Grenada relies on tourism and revenue generated by St. George’s University - a private university offering degrees in medicine, veterinary medicine, public health, the health sciences, nursing, arts and sciences, and business - as its main source of foreign exchange. In the past two years the country expanded its sources of revenue, including from selling passports under its citizenship by investment program. These projects produced a resurgence in the construction and manufacturing sectors of the economy.
In 2017, Grenada experienced its fifth consecutive year of growth and the government successfully marked the completion of its five-year structural adjustment program that included among other things austerity measures, increased tax revenue and debt restructuring. Public debt-to-GDP was reduced from 100% of GDP in 2013 to 71.8% in 2017.
