How many additional days per week did people live in between 2000-2016 compared to 1960-2000?


What's going on?

World Health Organization (WHO) has stated that 72 years is the average life expectancy at birth of the global population in 2016. Life expectancy is essential as it gives an estimation of how long people could live, and it’s continually improving or receding over the years. It is widely viewed as a key measure of a country’s population health, and this is affected by various aspects such as the health system, economy, genetic, and environment.


Based on a research by Datawrapper of the additional days per week people live in between 2000 to 2016 compared to 1960 to 2000, they found that Zimbabwe has the fastest increase in life expectancy with an additional of 8.3 days. This is followed by Botswana, which saw an increase of 8.1 days and Zambia with 7.6 days. On the other hand, Syria has the slowest growth in life expectancy with a decrease of 4.9 days. Tunisia followed suit with a decline of 4.3 days and Libya with 4.2 days.


In 2016, the United States was ranked at 43rd in the world with an average lifespan of 78.7 years. It is predicted that the life expectancy of Americans will increase by more than a year to 79.8 years by 2040. The other top countries with the highest average life expectancies by 2040 are Spain with 85.8 years, Japan with 85.7 years, Singapore with 85.4 years, Switzerland with 85.2 years and Portugal with 84.5 years.
