Figures in a report disclosed under the Freedom of Information Law show that the cost of keeping the States going per Islander in Jersey is £9,307, compared to £5,907 in Guernsey.
The difference – around £340 million per year in terms of public spending – is part of the executive summary of former States cost-cutting consultant Kevin Keen’s report.
His report puts the key difference as the cost of Social Security, which is twice as expensive to run in Jersey as it is in Guernsey.
The differences in spending, adjusted for Jersey’s higher population, are £93 million on Social Security, £26 million on health and £19 million on Transport and Technical Services.
