Estimated excess mortality for specific underlying causes of death by age group in England during three heatwaves in 2020. Bold values indicate all-cause excess mortality estimates considered to be statistically significant (above 3SD), with values within the brackets the 95% Confidence intervals. Heatwave1 (H1) occurred from 23 to 27 June affecting EM, WM, EoE, LON, SE, and SW; Heatwave2 (H2) occurred from 30 July to 1 August. All regions affected; Heatwave3 (H3) occurred from 5 to 15 August affecting EoE, LON, and SE.
