PARLIAMENTARY WRITTEN QUESTION
State Retirement Pensions: Females (19 December 2017)

Women born between 6 April 1950 and 5 April 1953 were affected by State Pension age equalisation under the Pensions Act 1995. The Pensions Act 2011 accelerated the equalisation of State Pension age, and included transitional arrangements limiting State Pension age delays, affecting women born between 6 April 1953 and 5 December 1953. It also brought forward the increase in State Pension age from 65 to 66 which affected women born between 6 December 1953 and 5 April 1960.

Information on the numbers affected by parliamentary constituency is not held by the Department for Work and Pensions. However, the most recent population breakdowns for Wales and its parliamentary constituencies by age can be found here:
