Europe is, by convention, one of the world's seven continents. Comprising the westernmost peninsula of Eurasia, Europe is generally divided from Asia by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas, and the waterways connecting the Black and Aegean Seas.

Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south, and the Black Sea and connected waterways to the southeast. Yet the borders of Europe—a concept dating back to classical antiquity—are somewhat arbitrary, as the primarily physiographic term continent can incorporate cultural and political elements.

Europe is the world's second-smallest continent by surface area, covering about 10,180,000 square kilometres (3,930,000 sq mi) or 2% of the Earth's surface and about 6.8% of its land area. Of Europe's approximately 50 countries, Russia is by far the largest by both area and population, taking up 40% of the continent (although the country has territory in both Europe and Asia), while Vatican City is the smallest. Europe is the third-most populous continent after Asia and Africa, with a population of 733 million or about 11% of the world's population.

Europe has one of the best standards of living in the world and because of this many people are searching for a way to legally live there.

Economy
The economy of Europe comprises more than 731 million people in 48 different countries. Like other continents, the wealth of Europe's states varies, although the poorest are well above the poorest states of other continents in terms of GDP and living standards. The difference in wealth across Europe can be seen roughly in former Cold War divide, with some countries breaching the divide (Portugal, Slovenia and the Czech Republic). Whilst most European states have GDP per capita higher than the world's average and are very highly developed (Liechtenstein, Luxembourg, Monaco, Andorra, Norway, Sweden, the Netherlands, Switzerland), some European economies, despite their position over the world's average (except for Moldova and Turkey) in the Human Development Index (Armenia, Kosovo, Macedonia, Ukraine, Azerbaijan, Georgia, Bosnia and Herzegovina, Albania, Kazakhstan) are still catching up with European leading countries.

The European countries, with a long history of trade, a free market system, and a high level of development in the previous century are generally in the north and west of the continent. They tend to be wealthier and more stable than countries congregated in Europe's south and east, even though the gap is closing, especially in Central and Eastern Europe, partly due to higher growth rates, but partly also due to the equalizing effect provided by the European Union.

Europe in 2010 had a nominal GDP of $19.920 trillion (30.2% of World GDP). Europe's largest national economy is that of Germany, which ranks fourth globally in nominal GDP, and fifth in purchasing power parity (PPP) GDP; followed by France, ranking fifth globally in nominal GDP, followed by the United Kingdom, ranking sixth globally in nominal GDP, followed by Italy, which ranks seventh globally in nominal GDP, then by Russia ranking tenth globally in nominal GDP.
