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.
Geography of Europe
Figures for the population of Europe vary according to which definition of European boundaries is used. The population within the standard physical geographical boundaries was 701 million in 2005 according to the United Nations. In 2000 the population was 857 million, using a definition which includes the whole of the transcontinental countries of Russia and Turkey. Population growth is comparatively slow, and median age comparatively high in relation to the world's other continents.
