Global Trends in Lifespan Inequality: 1950-2015

Lifespan inequality trends are influenced by the compositional change that has taken place during the last decades around the world. On the one hand, population growth has dramatically shifted the population shares distribution over time. On the other hand, impressive longevity gains have typically benefited most countries, but some have benefited more than others have. To gauge the effect that such structural changes have had on lifespan variability across and within countries we have run counterfactual analyses. This technique is helpful to identify the factors that have been more decisive in driving changes in global lifespan inequality. The empirical evidence presented here suggests that the declines in global lifespan inequality have been mainly driven by declines in within-country lifespan variability and, to a lesser extent, by longevity trends across countries. Population growth has played a minor role in this process.
