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.
Youth mentoring
The Romani population is about 1.9% of the total population in Hungary, according to the 2001 census. There are 12 Million Romani across Europe, and they account for one of Europe's most vulnerable populations. Within the Romani population, there is a lack of education amongst youth accompanied by large numbers of illiteracy. Because of this trend, there was the creation of The Roma Mentor Project, which provides successful Romani adults to be role models of Romani youth. The program started in 2006, and by 2011, it spread to four other European countries with 1,400 participants. The program matches professionals in many different fields, such as government officials, professors, musicians, and media figures. These adults meets with groups of youth for two to three hours, twice a month, to influence their future decisions on education and career development. Already the program has found a shift in attitudes toward education and improvement in grades.
