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.
Transport in Europe
Transport in Europe provides for the movement needs of over 700 million people and associated freight. The political geography of Europe divides the continent into over 50 sovereign states and territories. This fragmentation, along with increased movement of people since the industrial revolution, has led to a high level of cooperation between European countries in developing and maintaining transport networks. Supranational and intergovernmental organisations such as the European Union (EU), Council of Europe and the Organization for Security and Co-operation in Europe have led to the development of international standards and agreements that allow people and freight to cross the borders of Europe, largely with unique levels of freedom and ease.
