The information requested falls within the responsibility of the UK Statistics Authority. I have asked the authority to reply.
Letter from Stephen Penneck, dated February 2010:
As Director General for the Office for National Statistics, I have been asked to reply to your recent question asking what the cancer mortality rate was in Feltham and Heston in (a) 1997 and (b) the latest period for which figures are available. (316686)
The table attached provides the age-standardised mortality rate, where cancer was the underlying cause of death, for Feltham and Heston parliamentary constituency in (a) 2001 (the earliest year available) and (b) 2007 (the latest year available).
Mortality rates for parliamentary constituencies which do not share boundaries exactly with a local authority can only be calculated from 2001 onwards.
|Table 1. Age-standardised mortality rate per 100,000 population,( 1, 2) where cancer was the underlying cause of death,( 3) Feltham and Heston parliamentary constituency( 4) , 2001 and 2007( 5)|
|Rate per 100,000 population|
|Rate||95 per cent. confidence interval|
|(1) Age-standardised mortality rates per 100,000 population, standardised to the European Standard Population. Age-standardised rates are used to allow comparison between populations which may contain different proportions of people of different ages. |
(2) Confidence intervals are a measure of the statistical precision of an estimate and show the range of uncertainty around the estimated figure. Calculations based on small numbers of events are often subject to random fluctuations. As a general rule, if the confidence interval around one figure overlaps with the interval around another, we cannot say with certainty that there is more than a chance difference between the two figures.
(4) Based on boundaries as of 2009.
(5) Figures are for deaths registered in each calendar year.
