The Economy of Europe comprises more than 731 million people in 48 different countries. Like other continents, the wealth of Europe's states varies, although the poorest are well above the poorest states of other continents in terms of GDP and living standards. The difference in wealth across Europe can be seen roughly in former Cold War divide, with some countries breaching the divide (Greece, Portugal, Slovenia and the Czech Republic). Whilst most European states have GDP per capita higher than the world's average and are very highly developed (Liechtenstein, Luxembourg, Monaco, Andorra, Norway, Sweden, the Netherlands, Switzerland), some European economies, despite their position over the world's average (except for Moldova) in the Human Development Index (Albania, Armenia, Azerbaijan, Bosnia and Herzegovina, Georgia, Macedonia, Kazakhstan, Kosovo, Belarus, Ukraine) are still catching up with European leading countries.
