Tourism is increasingly becoming a major industry for many countries. International travel is growing in many emerging countries due to rising income levels and easier access to travel abroad. Globally, tourism spending totaled US$1.03 trillion in  2011 for increase of 3.8% over 2010 levels. The top three countries in international tourist arrivals ranked in order are France, USA and China in 2011. 79.5 tourists visited France last year which is more than its population of about 65.0 million.  In terms of revenues, the U.S. topped the list with international tourist receipts of just over $116.0 billion.
