Data up to mid-2019 are for date of occurrence rather than date registered. Trends by date of registration are susceptible to having relatively higher spikes due to under-reporting on bank holidays and subsequent catching up of these death registrations. For this reason, we have smoothed an artificial peak and trough between 2019 week 52 to 2020 week 2 where an average over this period is instead shown. Population data up to mid-2019 based on Office for National Statistics estimates with subsequent figures extrapolated using more contemporaneous data on the trend in patients registered at a general practice.
