Life expectancy in Portugal, 1915-2020
Life expectancy in Portugal was 35.6 years in 1915, and over the course of the next century, it is expected to have increased by more than double, to 81.8 in 2020. Although life expectancy has generally increased throughout Portugal's history, there was a decline in the 1910s, as a result of the worldwide influenza pandemic, that is now known as the Spanish Flu. From this point onwards, Portugal's life expectancy increased at every five year interval.
