Europe is geologically and geographically a peninsula or subcontinent, forming the westernmost part of Eurasia. It is conventionally considered a continent, which, in this case, is more of a cultural distinction than a geographic one. It is bounded to the north by the Arctic Ocean, to the west by the Atlantic Ocean, to the south by the Mediterranean Sea, and to the east its boundary is culturally determined and unclear. However, the Ural mountains are considered by some to be a geographical and tectonic landmark separating Europe and Asia.
World map showing Europe (geographically)When considered a continent, Europe is the world's second-smallest continent in terms of area, with an area of 10,600,000 km² (4,140,625 square miles), making it larger than Australia only. In terms of population, it is the third-largest continent (Asia and Africa are larger). The population of Europe is roughly 700,000,000: about 11% of the world's population.

Geography of Europe
Geographically Europe is a part of the larger landmass known as Eurasia. The continent begins at the Ural Mountains in Russia, which define Europe's eastern boundary with Asia. The southeast boundary with Asia isn't universally defined. Either the Ural or Emba rivers can serve as possible boundaries. The boundary continues with the Caspian Sea, and either the Kuma and Manych rivers or the Caucasus mountains as possibilities, and on to the Black Sea; the Bosporus, the Sea of Marmara, and the Dardanelles conclude the Asian boundary. The Mediterranean Sea to the south separates Europe from Africa. The western boundary is the Atlantic Ocean, but Iceland, much farther away than the nearest points of Africa and Asia, is also included in Europe. There is ongoing debate on where the geographical centre of Europe is.
The idea of the European continent is not held across all cultures. Some non-European geographical texts refer to the continent of Eurasia, or to the European peninsula, given that Europe is not surrounded by sea and is, in any case, much more a cultural than a geographically definable area. In the past concepts such as Christendom were deemed more important.
In another usage, Europe is increasingly being used as a short-form for the European Union (EU) and its members, currently consisting of 25 member states. A number of other European countries are negotiating for membership, and several more are expected to begin negotiations in the future (see Enlargement of the European Union).

Population
Europe is a continent populated from old and intensely transformed. They have a developed capitalist economy, which allows him to benefit from high densities of population and to be a rich country. But the population unequally is distributed. We can be found with some of the higher densities of population of the world and authentic demographic emptinesses.
In central Europe the 100 are surpassed h/km2, and even the 300 h/km2; the next countries are between 50 h/km2 and the 100 h/km2; and in the the 25 Nordics they do not surpass h/km2, also unequally distributed since in the north the 2 are not surpassed h/km2. The emigration has been one of the remarkable characteristics of the European population.
When the population began to grow over the economic development, an exit to the lack of opportunities went the emigration to the colonies and the new countries, America and Australia. Million of European emigrated then. Also the emigration from the field to the city in search of better opportunities was a constant to gain the life. The field became depopulated. The new industry needed the force of work concentrated and broken ties with the field. The third migratory cycle took place after World War II. The countries in which work force exceeded, countries of the south, like Spain, left million emigrants for the central Europe, that was been in war.
