The Solomon Islands in numbers
The Solomon Islands has a population of 838,645 (2025) and a GDP of 14.6 billion Solomon Islands dollars (about 1.75 billion US dollars) in 2025.
Paying everyone 700 Solomon Islands dollars a month would cost 7.04 billion Solomon Islands dollars a year (about 846 million US dollars), or 48.4% of GDP. That equals 167% of central government expense (2022), 190% of its revenue (2024), and 208% of its tax revenue (2024).
Children only (under 18: 359,294) would cost 3.02 billion Solomon Islands dollars a year (20.7% of GDP); adults only (18 and over: 479,351), 4.03 billion Solomon Islands dollars (27.6%).
Default amount: 700 Solomon Islands dollars a month is the World Bank's international poverty line of $3.00 a day (2021 PPP), converted into Solomon Islands 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).
