1. Population Explosion:
The most fundamental cause of large scale unemployment in India is the high rate of population growth since the early 1950s and the consequent increase in its labour force. It was estimated that with the 2.5 per cent annual rate of population growth, nearly 4 million persons are added to the labour force every year. To provide gainful employment to such a big number is really a difficult task.
2. Slow Rate of Growth:
In India the rate of growth of the economy is very poor and even the actual growth rate lies always far below the targeted rate. Thus, the increased employment opportunities created under the successive plans could not keep pace with the additions to the labour force taking place in the country every year leading to a huge and larger backlog of unemployment at the end of each plan.
3. Backwardness of the Agriculture:
Heavy pressure of population on land and the primitive methods of agricultural operations are responsible for colossal rural unemployment and underemployment in the country.
4. Insufficient Industrial Development:
Industrial development in the country is not at all sufficient. Rather the prospects of industrial development have never been completely realized. Due to dearth of capital, lack of proper technology, scarcity of industrial raw materials, shortage of electricity and lack of labour intensive investment, industrial sector could not gain its momentum and also could not generate sufficient employment opportunities in the country.
5. Prevailing Education System:
The prevailing education system in India is full of defects as it fails to make any provision for imparting technical and vocational education. Huge number of matriculates, undergraduates and graduates are coming out every year leading to a increasing gap between job opportunities and job seekers among the educated middle-class.
