The bar chart illustrates the percentage of the population aged 65 and over in four global regions: North America, Europe, Oceania, and Asia in three different years.
Overall, all four regions show an increasing trend in the proportion of people aged 65 and over. Europe had the highest percentage throughout the period, whereas Asia recorded the lowest. In addition, North America consistently had a higher proportion than Oceania.
Europe consistently had a higher proportion than Asia in all three years. In 1990, Europe stood at 15%, compared with only 5% in Asia, a difference of 10 percentage points. By 2050, Europe is projected to reach 25%, compared with 15% in Asia. Therefore, the 10-percentage-point gap between the regions is expected to remain unchanged.
In 1990 and 2010, there was a constant difference of 3 percentage points between North America and Oceania. In 2010, North America recorded 15%, compared with 12% in Oceania. By 2050, the gap between North America and Oceania is expected to widen by 5 percentage points.
