Workers in different sectors (in millions)
(a) Primary sector and especially the unorganised is providing most jobs to the people.
(b) 370 millions.
(c) Employment opportunities in the organised sector have been expanding very slowly. Therefore a large number of workers are forced to enter the unorganised sector jobs, which pay a very low salary.
(d) Tertiary sector is the most important organised sector. Because as income levels rise, certain sections of people start demanding more services like tourism, shopping, private schools, etc. Production in tertiary sector is rising day by day.
