Why developing nations employ more people in primary sector economy?

Developing nations tend to employ more people in the primary sector of the economy primarily due to their reliance on agriculture, mining, and natural resource extraction for income and sustenance. Limited access to technology, capital, and education often restricts diversification into secondary and tertiary sectors. Additionally, a significant portion of the population may rely on subsistence farming or informal labor, which further perpetuates the prominence of the primary sector in these economies. As these nations grow and develop, there's potential for a shift towards more industrial and service-oriented job opportunities.
