Based on data available for direct and indirect expenditures and contributions, and employment and cruise versus land-based tourists, only three SIDS meet this requirement: Jamaica, Maldives and Mauritius. All three are well-researched destinations, where the tourism industry is monitored regularly by government ministries. Data are available from the national statistics office or tourism department; this is used here to emphasise examples of good practice. In some cases, tourism contributes more than 40 per cent of GDP, rising to 45.5 per cent in Aruba and 47.4 per cent in Maldives. These figures relate to total contribution to GDP and include direct and indirect contributions (Figure 1.1). Induced contributions are not included.
