Age-standardised death rates calculated using the European Standard Population

Last updated: 2 August 2012

This section presents some ‘age-standardised’ death rates for Scotland as a whole, for 1979 onwards. They were calculated using the European Standard Population (ESP), in order to show trends in mortality from particular causes after taking account of changes in the distribution by age of the Scottish population. In addition, overall rates for people of all ages and for those aged under 75 are provided for NHS Boards and Local Authorities for 2006 onwards, together with figures for a few specific causes of death for NHS Boards only. They must be used with caution, because rates that are based on relatively small underlying numbers of deaths may be subject to relatively large percentage year-to-year fluctuations (more information about this is given below).

Because these rates are ‘age-standardised’, they are not directly comparable to the so-called ‘crude’ death rates that appear elsewhere on the Web site; because they were standardised using the ESP, they are not directly comparable to rates that were standardised using the distribution by age of the population of, say, Scotland or the UK in a particular year.

Age-standardised death rates for Scotland and administrative areas, calculated using the ESP

The tables below provide age-standardised death rates for Scotland, for each year from 1979 onwards, that were calculated using the ESP.

Rates for Scotland are given for all causes of death taken together and for several specific causes of death (cancer, diseases of the circulatory system, ischaemic/coronary heart disease, stroke/cerebrovascular disease, diseases of the respiratory system, chronic obstructive pulmonary disease, alcohol-related deaths, accidents, and probable suicides).

There are separate sets of rates for people of all ages and for people who were aged under 75. Most of the ‘under 75’ rates are markedly lower than the ‘all ages’ rates, because death rates from many causes are much lower for people aged under 75 than for older people.

Rates for NHS Boards and Local Authorities are given for all causes of death taken together. For NHS Boards, figures are also given for a few specific causes of death.

In most cases (but not for the figures for specific causes of death for NHS Board areas), separate age-standardised rates were produced for Males, Females and all Persons by applying the relevant age-specific death rates to the ESP's age-distribution. So, for example, the male age-standardised death rate is the weighted average of the male age-specific death rates for each age-group, using the ESP's age-distribution as the weight.

The age-standardised death rates for ‘Persons’ tend to differ slightly from the averages of the ‘Males’ and ‘Female’ age-standardised death rates. This is because differences in the size and distribution of the male and female populations often cause the overall death rate for a particular age-group to differ from the average of the male and female death rates for that age-group. As a result, an ESP-weighted average of the ‘Persons’ rates for each age-group may differ from the average of the ‘Males’ and ‘Females’ ESP-weighted averages of their age-specific rates.

There are also tables for Scotland giving age-and-sex-standardised death rates. These were produced simply by taking the average of the age-standardised ‘Males’ and ‘Females’ rates. As that gives equal weight to each sex, it is equivalent to using a standard population which has equal numbers of males and females, and identical distributions by age for males and for females.

The figures for administrative areas (in Tables 3 and 4) and for specific causes of death for NHS Board areas (in Tables 5 and 6), should be used with caution, particularly the figures for under 75s, or for areas which have relatively small populations, or for some specific causes of death. This is because, if the underlying numbers of deaths are relatively small, they and the calculated death rates may be affected by relatively large percentage year-to-year fluctuations. More information about this is available from the Fluctuations in, and possible unreliability of death statistics page on this website. NRS has no plans to produce more detailed age-standardised death rates (e.g. for particular types of cancer): being based on even smaller numbers of deaths, they could be subject to even larger percentage year-to-year fluctuations.

Tables

For Scotland, two tables are available: one for ‘all ages’; one for ‘under 75s’. Each spreadsheet contains four tables, which provide age-standardised death rates for all persons, for males and for females; and age-and-sex standardised death rates for all persons.

For NHS Boards and Local Authorities two tables are available: one for ‘all ages’; one for ‘under 75s’. Each spreadsheet provides age-standardised death rates for all persons, for males and for females.

For NHS Boards, two further tables are provided: one for ‘all ages’ and one for ‘under 75s’. Each spreadsheet provides age-standardised death rates from a few specific causes and the corresponding underlying numbers of deaths.

Further information for the rest of the UK can be found via the following links:

England & Wales - the annual ‘Mortality Statistics’ release, available via the Office for National Statistics website, includes death rates, for a number of causes of death, which have been age-standardised using the European Standard Population.

Northern Ireland - the numbers of deaths from various causes are given in the Annual Report of the Registrar General for Northern Ireland, which is available on the Northern Ireland Statistics and Research Agency (NISRA) website, together with some more detailed tables on various causes of death. However, those statistics do not include any death rates from particular causes which have been age-standardised using the European Standard Population.

Note: Figures for England & Wales and/or Northern Ireland may not always be on exactly the same basis as National Records of Scotland (NRS) figures: there can be differences in the coverage of what at first sight appear to be the same statistics.
