The industry sector—which includes manufacturing, mining, and construction—follows as the second-highest contributor.
Agriculture—comprising farming, fishing, and forestry—comes in third, playing a significant but smaller role in overall GDP composition.

Africa is not left behind in this trend. The continent’s services sector now contributes over 50% of its GDP, signaling a strong shift toward economic diversification.

Key contributors to this shift include:

Fintech & mobile money
E-commerce
Telecom & digital infrastructure
Urbanization and youth-driven innovation

Countries like Nigeria, Kenya, South Africa, Egypt, and Ghana are leading the way, driven by mobile connectivity and tech startups revolutionizing everything from banking to logistics.

The IMF data highlights a global transition toward service-based economies. This shift has major implications for policy, investment, and workforce development, especially in emerging markets like Africa.

As nations evolve, the service sector’s role in shaping economic resilience and growth becomes even more vital—setting the pace for future prosperity.
