7.7.4 Deprivation and Life Expectancy at Birth – Hull and Comparators
Given that Hull is the 11 th most deprived local authority in England, it would be expected
that Hull‟s life expectancy would continue to remain much lower than many comparator
areas. However, life expectancy can be estimated by deprivation quintile for comparator
areas, and these can then be compared with Hull, to assess whether the most deprived
people in Hull, for example, have seen better or worse improvements in life expectancy
than the most deprived people in comparator areas. This section contains the results of
some analyses that did just this, using national mortality data as well as population
estimates at lower layer super out area (LLSOA) for the entire country. This work was
possible due to the assistance of the Yorkshire and Humber Public Health Observatory,
who hold a copy of the national mortality file (Public Health Mortality Files for all
geographical areas combined) and have commissioned Office for National Statistics
(ONS) to produce the LLSOA population estimates. At the time the analyses were
undertaken, the most recent period for which data were available was 2008. It should
be noted that, because the LLSOA population estimates are derived from resident
population estimates, which tend to be different to the GP registered populations used
locally, the life expectancy estimates produced will not be the same as those produced
using local data. It should also be noted that, in order to make comparisons with other
areas, the analyses were performed using national quintiles of IMD 2007, which means
that there were no Hull life expectancy estimates for the least deprived quintile, as none
of the LLSOAs in Hull lie within the least deprived fifth of LLSOAs nationally (see
section 6.9.1 on page 131). Comparisons were made between Hull and North East
Lincolnshire, as well as the averages for the 10 comparator PCTs (see section 3.3.3.1
on page 44), Spearhead PCTs, the 20 most deprived PCTs in England, the Industrial
Hinterlands group of local authorities, the Yorkshire and Humber region and England.
Figure 54 and Figure 55 show the life expectancy at birth 2006-2008 for men and
women respectively living in areas that lie within the most deprived 20% of areas
nationally. Some 53% of Hull residents live in areas in the most deprived 20% of areas
nationally. Men in Hull living in the most deprived 20% of areas nationally had lower life
expectancy than each of the comparators, statistically significantly lower than the
average for the 20 most deprived PCTs and England, based on non-overlapping
confidence intervals. The difference in life expectancy between Hull and England was
much lower among men living in the most deprived fifth of areas nationally (0.9 years
lower in Hull) than among all men combined (2.4 years lower in Hull). Life expectancy at
birth amongst women in Hull living in areas in the most deprived 20% of areas nationally
was also lower than each comparator area shown, and was statistically significantly
lower than the average for women in comparator PCTs, Spearhead PCTs, the 20 most
deprived PCTs, the Yorkshire and Humber region and England. Again, the differences
between Hull and England were lower for women living in the most deprived fifth of
areas nationally (1.4 years lower in Hull) than among all women combined (2.5 years
lower in Hull). The underlying data are given in Table 74 and Table 75.
