St. Lucia in numbers
St. Lucia has a population of 180,149 (2025) and a GDP of 7.17 billion East Caribbean dollars (about 2.66 billion US dollars) in 2025.
Paying everyone 150 East Caribbean dollars a month would cost 324 million East Caribbean dollars a year (about 120 million US dollars), or 4.5% of GDP. The World Bank has no recent central government expense or tax figures for St. Lucia, so only GDP is compared.
Children only (under 18: 38,424) would cost 69.2 million East Caribbean dollars a year (0.96% of GDP); adults only (18 and over: 141,725), 255 million East Caribbean dollars (3.6%).
Default amount: 150 East Caribbean dollars a month is the World Bank's international poverty line of $3.00 a day (2021 PPP), converted into East Caribbean dollars with the World Bank's PPP conversion factor for household consumption (2025) and rounded to two significant figures. It is a reference point, not a policy proposal; change it above.
How to read this
This is the gross cost: the total paid out. The real net cost depends on which taxes fund it, which benefits or tax breaks it replaces and whether the payment is taxed. The population, budget and GDP figures are not all from the same year (see the sources).
