Society finch lifespan3/20/2024 Until recently, in some countries such as India, Bangladesh, Pakistan, and Iran, male life expectancy was higher than female life expectancy. You can use the settings to explore this data for other countries. In Russia and Poland, for example, the overall sex gap in life expectancy is still large, due to higher death rates in young and middle aged men than women. The chart below shows that there are also differences between countries. You can see that the sources of the gap have shifted over time: most of the gap now comes from middle and older age death rates, with infant and child death rates making only a small contribution. 12 As smoking has fallen, the gap has narrowed. Research suggests that the rise in smoking – which was especially prevalent among men – was a significant contributor to this widening gap. As the chart shows, this came from sex differences in mortality in youth and older ages specifically. You can see that both the overall sex gap in life expectancy and its composition have changed over time.īefore 1900, half of the gap was due to sex differences in mortality among infants.ĭuring the World Wars, the gap spiked due to a surge in death rates in young men.īut, over the twentieth century, the gap also widened gradually. Male life expectancy is shown on the horizontal axis and female life expectancy on the vertical axis.Īll countries lie above the diagonal line, meaning female life expectancy is higher.īut the chart also shows that the gap varies between countries: some are much further from the line than others. It compares female and male life expectancy across countries. You can see the difference from the chart below. Women tend to outlive men around the world. The sex gap in life expectancy is not a constant In this article, we’ll look into the sex gap in life expectancy: how it arises, how it varies around the world and how it has shifted over generations. What causes these differences? Is it because women outlive men at old ages? Or because young men are more likely to experience accidents and violent deaths? In 2021, this difference amounted to a 5-year gap in global life expectancy: the average life expectancy was 73.8 years for women versus 68.4 years for men.
