Letter from Karen Dunnell, dated
As National Statistician, I have been asked to reply to your recent Parliamentary Question asking what the life expectancy is of (a) males and (b) females in each of the 25 (i) most deprived electoral wards and (ii) least deprived wards; and how many on average of these years will be spent with a disability. (149945)
The attached table provides the period life expectancy at birth in the 25 (i) most deprived and (ii) least deprived wards in England and Wales, as a five-year average for 1999-2003 (the only period available). The figures are presented for (a) males, (b) females and (c) all persons, as some wards are too small for the calculation of life expectancies for males and females separately.
These figures are experimental statistics—that is, statistics which are in a testing or consultation phase and are not fully developed—and should therefore be treated with caution. Because life expectancies for wards can be based on very small numbers of deaths and small populations, they are subject to large variations even when averaged over five years, and extreme results may be due only to chance.
Based on these life expectancy figures, ONS will release experimental statistics on disability-free life expectancy at birth for wards on 23rd August 2007. These will provide a breakdown of the period life expectancy estimate for each ward into years spent without a disability (or disability-free) and years spent with a disability.
A recently published analysis showed that on average, males could expect to spend 18 out of 71 years (25 per cent.) of life with a disability in the most deprived twentieth of all wards in England and Wales grouped together, and 11 out of 79 years (14 per cent.) in the least deprived twentieth. Females could expect to spend 21 out of 78 years of life (27 per cent.) with a disability in the most deprived twentieth of wards, and 13 out of 82 years (16 per cent.) in the least deprived twentieth.(1)

|(1) Period life expectancy at birth is an estimate of the average number of years a newborn baby would survive if he or she experienced the area's age-specific mortality rates for that time period throughout his or her life. The figure reflects mortality among those living in the area in each time period, rather than mortality among those born in each area. It is not therefore the number of years a baby born in the area in each time period could actually expect to live, both because the death rates of the area are likely to change in the future and because many of those born in the area will live elsewhere for at least some part of their lives. |
(2) Wards for which life expectancy for one or both sexes could not be calculated due to small numbers are marked by '—'. Life expectancy for all persons combined is given for all wards.
(3) Deprivation was measured using the Carstairs deprivation score, which reflects levels of household overcrowding, male unemployment, low social class and car ownership.
(4) Five year averages, based on deaths registered in each year, and experimental ward population estimates based on the 2001 Census. The ward names and boundaries used are 2001 Census Standard Table wards.
(5) The presence of medical and care communal establishments; such as nursing homes and hospices, can artificially depress the average life expectancy of the ward in which they are located. To aid interpretation of the figures, this indicator shows the proportion of the population of each ward, aged 65 and over, who were resident in such establishments in 2001. For this purpose, all wards in England and Wales (not only the wards in these boroughs) were divided into six groups which are numbered from 0 to five:
'0' means that none of the over-65 population lived in medical and care communal establishments;
'1' means that the proportion of the over-65 population in such establishments was in the lowest fifth of all wards;
'5' means that the proportion of the over-65 population in such establishments was in the highest fifth of all wards.
