Mortality rates show the number of people who die relative to the size and age of the population at any one time, giving a general measure of the health of that population.
A variant of this is the subset of deaths considered to be ‘amenable to healthcare’. This refers to premature deaths (under age 75) for diseases where it is believed that effective and timely healthcare can reduce the chances of somebody dying.
In both cases, it has been recognised for a long time that people who live in more affluent areas, or more affluent social groups, have better health and this can be seen in terms of lower mortality rates among these populations.
Data are based on latest revisions of Office for National Statistics (ONS) population estimates for the respective years. Numerators are the total number of deaths in specific age groups, or number of deaths judged to be amenable to healthcare, as appropriate HSCIC 2013. Amenability to healthcare is based on the original underlying cause of death, and being aged under 75. Denominators are 2011 census-based mid-year population estimates for the respective calendar years. Mortality amenable to healthcare only considers populations aged 0 to 74.
