, median incomes in urban areas are relatively high compared to the national average, supported by abundant employment opportunities in technology, manufacturing, and services.
