As per business research, the tourist arrivals in the USA are expected to top eighty million by the year 2018 compared to less than seventy million for 2013. Rising affluence in Asia and South America have been quoted as significant reasons. This provides great opportunity to develop more and more tourism jobs in the USA. Certain major global events affect the tourists numbers as hallmark events like the Football World Cup in 2014 in Brazil, London Olympics in 2012 or the 2011 Cricket World Cup in India boost numbers. On the other hand, outbreak of the feared Ebola disease in west Africa disrupted tourism in much of that region. Medical tourism is one field which is growing at electric pace.
