Tourism’s contribution to GDP is another important indicator of T&T development since it relates to overall travel and tourism spending by domestic and foreign tourists, as well as spending by governments on travel and tourism related services like national parks and museums. Of all the major tourism monitoring organizations, WTCC provides the most comprehensive data on GDP from tourism, quantifying both its direct GDP effects as well as “total” impacts in order to provide a detailed picture of how T&T activity impacts the broader economy. The chart below shows direct and total contributed over an eight-year time series, with four years of historic data and a four year forward forecast data.
