Earth is divided into a Northern and Southern Hemisphere at the Equator, the imaginary line on the planet midway between its geographical poles.

Geographic Overview

The Southern Hemisphere is the half of Earth south of the Equator, containing 80.9% water (20% more than the Northern Hemisphere) from four oceans, including the Indian, South Atlantic, Southern, and South Pacific). Because the Southern Hemisphere has significantly more ocean and less land, climates tend to be milder than similar latitudes in the Northern Hemisphere. This is because water heats up and cools more slowly than land.

Regarding land, the Southern Hemisphere contains all or a portion of five continents, including:

Population Overview

The population of the Southern Hemisphere is 800 million, only 10-12% of the total population of 7.3 billion. Two hundred million of these 800 million live in Brazil, the largest and most densely populated country in the Southern Hemisphere. Another 141 million live on the Indonesian island of Java, the most populous island in the world. Because of the Southern Hemisphere demographics, Portuguese is the most spoken language, followed by Spanish and Javanese. Countries in the Southern Hemisphere are located in both the Eastern Hemisphere and the Western Hemisphere.
