Age-standardised mortality rates per 100,000 population, standardised to the 2013 European Standard Population. Monthly rates in this bulletin are adjusted to allow for comparisons with annual rates. For more information, see the [Measuring the data section](https://www.ons.gov.uk/peoplepopulationandcommunity/birthsdeathsandmarriages/deaths/bulletins/monthlymortalityanalysisenglandandwales/may2022#measuring-the-data). 2. Figures for 2021 and 2022 are based on provisional mortality data and projected populations. 3. COVID-19 includes only deaths where COVID-19 was the underlying cause of death. 4. Figures exclude deaths of non-residents. 5. The five-year average has been provided for 2016 to 2019 and 2021 because of the impact of the coronavirus pandemic on deaths registered in 2020. This provides an up to date comparison (rather than 2015 to 2019) of the number of deaths expected per month in a usual (non-coronavirus pandemic) year. Where a five-year average cannot be provided, it is denoted as ""[z]"" in the data downloads. 6. Leading causes are ranked based on number of deaths, not age-standardised mortality rates."
