Most earthlings, about 90% live in the northern hemisphere.Also, 80% of the population is concentrated in the eastern hemisphere, against 20% in the west, while 60% of people - Asians (on average - 109 people. / Km2).For 7% of the planet is concentrated about 70% of the population.A 10-15% of the land, and all are uninhabited territory - a land of Antarctica, Greenland, etc.

population density of the countries

In the world there are countries with both low, so high levels of population density.The first group includes, for example, Australia, Greenland, Guyana, Namibia, Libya, Mongolia, Mauritania.The population density in them no more than two people per square kilometer.

in Asia are the most densely populated countries - China, India, Japan, Bangladesh, Taiwan, South Korea and others.The average population density in Europe - 87 people. /
Km2 in America - 64 people. / Km2, Africa, Australia and Oceania - 28 people. / Km2 and 2.05 pers. / Km2, respectively.

States with a small area is usually very densely populated.This, for example, Monaco, Singapore, Malta, Bahrain, Republic of Maldives.

Among the cities with the highest population density can be distinguished Egyptian Cairo (36,143 pers. / Km2), the Chinese Shanghai (2683 pers. / Km2 for 2009), Pakistan Karachi (5139 pers. / Km2), Turkey Istanbul (6521 persons. / km2), Tokyo, Japan (5740 pers. / km2), Indian Mumbai and Delhi, Buenos Aires, Argentine, Mexico Mexico City, the capital of Russia Moscow (10 500 people. / km2), etc.

reasons for the uneven settling

uneven settling of the planet is due to different factors.First of all, it's natural and climatic conditions.Half of earthlings living in the lowlands, which constitute less than a third of land, one third of people living from the sea at a distance of no more than 50 kilometers (12% of the land).

traditional zone with adverse and extreme natural conditions (high mountains, tundra, desert, tropics) settled inactive.

Another factor - the rate of natural population growth because of new births in different countries, in some countries it is very high, and in others - is extremely low.

Another important factor - the socio-economic conditions and the level of production in a particular country.For the same reasons, and the density varies considerably within countries - in cities and rural areas.As a rule, the population density in the cities than in the countryside, and the highest - in the capitals.
