Primary sector continues to be the largest employer because:

1) Enough jobs have not been created in other sectors.

2) Primary sector requires comparatively less education than the other two sectors.

3) Most of the unemployed people take up activities of primary sector in hope of earning some money

while Tertiary sector contributes the largest in terms of share in GDP in India. The sector is also the service sector and is important when you consider the development of the other two sectors. Like the previous sector, this sector also adds the value to the products. This sector is responsible for employing 23 percentage of the workforce out of the total workforce currently working in India.

Introduction:
The economy of a country is broadly classified into three sectors, namely primary, secondary, and tertiary sectors. The primary sector includes agriculture, fishing, mining, and other natural resource-based industries. The secondary sector includes manufacturing and construction industries, while the tertiary sector includes services such as healthcare, education, finance, transportation, and other service-based industries.

Employment in Primary Sector:
The primary sector employs the largest number of people, especially in developing countries. In India, for example, more than half of the workforce is employed in the agricultural sector. Similarly, in other developing countries, the primary sector is the largest employer, providing employment to millions of people.

GDP Contribution of Tertiary Sector:
However, despite employing fewer people, the tertiary sector contributes more to the GDP of a country. This is because the services provided by the tertiary sector are more valuable and have a higher price compared to the products of the primary sector. For instance, the healthcare sector provides valuable services that are essential for the well-being of the population. Similarly, the education sector provides the necessary skills and knowledge required for the growth and development of the country.

Factors Affecting the GDP Contribution:
The contribution of the tertiary sector to the GDP of a country depends on several factors such as the level of development, the size of the population, and the government policies. In developed countries, the tertiary sector is the largest contributor to the GDP, while in developing countries, the primary sector is the largest contributor. However, with the growth of the economy, the tertiary sector gradually becomes the dominant sector, contributing more to the GDP.

Conclusion:
In conclusion, while the primary sector employs more people, the tertiary sector contributes more to the GDP of a country. The economic growth of a country depends on the development of all three sectors, and the government should focus on policies that promote the growth of all sectors.
