Beyond the exodus of May–June 1940: Internal migration in France during the Second World War

“…This would reveal the extent of outward migratory flows, and whether male and female migration followed different trends during World War II. Using the same approach as for female migration, I used the data collected by Bonnet (2020) to calculate male migration balances for each year between 1939 and 1946, and a partial answer to the second question is outlined in Online Appendix 4, which compares female (Panel A) and male (Panel B) migration balances between 1939 and 1940. The two maps are almost identical.…”

“…Bonnet ( 2020) and the curators of both the Canadian Human Mortality Database and the Japan Human Mortality Database have used this method to estimate life tables at the local level in France since 1901, in Canada since 1921, and in Japan since 1975. Nevertheless, as revealed by Bonnet (2020), distributing the intercensal migration flow proportionally to the time elapsed since the first census is inappropriate in times of war, when migratory movements are faster and massive. This leads to biased estimates of départemental life expectancies during the Second World War.…”

“…To conclude, I sought to understand to what extent refugees continued to return after 1946 or remained settled in their new homes. Using the data collected by Bonnet (2020) and the methodology used for migration between 1939 and 1946, I calculated the female populations for each year of the period 1946-1954 and deduced the départemental variations of populations due to migration for each year. Figure 7 compares the cumulated migration balances for 1939-1946with those for 1939-1947(Panel A), 1939-1949(Panel B), 1939-1951(Panel C), and 1939-1954.…”

Estimating Subnational Excess Mortality in Times of Pandemic. An application to Frenchdépartementsin 2020

“…For illustrative purposes, we present excess mortality measures by losses/gains in life expectancy at age 60 (e 60 ) in 2020 for 95 départements of Metropolitan France, which correspond to the third level of the Nomenclature of Units for Territorial Statistics (NUTS) used by Eurostat. French Human Mortality Database [37] provides annual deaths (D) and population at 1st January by single age at death (with an open age interval 95+), sex, and département for each year between 1970 and 2020. We define exposures (E) as the mean of populations at 1st January for two consecutive years.…”

Influenza mortality in French regions after the Hong Kong flu pandemic

“…For the statistical analysis, we also use population data by department, sex, and age at January 1. These populations are calculated from age-specific populations in census years and annual vital statistics (age-specific deaths and births) using a methodological protocol close to that of the Human Mortality Database (Bonnet 2020;Barbieri et al 2015). To determine the population on January 1 of years in an intercensal period, we adjust the population at the initial census by both observed deaths and by an estimate of migration flow since the initial census.…”
