Some interesting statistics. It's a compilation from statistics you can find here :
Banco Central de la República Dominicana
Some remarks :
The 2007 estimation is based upon figures from the first three months and assuming that in 2006, the first three months represented 29.55 percent of the total...
The big decrease in German tourists occured in 2001/2002 ! Why ???
Is it possible that Canadian tourists will double this year ? and surpass those coming from USA ??? Or did I make a mistake somewhere ???
My opinion : if those figures are correct, some differences between origin countries are mainly explainable by the commercial politic of major Tour Operators ! Not possible otherwise !!
