The Personal Independence Payments (PIP) benefit system has been criticised strongly since it was introduced but despite calls for improvements, the latest figures show that over half of new claimants have been rejected since the system came in.
The data, which was published by the Department for Communities and focuses on Northern Ireland, also shows that a quarter of people in the region wanting to move from Disability Living Allowance (DLA) to PIP have been unsuccessful.
The figures show that around 77,000 people out of the 135,400 registered for the PIP scheme in Northern Ireland are receiving payments.
PIP has been heavily criticised in recent months after a series of complaints from politicians and claimants who say that the assessment process is unfair and people in severe need of funding are deemed ineligible.
The Government promised to reform the system but the contracted firms responsible for the assessments managed to regain their tenders recently.
In January, the Government has said that all 1.6m claims will be reviewed after months of criticism and pressure.
