The first chart illustrates data about the population (in millions), while the second chart presents the life expectancy (in years) in five countries between two years, 1914 and 2014.
Overall, it is evident that all countries maintained varying population sizes between those two years. Notably, Germany registered the highest population, while Spain accounted for the lowest figures. Meanwhile, in the second chart, the majority of countries showed relatively similar patterns of life expectancy.
In the first chart, Germany had the highest figures for population, accounting for a population of more than 63 million in 1914 and climbing to exactly 80 million residents by the end of 2014. Notably, the UK, Italy, and France had somewhat similar populations, with 38, 39, and 40.5 million in 1914, and reaching 62, 60, and 64 million by the end of 2014, respectively.
Regarding Spain, it reported the lowest population among the given countries, with 20 million in 1914 and peaking at 45 million in 2014.
In the second chart, all countries demonstrated relatively similar figures for life expectancy, accounting for ages not below 70 years old in 2014. In 1914, life expectancy varied across countries, accounting for 40 and 48 years in Spain and Italy, and 50 and 53 years for Germany and the UK, respectively, with France being responsible for the highest expectancy of 59 years.
