The majority of the country's landmass is located in a high plateau, lying between 3,500 and 4,500 feet above sea level.  Its climate is tropical, and its rainy season lasts from October to April.  The Zambezi River, which is 1,650 mi miles long, making it the fourth-largest in the continent, begins in Zambia and flows into the Indian Ocean. 
Zambia is divided into nine provinces. These are the Central, Western, Southern, North-Western, Northern, and Eastern provinces, along with Copperbelt, Luapula, and Lusaka.  Each province is subdivided into 72 districts. 
As of a July 2007 estimate, Zambia has a total population of 11,477,447. This, however, changes constantly, due to the high mortality rates caused by AIDS.

Zambia is a predominantly Christian country, the Roman Catholic Church being the largest single denomination.  Other major religions include Hinduism, Islam, and indigenous beliefs.
