Europe
In 2017, the population of Europe was estimated to be 742 million according to , which is slightly more than one-ninth of the world's population. This number includes Asian Russia (Siberia, about 36 million people) but excludes the European part of Turkey, Cyprus and the Transcaucasian countries.
A century ago, Europe had nearly a quarter of the world's population. The population of Europe has grown in the past century, but in other areas of the world (in particular Africa and Asia) the population has grown far more quickly. Among the continents, Europe has a relatively high population density, second only to Asia. Most of Europe is in a mode of Sub-replacement fertility, which means that each new(-born) generation is being less populous than the older.
The most densely populated country in Europe (and in the world) is the microstate of Monaco.
European mouflon
In the introduced populations of Central Europe it is estimated that there are over 60,000 mouflon (in 2005 there were 90,000), the largest population being in the Czech Republic (17,500). The population in Germany was around 15,600 animals in 2010 (c. 20,600 in 2005) living in about 120 groups. In Hungary there are around 10,600 and in Austria about 7,500 mouflon (no herds in Vorarlberg). In the early 1980s, mouflon migrated from France to the Swiss canton of Valais, where there are now two colonies with a population of around 200 animals. The IUCN considers the European mouflon to be 'at risk'.
