I understand that the Deputy's question refers to both persons in receipt of a State pension such as a Widow's or Widower's Pension as well as to persons in receipt of a pension arising from public sector employment. Either way, the information requested by the Deputy is not held by my Department.
The Deputy should be aware that Public Service pension entitlements may be carried from one Public Service employment to the next provided the employer is a member of the Public Service Transfer Network. Pensions are generally not payable until retirement age. Where they are being paid prior to retirement age, they will likely be subject to an actuarial reduction except in the case of the Incentivised Scheme of Early Retirement which was available to Civil and Public Servants in 2009.
