Both organisations have 28 members, though they are not the exact same 28 countries.
Among other things: part of Europe; part of the European Union; part of NATO; part of the World.
North Atlantic Treaty Organization (NATO) and European Union (EU)
There were 25 countries in the European Union in 2006.
People do not join the European Union. Countries do. It is an organisation of countries, not of people. As a result of countries joining, people are living in countries that are in the European Union and can be called its citizens.
I will be visiting nine European countries in the space of four days. How many countries belong to NATO?
Europe is a continent with over 50 countries. The European Union is an organisation. As of 2013, 28 of the countries in Europe are members of the European Union. Many countries in Europe are not members.
Some people may think it is a region because it has countries in it and all those countries are in the same part of the world, and some people think the European Union is the same thing as Europe. The European Union is not a region though. It is an organisation that has countries as members. There are many such organisations around the world. The UN is not a region, NATO is not a region, the Commonwealth is not a region, and neither is the European Union. Europe is a continent and you could say it is a region. A large amount of the countries in Europe are not in the European Union.
The UN (United Nations) is a international organization of every recognized state, created to keep the peace between nations and help create international law and cooperation. NATO (North Atlantic Treaty Organization) is a military and political alliance of the United States, Canada and most of Europe, created back in the Cold War to counter Soviet and Communist power. It now consists of 28 nations. The countries in the NATO are in a political and military alliance towards self defense and maintaining peace so to build trust and prevent conflict, and keep the safety of the countries. NATO is also committed to the principle of collective defense, which is that an attack against one or several members is an attack against all.

The USA is a country. The European Union is an organisation. It has 27 member countries, which are all independent countries. So there are many differences between the USA and the European Union.
The European Union are both international organisations. Some countries are members of both organisations, though some are members of one but not the other. That is the only connection. Apart from sharing some members, they are completely different organisations in many different ways.
The population of the European Union is roughly half a billion.
