The southern region of Mali — particularly the areas around the capital Bamako and the cities of Ségou and Sikasso — is the most densely populated part of the country.
| Factor | Southern Mali | Central/Northern Mali |
|---|---|---|
| Climate | Sudanian (900–1,200 mm rain/yr) | Sahelian (400–600 mm) → Saharan (<100 mm) |
| Agriculture | Rainfed cereals, cotton, rice, mangoes, livestock | Pastoralism only; marginal farming |
| Water | Niger & Bani Rivers (inland delta at Ségou) | Seasonal wadis; deep aquifers |
| Infrastructure | Paved roads, rail (Dakar–Bamako), grid power | Few paved roads; limited services |
| Security | Relatively stable | Jihadist insurgency, banditry, displacement |
Climate, water, and security drive Mali's extreme north-south population gradient.
