Insee Study Reveals Patterns in French Mortality Rates

The analysis highlights seasonal, weekly, and 'birthday' effects on death rates, with January 3rd as the deadliest day.

The study found that January 3rd is the deadliest day in France, with an average of 1,900 deaths, attributed to winter conditions and post-holiday medical procedures.
In contrast, August 15th sees the fewest deaths, benefiting from favorable summer conditions and being a public holiday.
Mortality rates are higher in winter, especially among those over 60, while summer sees a decrease in deaths, contradicting common beliefs about heat-related fatalities.
The 'Birthday effect' suggests a 6% increase in mortality on one's birthday, with young men experiencing a 24% rise, possibly due to risky behaviors.
Weekend and holiday periods generally see fewer deaths, with Tuesday noted as the most lethal weekday, likely due to resumed economic activities.
