Key Insights

• 💁 Graunt's personal experiences with death in London and his understanding of the recording mechanisms informed his insights into cause of death.
• 🦗 The decline of the rickets descriptor as a cause of death may be more reflective of changes in fashion rather than a decrease in disease occurrence.
• 🤕 The teeth descriptor provides a more precise way of analyzing deaths in specific age groups, particularly in earlier mortality data where ages were not recorded.

Questions & Answers

Q: How does Graunt's personal experiences with death in London inform his understanding of mortality data?

Graunt's personal experiences with the deaths of his parents and daughter allowed him to understand how death was recorded in London and the mechanisms behind the Bills of Mortality. This firsthand knowledge enhanced his insights into the meaning of causes of death.

Q: Why did the cause of death descriptor for rickets decline despite the continued use of coal in London?

The decline in the rickets descriptor as a cause of death is likely due to it going out of fashion rather than a decrease in the actual occurrence of the disease. The use of coal in London increased during this period, which suggests that environmental factors may have contributed to the rise of rickets.

Q: What insights can be gained from studying the teeth descriptor as a cause of death?

The teeth descriptor primarily refers to the eruption of deciduous teeth in infants. It provides a more precise way of analyzing deaths in specific age bands. The consistent timing of teeth eruption allows researchers to estimate the ages of individuals in earlier mortality data where ages were not recorded.

Q: Did the use of old age as a cause of death descriptor change over time?

The use of old age as a descriptor for cause of death declined over time in most cases. However, there is variation between individual parishes, indicating different interpretations of what constitutes old age. Some individuals in the age group of 70 and above were instead assigned more specific causes of death like fever and dropsy.
