This question can be addressed by measuring inequality in the distribution of years of life within countries, in the same way that we measure, for example, inequality in the distribution of incomes. The idea is to estimate the extent to which a small share of a country's population concentrates a large 'stock of health hence living much longer than most of the population in the same country. The following visualization presents huid estimates of inequality of lifetimes as measured by the mortality gini coefficient. A high Gini coefficient here means a very unequal distribution of years of life that is, large within-country dispersion around the average number of years that people live. These estimates are from Peltzman (2009) 2, where you can find more details regarding the underlying sources and estimation methodology. For an analogous discussion of inequality in the context of incomes, see our entry. As can be seen in the chart below, inequality in health outcomes has also fallen within countries.

life expectancy above 40 (Belgium had the highest life expectancy with just 40 years). In 1950 life expectancy in all countries was higher than in 1800, but we can see that inequality grew substantially. This happened because very large improvements in health outcomes took place in some countries (mainly the richer countries in Europe and North America while others (notably India and China) made only little progress. In 2012 (green line we can see again an improvement in life expectancy across all countries; yet interestingly, improvements in this last period implied a reduction in inequality. This happened through very large recent improvements in life expectancy across developing countries. The conclusion is that the world developed from equally poor health in 1800, to great inequality in 1950, and back to more equality today but equality at a much higher level. Life expectancy of the world population, 1800, 19 1, inequality in life expectancy within countries decreased hugely in the long run. We have already pointed out that recent improvements in life expectancy across developing countries have implied substantial reductions in global health inequalities. But has inequality in life expectancy also implied large within-country reductions in health inequality?
The chart below also shows large historical changes in life expectancy estimates for other countries. Notice, for example, that a century ago life expectancy in India and South Korea was as low as 23 years and a century later, life expectancy in India almost tripled, and in south Korea almost quadrupled. You can switch to the map view in this visualization by clicking on the corresponding tab, in order to compare life expectancy across countries. The map shows that, despite long-run cross-country convergence, there are still huge differences between countries: people in some sub-Saharan African countries have a life expectancy of less than 50 years, compared to 80 years in countries such as Japan. The increase in life expectancy happened to a significant extent because of changing mortality patterns at a young age, but this was not the only reason: life expectancy increased for people at all ages. Have all countries in the world experienced increasing life expectancy? The visualization below shows the cumulative share of the world population (horizontal axis) against the corresponding life expectancy (vertical axis) at different points in time (colored lines). You can think of this as a bar-chart of life expectancy by country, but where countries have been fbto ordered by life expectancy, and the width of each bar has been drawn proportional to each country's share of the world population.
Global health - our World in Data
I.1 Life expectancy, context, one way to assess health in a population is by looking at mortality data. Life expectancy is the most commonly used measure to aggregate mortality data in order to describe a population's health. It measures how many years, on average, a person is expected to live based on current age and sex-specific death rates. Further in-depth information on life hiv expectancy, including definitions, data sources, historical trends and much more, can be found in our dedicated entry. How has cross-country life expectancy changed in the long-run? The following visualization summarises available life expectancy data over the last few centuries. The estimates from the uk the country for which we have the longest time-series show that life expectancy before 1800 was very low, but since then it has increased drastically. We can see that in less than 200 years the uk doubled life expectancy at birth. And the data shows that similarly remarkable improvements also took place in other European countries during the same period.
