Summary

This presentation from the Université Bretagne Sud, part of a colloquium, focuses on identifying mortality crises in the region of Martigues and Saint-Chamas in Provence during the second half of the 18th century. The researchers use parish registers (baptisms, marriages, burials) from two communities, provided by Généanette, to analyze annual burial trends and deviations from the long-term trend. They find no major crisis like the plague, but several epidemic episodes, notably in 1760. Detailed analysis of the 1760 peak in Saint-Chamas reveals a summer-autumn excess mortality, particularly among infants and children under 10, with a doubling of deaths in September. The age distribution shows high child mortality, with 8 out of 10 deaths among children under 10. The researchers hypothesize childhood epidemics such as smallpox, measles, or whooping cough, as well as intestinal diseases, supported by contemporary medical topographies and hospital admission data. They also note the impact of the Seven Years’ War and economic difficulties. The presentation concludes by acknowledging the difficulty of linking land and sea mortality, and mentions a recent publication on epidemic import-export in ports. The study is preliminary, with hypotheses to be further tested.

Critical Evaluation

Value of the Information & Strength of the Argument

The value of the information lies in the use of primary sources and quantitative methods to identify mortality crises in a specific region and period. The argumentation is solid, based on demographic calculations and comparisons with contemporary medical observations. The researchers are careful to distinguish between different types of crises (subsistence vs. epidemic) and to consider multiple causes. However, the study is preliminary, and some conclusions are speculative, such as the specific epidemic responsible for the 1760 peak.

Scientific Rigor, Source Quality, Title Accuracy

The scientific rigor is high: the study uses parish registers, a primary source, and applies demographic methods to measure mortality deviations. The sources are clearly described, and the researchers acknowledge limitations. The title is appropriate, though the ‘at sea’ part is not fully addressed. The presentation is well-structured, with clear graphs and tables. No comments were provided, so no public trends can be analyzed.

The title accurately reflects the content, though the 'at sea' part is underdeveloped.

Quality & Reliability

7/10

The presentation is based on primary sources (parish registers) and follows rigorous demographic methods, but it is a preliminary study with hypotheses not fully verified.

Contribution & Novelties

This study contributes to the demographic history of Provence by providing a detailed analysis of mortality crises in two communities, using parish registers and quantitative methods. It highlights the importance of child mortality and suggests specific epidemic causes. The comparison between land and sea mortality is innovative but underdeveloped.
