Largest sector by GDP in Nigeria.

**The reasoning** Nigeria's economy has three major sectors, and understanding their **relative contributions to GDP** is key. As of recent data, the **Services sector** contributes approximately **50-55% of Nigeria's GDP**, making it the largest. This includes telecommunications, banking, trade, entertainment (like Nollywood!), and hospitality. Agriculture contributes about 25-30%, while manufacturing and mining (including oil) combine for the rest. Think of it this way: Nigeria's economy has shifted from being heavily agriculture-dependent decades ago to a **service-driven economy**, just like many developing nations modernizing. **Why the wrong options tempt you** - **Agriculture** feels right because Nigeria is known for farming and feeds itself, but it's second now by GDP value - **Manufacturing** seems important but remains underdeveloped in Nigeria (we import most finished goods) - **Mining** tricks you because oil is huge for exports, but it doesn't dominate *total GDP* anymore — services do **Quick takeaway** "Services run Nigeria's economy now — from your MTN airtime to GTBank to Nollywood, that's over half our GDP."
