Question to the Department for Work and Pensions:

To ask Her Majesty's Government what was the proportion of the UK population over state pension age in 1990; and what is the projected figure for 2050.

In 1990, State Pension age was 60 years of age for females and 65 years for males. Based upon Office for National Statistics (ONS) mid-year population estimates, the proportion of the total UK population over State Pension age in 1990 was 18.4 per cent.

In 2050, State Pension age is legislated to be 68 years of age for both males and females. Based upon ONS 2018 mid-year population projections, the most up-to-date ONS population projections available, the proportion of the total UK population over State Pension age in 2050 is estimated to be 21.4 per cent.

Percentages have been rounded to 1 decimal place.

These figures have been calculated using data available on the ONS website: www.ons.gov.uk
