Update on all-cause mortality for the period from June 22 to 28, 2026
Health surveillance data on all-cause mortality for the week of June 22–28, 2026, show an increase of nearly 30% in all-cause deaths compared with the previous week.
These data are derived from electronic death certificates; they include the figures published on Sunday, June 28, which covered the period from June 24 to 26, and are still incomplete at this stage.
As part of the Heat Wave and Health Alert System (SACS), a report on excess mortality during the June heat wave will be published three weeks after the end of the heat wave.
Santé publique France continuously analyzes fluctuations in all-cause mortality throughout the year. This analysis is published weekly in the “All-Cause Mortality” bulletin.
Here is what we observed during the week of June 22–28 based on electronic death certificates (unconsolidated data):
An increase in all-cause deaths among people aged 45 and older, particularly among those at home
A 29.1% increase, corresponding to 2,025 additional deaths compared to the previous week, (8,973 deaths across all ages and causes were recorded during the week of June 22–28, 2026, compared to 6,948 during the week of June 15–21)
This increase applies to people aged 45 and older (+29.7%, or +2,001 deaths) and was observed across all types of places of death, with a particularly marked increase at home (data to be consolidated): at home (+91%), in nursing homes (+37%), and in healthcare facilities (+19.7%).
An increase in deaths from all causes by region
The number of deaths certified electronically has risen compared to the previous week in all regions of mainland France, except in Occitanie and Auvergne-Rhône-Alpes.
The increase is particularly pronounced in Île-de-France (+62.8%, or +619 deaths), Centre-Val de Loire (+47.3%, or 121 deaths), Normandy (+53.1%, or 216 deaths), Brittany (+36.0%, or +129 deaths), Pays de la Loire (+62.0%, or +178 deaths) Nouvelle-Aquitaine (+28.1%, or 264 additional deaths), and Hauts-de-France (+27.7%, or 155 additional deaths).

Monitoring of All-Cause Mortality. Bulletin of July 3, 2026.
This surveillance is based on the reporting of electronic death certificates; it is not exhaustive and typically captures about 60% of all deaths.
This analysis relies on two data sources:
One is a reactive system based on the submission of electronic death certificates. While not exhaustive, it typically captures about 60% of national deaths. The system’s coverage remains inconsistent across regions and, more importantly, depending on the type of place of death: it captures 25% of deaths occurring at home, 45% of those in long-term care facilities, and nearly 80% in hospitals. Statistics derived from this source should therefore be interpreted with caution, as the data are underestimated, particularly in areas and for places of death that are least covered by the system, such as deaths at home.
The other source, which requires a longer consolidation period, is based on a sample of approximately 5,000 civil registry offices, which automatically transmit their data to INSEE. This network covers 84% of national mortality.
The data should be interpreted with caution because they are underestimated, particularly for areas and places of death that are less well covered by the system, such as deaths at home. Mortality will therefore be higher than these initial figures.
These monitoring results are published in a weekly bulletin titled “All-Cause Mortality.”
The health impact is assessed after the fact, based on two time frames.
Excess all-cause mortality during a heat wave
Based on data from civil registry offices, the estimated number of excess all-cause deaths during heat waves is obtained by comparing the observed “all-cause mortality” to an expected reference “all-cause mortality.”
As part of the SACS surveillance program, an initial estimate of the impact on “all-cause mortality” is calculated and published in a special bulletin three weeks after the end of each heat wave (the time required to consolidate data on approximately 95% of deaths).
All-cause deaths attributable to heat
Santé publique France has also developed a method to estimate, at the departmental level, the annual mortality attributable to heat exposure among the general population, for all age groups and for people aged 75 and older.
The objective is to illustrate the extent to which the general population’s exposure to heat contributes to all-cause mortality, as well as its spatial and temporal trends. This will supplement the heatwave assessment at the end of the summer surveillance period, which focuses solely on excess all-cause mortality.
These two estimates are complementary. The estimate of excess all-cause deaths during heat waves can capture unexpected or indirect impacts that would not be accurately estimated by the attributable fraction calculation.
