Table 2Population and surface of Africa according to classifications of mega-cities, urban areas, and malaria-endemic transmission areas (2001)

Geographic unit Population (millions) Area (thousands of km2)
Africa 812.6* 30,313
Malaria-endemic area 601.7 (741.0%)† 15,156 (50.0%)‡
Urban Africa 306.7 (37.7%)* 518.3–776.0 (1.7%–2.6%)§
Urban malaria-endemic area 200.0 (24.6%) 330.5–492.8 (1.1%–1.6%)§
Megacities# 96.8 (11.9%)* 60.6 (0.18%)**
Megacities malaria-endemic area 60.5 (7.4%)†† 25.01 (0.08%)**
*

Based on the UN World Urbanization Prospects, 2001.7

Based on calculations given by Snow and others34 and the growth rate from UN World Urbanization Prospects, 2001.

The total area of endemic places was computed from MARA maps available at http://www​.mara.org.za.

§

Area estimated by nighttime satellite images (see Materials and Methods for further details).

Comparing population density maps and malaria transmission maps (urban inhabitants excluding South Africa, Botswana, Namibia, northern Africa, Somalia, and Djibouti), as described in the Materials and Methods.

#

Defined as areas with 750,000 or more inhabitants.

**

Area estimated from administrative boundaries from megacities.

††

All megacities excluding those located in northern Africa and South Africa.
