Indian Economy 1950-1990 — Economics STD 12 Humanities & Commerce — Question

There has not been a marked change in the occupational pattern during the initial stages of planning. Agriculture and allied activities continued to absorb about 66.8 percent of the working force.
The secondary sector accounted for 12.7 percent and tertiary sector accounted for about 20.5 percent of the working population.
This means that the secondary and service sectors had not grown rapidly enough to make an impact on the occupational structure.
The primary sector was also not able to create surpluses enough to create conditions for expansion elsewhere.
