Asia is Earth’s largest and most populous continent, located primarily in the Eastern and Northern Hemispheres. Asia covers an area of 44,579,000 square kilometres (17,212,000 sq mi), about 30% of Earth’s total land area and 8.7% of the Earth’s total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Asia is notable for not only its overall large size and population, but also dense and large settlements, as well as vast barely populated regions. Its 4.5 billion people constitute roughly 60% of the world’s population.
It’s easy to see why – a well preserved cultural heritage, open borders and efficient infrastructure makes visiting Europe a breeze, and rarely will you have to travel more than a few hours before you can immerse yourself in a new culture, and dive into a different phrasebook. Although it is the world’s smallest continent in land surface area, there are profound differences between the cultures and ways of life in its countries.
