How many countries are there in the world? It is very interesting and debatable question. The list of the countries of the world includes 194 independent states. But there exist also besides the independent states the disputed and unrecognised territories, which are regarded by some people as the self sufficient countries, while other people believe that those or other territories are the constituent parts of some country.

Each country has its own individuality. There exist the wealthy countries, and there exist those ones, where the most of the population lives below the poverty level. There exist the developed countries, the developing ones, and also the countries of the third world, many of which are struggling for the survival. There exist the multinational states, but at the same time there also exist the countries with the small population, where the most of the population belongs to the same race, religion, and speaks the same language. Every state has its own history, customs and traditions, which change in appearance during the development of the country.

The most wealthy country of the world is Quatar, with the population of only 1.5 million. The per capita income, which is 121700$, is taken as the basis for the calculation. And the most poor country of the world is Zambia, where the 86% of the whole population lives below the poverty level. Russia is accounted as the largest country in the world, one may notice it by just looking at the map, without starting any calculations.

And the greatest density of the population is certainly in China, there is living there about the fifth part of the population of the whole planet. At the same time, the combined population of the countries of the world is about seven billions people.

During the last two decades, there appeared on the political map of the world more than dozen of the countries. Certain countries disintegrate, and certain ones are moving to the integration and unification. There happen wars, coups, because of which the countries change their names or cease to exist altogether. The map of the modern world changes continuously.

Today, they identify 23 regions of the world: North Europe, Eastern Europe, Western Europe, South Europe, Russia (as the separate region), Western Asia, Central and South Asia, Eastern Asia, North Africa, Western Africa, Central and Eastern Africa, North America, Central America, Andes America, Tropical South America, Australia and Oceania. Each of these regions may be characterized, and they would not be similar one to another, tempting by their diversity and peculiarities.
