After independence secondary sector or manufacturing sector became the most important in total production and employment. In the past 30 years, service sector has taken a lead in terms of total production and employment. However, tertiary sector is largely dependent on secondary sector. Goods produced need to be sold, marketed and distributed. Banking activities and insurance sector get a boost by an expanding secondary sector. All sector are inter-related and expansion or shrinking of one sector has effects on other sectors too. As of now primary sector is the leading employer followed by tertiary and secondary sectors in that order. In terms of share in GDP tertiary sector is the leading sector followed by primary and secondary sectors.
