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.
Netherlands
The Netherlands had an estimated population of 17,093,000 as of January 2017. It is the most densely populated country in Europe, except for very small states like Monaco, Vatican City and San Marino. It is the 63rd most populous country in the world. Between 1900 and 1950, the country's population almost doubled from 5.1 to 10 million. From 1950 to 2000, the population further increased, to 15.9 million, though this represented a lower rate of population growth. The estimated growth rate is 0.44%.
