Subject Keywords: Five year age-standardised mortality data and standardised mortality ratios (SMRs)
Catalogue: Data

Type: Table
Region: Republic of Ireland
Description:

Five year age-standardised mortality rates by county, sex and cause are presented in this table. These allow comparison of mortality rates between populations of different age composition, and also of mortality rates over time. The age-standardised rate for an area is the number of deaths (per 100,000) that would occur if that area had the same age structure as the WHO European Standard Population and the local age-specific rates for that area applied. Confidence intervals for these rates are also presented.

The data cover the years from 1980 to 2012. For 2012, year of registration data are used; for all previous years, statistics are based on year of occurrence. A total of 74 causes of death categories are reported. These are ordered according to the Eurostat 65 Cause of Death shortlist, along with 9 additional national categories.

The classification system used for data up to and including 2006 is ICD9. From 2007, ICD10 is used. Caution should be exercised in comparing data up to 2006 with data from 2007 onwards. Standardised Mortality Ratios (SMRs) are also included. SMRs express the difference between the observed deaths in each county compared to the expected deaths if the age-specific rates of the national population applied. It is presented as a ratio. A ratio more than 100 indicates that county experienced higher mortality than would be expected. A ratio lower than 100 indicates that county experienced lower mortality than would be expected. Confidence intervals for these rates are also presented.

NOTES:

1. All statistics in this table are based on a 5 year moving average. Population used in the calculations is the mid-year population of each 5 year period.

2. Confidence intervals based on less than 50 cases should be viewed with caution as larger, less exact confidence intervals are produced. Rates showing wide confidence intervals should be viewed with caution.

3. SMRs based on a small number of cases should be viewed with caution.

4. The SMRs presented cannot be used to compare counties with each other, as each county’s population structure weights the age-specific mortality rates differently.
