The Nine States of Nigeria's Niger Delta Region

The Niger Delta comprises nine states (not ten):

1. Abia
2. Akwa Ibom
3. Bayelsa
4. Cross River
5. Delta
6. Edo
7. Imo
8. Ondo
9. Rivers

These states produce the bulk of Nigeria's oil and gas; the region faces environmental degradation, militancy, and development challenges.
