The information requested falls within the responsibility of the UK Statistics Authority. I have asked the Authority to reply.
Letter from Stephen Penneck, dated 16 March 2010:
As Director General for the Office for National Statistics, I have been asked to reply to your recent Parliamentary Question asking pursuant to the Answer of 22 February 2010, Official Report, column 159W, on death: cancer, for what reasons age-standardised mortality rates for 2008 are (a) unavailable by parliamentary constituency and (b) available for primary care trusts; when she expects the 2008 data broken down by parliamentary constituency to be made available. (322228)
Calculation of mortality rates requires both the number of deaths and an estimate of the population for the same area and time period. Mortality rates for (a) parliamentary constituencies could not be calculated for 2008 as mid-year population estimates for parliamentary constituencies in 2008 were not yet available. The equivalent rates for (b) primary care organisations could be calculated as ONS published mid-year population estimates for primary care organisations in October 2009. The 2008 mid-year population estimates for parliamentary constituencies are due to be published in July/August 2010.
