Mortality is the number of deaths, in general or specific to a cause, in a particular population. It is specifically used as a rate to measure the number of deaths on a large scale (in this case per 100,000), which is calculated to allow comparison between different population sizes and demographics.

Premature Mortality

Premature mortality is a good high-level indicator of the overall health of a population, being correlated with many other measures of population health: there are significant differences between the premature death rates in different areas, reflecting a wide range of underlying differences between these populations.

Bolton's mortality rate from all causes, all ages, by gender

The latest release of data is for 2021-23, which gives Bolton an overall under 75 mortality rate of 441 per 100,000 population; this rate is lower for women (330 per 100k) than men (552 per 100k) residing in Bolton.

Bolton is as expected when comparing them to the North West region for the majority of under 75 premature mortality indicators; being significantly worse than the national benchmark for cardiovascular diseases, heart disease, cancer, liver disease and respiratory disease.

Bolton has the 24th highest (out of 151 local authorities) rate for premature mortality of all causes. Blackpool is the worst (1) followed by Manchester, Kingston upon Hull and Liverpool.

Preventable Mortality

A death is preventable if, in the light of understanding of the determinants of health at the time of death, all or most deaths from that cause (subject to age limits if appropriate) could be avoided by public health interventions in the broadest sense.

Similarly to premature mortality indicators, Bolton sits around mid-table, when comparing them to the rest of the North West for the majority of preventable mortality indicators, larger differences are only seen when broken down by gender.
