In recent decades, especially between 1973-74 and 2013-14, the tertiary sector in India has grown substantially, becoming the largest contributor to the country's GDP. This growth can be attributed to several factors: the essential services provided by government (e.g., health, education, security), the rising demand for various services in urban areas due to increasing income levels, and the emergence of new sectors driven by technology. However, despite the tertiary sector's expansion in GDP, employment did not experience a corresponding increase, with a majority still employed in agriculture due to underemployment. This section explores these dynamics, illustrating the crucial role of the service sector while also recognizing the challenges faced by workers in unorganized sectors.
