The top five countries in terms of the number of people living in each country are Germany, the UK, France, Japan and Italy, according to new figures released by the International Monetary Fund.
The top five are also the countries with the highest unemployment rates in 2018.
Germany is the biggest offender with 4.1 percent of the population in employment, followed by France with 3.9 percent and Japan with 3 percent.
The top three countries in Europe are Italy with 1.4 percent and Spain with 1 percent.
Italy has the most young people in the world, with about 2.3 million.
This is in addition to the 2.2 million that are under 25, or 16.9 million people, according the OECD.
Italy is also the third most populous country in Europe.
This means that it has a higher population than the United States and Russia combined.
Russia has the third largest population in Europe, at about 1.9 billion, followed closely by Germany at 1.7 billion.
Italy was the first European country to become a member of the European Union.
It joined in June of this year, but it has been slow to become part of the bloc.
It has been unable to pass a bill that would make the country part of its economic powerhouse, which includes Europe.
