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.
Immigration by country
Some EU member states are currently receiving large-scale immigration: for instance Spain, where the economy has created more than half of all new jobs in the EU over the past five years. The EU, in 2005, had an overall net gain from international migration of +1.8 million people. This accounts for almost 85% of Europe's total population growth in 2005. In 2004, total 140,033 people immigrated to France. Of them, 90,250 were from Africa and 13,710 from Europe. In 2005, immigration fell slightly to 135,890. British emigration towards Southern Europe is of special relevance. Citizens from the European Union make up a growing proportion of immigrants in Spain. They mainly come from countries like the UK and Germany, but the British case is of special interest due to its magnitude. The British authorities estimate that the British population in Spain at 700,000.
