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.
England
With over 53 million inhabitants, England is by far the most populous country of the United Kingdom, accounting for 84% of the combined total. England taken as a unit and measured against international states has the fourth largest population in the European Union and would be the 25th largest country by population in the world. With a density of 424 people per square kilometre, it would be the second most densely populated country in the European Union after Malta.
