This map shows dollars made through tourism. Worldwide US$573 billion was made from tourism in 2003. This money mainly goes to rich countries such as the United States, Spain, Italy and France. 10% of the world's territories take 72.7% of all tourist receipts.
Territories that are small and poor have low total tourist receipts when measured in US dollars; partly because a dollar buys more in a poor territory than it does in rich one. This helps the travel of people from rich places to poor places, but hinders a reverse flow.
