Global Population Density – 2006 (people per squared kilometre) Many of the countries appear to have the majority of their population located around the coasts of their lands. This is most likely because of two reasons. The first is that they are located near water sources, which is essential for survival. The second is that in the age of discovery the main means of travel and trade supply was through ships. Being closer to the sea would give easier access to ships. The st Population distribution – 21 century only exception to this is India which appears to be so over-crowded that the whole of its land mass is covered with people. Another global trend is that the populations are distributed in clusters rather than spread evenly around each country. This also may be because it is easier for people to be near each other as they can buy food and other utensils without having to cross the planet (Most people are also very social creatures). There are many exceptions dotted all over each country except for Australia which is largely inhospitable at its epicenter. These exceptions are mainly due to faster transportation. Smaller communities dispersed throughout countries can obtain supplies and travel relatively quickly to larger population clusters with the invention of cars and buses.
