In modern economies, including India, the Services sector (also known as the tertiary sector) is typically the largest contributor to the Gross National Product (GNP) or Gross Domestic Product (GDP). This sector includes a wide range of activities such as finance, healthcare, education, IT, trade, transportation, and government services. While agriculture was historically the dominant sector, and industries grew significantly during industrialization, services have surpassed them in terms of contribution to national income in most developed and developing nations.
