By 1996, these measures had increased the share of the private sector in total investment to more than 50 per cent. The tertiary sector has generated most of the economic growth experienced since 1990, essentially due to the strong performance of tourism, which has also fuelled the growth of transport, construction, banking and insurance. This has allowed the achievement of free, universal and compulsory schooling for at least six years. This led to employment creation and high GDP growth rates, resulting in tourism overtaking fisheries as the largest sector in 1985 and contributing more than two thirds of GDP by 2013. The growth of tourism has been driven in part by the foreign private sector, with the support of government incentives and strategies, and facilitated by the absence of taxes and low rents.
