The countries in the Caribbean region vary considerably in population, Gross Domestic Product (GDP) and per-capita GDP, social indicators, and production and export bases. They are all, however, constrained by the relatively small size of their economies and limited natural resources. Consequently, economies of scale are difficult to achieve. In addition, most countries’ outputs and/or exports rely heavily on one or two industries (e.g. tourism in the service sector, energy-related products in the manufacturing sector, and bananas or sugar in the agricultural sector). Despite the relatively high per-capita incomes for most countries, many have substantial social development problems, such as high poverty rates, income inequality, unemployment, underemployment, and susceptibility to external forces (including weather, economic fluctuations, and changes in global commodity prices). The Caribbean countries are highly dependent on international services and merchandise trade.
