Question to the Department for Work and Pensions:

To ask the Secretary of State for Work and Pensions, if he will make a comparative assessment of the number and proportion of women affected by the increase in state pension age for women born in the 1950s who died before receiving their state pension (a) between1948 and 31 December 2015 and (b) since 31 December 2015; and whether there are statistically significant differences in those mortality rates.

We have not undertaken the requested analysis and therefore do not hold the information you have requested.
