The Channel Islands in numbers

The Channel Islands has a population of 168,466 (2025) and a GDP of 10.1 billion British pounds (about 12.5 billion US dollars) in 2023.

Paying everyone 73 British pounds a month would cost 148 million British pounds a year (about 183 million US dollars), or 1.5% of GDP. The World Bank has no recent central government expense or tax figures for the Channel Islands, so only GDP is compared.

Children only (under 18: 28,967) would cost 25.4 million British pounds a year (0.25% of GDP); adults only (18 and over: 139,499), 122 million British pounds (1.2%).

Default amount: 73 British pounds a month is the World Bank's international poverty line of $3.00 a day, converted into British pounds at the exchange rate implied by the World Bank's GDP in local currency and in US dollars (2023), because there is no recent PPP conversion factor, 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).
