Sézanne’s death rate, adjusted for age and care homes, is higher than in 54% of compared French towns
Care access and life expectancy are shown for context, not graded.
From 2016 to 2025, 859 residents of Sézanne died, against 702 expected from France’s death rates at each age: 22% more. Its two care homes for older people (223 places) count their residents as Sézanne’s; allowing for them, deaths were 11% below expected. The adjustment lowers most towns’ figures, so the comparison is what counts: the median of compared French towns is 12% below expected. The care-home adjustment is a TownRatings modeling step, not an official statistic.
