The travel and tourism sector grew 3.9 percent to $8.8 trillion in 2018, accounting for 10.5 percent of global gross domestic product, and outpacing global GDP growth of 3.2 percent, according to the World Travel & Tourism Council.

Based on data from 185 countries, the group forecasts steady growth of 4 percent this year, given continued demand from China, the second largest travel and tourism market behind the United States, and other countries in Asia.
