Pensionable ages for men and women

Between 2010 and 2020, state pension age will change from 65 years for men and 60 years for women, to 65 years for both sexes. Any woman born before 6th April 1950 will attain pensionable age when she reaches the age of 60. Any woman born after 5th April 1955 will attain pensionable age when she reaches the age of 65.
For women born between these dates, the date that pensionable age will be attained can be found in Table 1.

Calculation of female population of working age and population of pensionable age for national population projections

The projected populations of working age and pensionable age are given in the appropriate results file (Microsoft Excel document 122kb).

From 2004 to 2009, all women aged 60 to 64 are of pensionable age. From 2020 onwards, all women aged 60 to 64 are of working age. From 2010 to 2019, the number of women aged 60 to 64 who are of pensionable age is calculated using Table 2.

Table 2

Proportion of women aged 60 to 64 taken to be of pensionable age, 2010 to 2019
	2010	2011	2012	2013	2014	2015	2016	2017	2018	2019
60	309/365	128/365	0	0	0	0	0	0	0	0
61	1	1	309/365	128/366	0	0	0	0	0	0
62	1	1	1	1	310/366	128/365	0	0	0	0
63	1	1	1	1	1	1	309/365	128/365	0	0
64	1	1	1	1	1	1	1	1	309/365	128/365

So, taking the projected number of women aged 60 to 64 in the UK at mid-2015 as an example:

From Table 1 above, we see that all women born on or before the 5th November 1952 will be of pensionable age at mid-2015. This will include all women aged 63 or 64 at mid-2015, plus some women aged 62. Of those aged 62 at mid-2015, those born between 1st July 1952 and 5th November 1952 will be of pensionable age, but those born between 6th November 1952 and 30th June 1953 will be of working age. Making the simplifying assumption that there is an even distribution of birthdays for women at these ages, we have taken 128/365 of women aged 62 at mid-2015 to be of pensionable age and the remaining 237/365 to be of working age.
