Day 1: Fractions

Share of deaths by age group in Sweden, 1950-2023

$A stacked area chart showing how the age distribution of deaths in Sweden has changed between 1950 and 2023. The chart reveals a clear shift towards deaths occurring at older ages. The bottom of the chart shows that child mortality (ages 0-9) has dramatically decreased from about 5% to less than 1% of all deaths. The middle sections show declining shares for ages 20-79. The most striking change is visible in the top sections, where deaths among those aged 80-99 have become dominant, now accounting for 58% of all deaths, while deaths of centenarians (100+) have increased from a tiny fraction to a visible portion of the total. A notable bump in the elderly death shares appears in 2020, reflecting the impact of the COVID-19 pandemic.$
