Question to the Department for Work and Pensions:

To ask His Majesty's Government whether the Department for Work and Pension's long-term model of pensioner incomes (Pensim3) is open access, including information on the underlying assumptions and formulae.

Pensim3’s baseline data contains information from real individuals and is subject to data protection controls.

Pensim3’s economic and demographic assumptions align with OBR’s Fiscal Risks and Sustainability Report and ONS’s population projections. Other assumptions are outlined in the relevant published results (e.g. future pensioner incomes: https://www.gov.uk/government/statistics/analysis-of-future-pension-incomes/analysis-of-future-pension-incomes).
