What this means

From August 2021 to July 2022, Norfolk's winter mortality index was 10.4%. This compares deaths in December to March with the average of the adjacent non-winter periods; it is not a count of deaths caused by cold weather.

Source denominator: 3,550 deaths, the average of the adjacent non-winter four-month periods. This is not a population denominator.

Fingertips comparison: Similar England.

Caveats

  • Old data: this is the latest local series, and publication of the indicator has been paused.
  • The index is not age-standardised and is partly influenced by the age profile of the population.
  • It compares seasons; it does not identify which deaths were caused by cold weather.
  • 95% confidence interval: 6.2% to 14.8%.
  • Derived from the published point estimates for 151 upper-tier authorities with data. Exact ties share a rank; 3 areas have this published value. Overlapping confidence intervals mean nearby ranks may not be meaningfully different.
  • A lower index means a smaller seasonal increase in mortality, not necessarily lower mortality overall.
