Cruise industry statistics are very difficult to obtain. There has never been a passenger liner or cruise industry equivalent of the airlines IATA. The most dependable trade sources indicate that 16.9 million people embarked on a cruise in 2005. This is 9.5% up on 2004 and is at least double the maximum annual liner passengers in the Twentieth Century. The current annual gross tonnage of cruise ship deliveries is also double the peak liner deliveries.
It is thought that the 2005 world-wide cruise contribution to the economy was about $60 billion and about 600,000 jobs are created, directly and indirectly.
AIDA is of course part of the Carnival Group.
