The London Bills of Mortality were originally and primarily focused on deaths from plague, however they very quickly expanded to include other causes of death as well. From accidents and drownings to measles and smallpox, the printed bills included citywide summary statistics—rather than parish-by-parish breakdowns—for each week. While we can therefore learn a fair amount about causes of death throughout the city, very little information can be gleaned from the sixteenth- and seventeenth-century bills about the age at which people died.
