Observing the production-related process in an economy carefully, it is clear that the productivity of labour is higher in manufacturing and service sectors as compared to agricultural sector. Due to this, the economic development of the country can be estimated by population distribution on the basis of occupation. In India also, almost 85% people were directly or indirectly engaged in agriculture. Countries, in which agriculture is the main occupation, are considered underdeveloped. According to economists, most of the Indian population was dependant upon agriculture during 1881 to 1951.
