Independent research - commissioned by a States body investigating the impact of low incomes - shows some claimants are living on 20 per cent less than the official 'poverty threshold.'
But the Social Security Minister says the real answer is getting people off benefits and into employment.
A study for the government Scrutiny panel investigating low incomes in the island has been analysing benefits rates over the past five years.
Latest figures show an income of less than £336 a week for a household, after housing costs, is considered Relative Low Income (RLI) or poverty.
The study found income support for single people meant they only reached 74% of RLI, 79% for a single parent with a child, and just 70% for a couple with no children.
The Social Security Department today accepted the figures though pointed out there were various ways of analysing the data which could produce different outcomes.
The study was presented to Social Security during their session giving evidence to the Scrutiny panel.
The weekend event coincides with International Pride Month and the 51st anniversary of the Stonewall riots.
The scheme has been backed by the island's Lieutenant-Governor, and is the first of its kind in the Channel Islands.
