The graphs depict global population proportions by region and age group, between 1950 and projected up to 2040. Generally, in the graph for area, while the rural area’s figure witnessed a noticeable downward trend, the percentage for urban area underwent a gradual growth. On the other hand, age group’s graph recorded an significant decline in percentages for under-15 and 15-65 groups, whereas over-65 group’s proportion plunged, projecting to reach the highest figure by the end of the period.
As can be seen from the first line graph, the percentage for rural area started at 60% in 1950, being surpassed by urban area’s figure between 1960 and 1970 then halving to roughly 30% in 2000. After witnessing a slight decrease to 20% in 2010, it is expected to witness a drop by a half and end at 10% in 2040. By contrast, the proportion for urban area started at 40% before soaring to 80% in 2010. This is followed by an anticipation that it will have increased by a tenth to 90% by 2040.
Looking at the second graph, the proportion for under-15 group began at 45% in 1950 prior to experiencing a large decrease to approximately 30% in 2020. The projection is that it will reach its lowest point at 25% in 2040. Regarding 15-65 age group, its percentage started at 35% and steadily grew to just above 40% in 2000, witnessing a dip to about 37% in 2020. By 2040, it is set to decline to 30%. However, the figure for over-65 age group started at 20%, remaining almost stable until 1960. After surpassing under-15’s figure between 2010 and 2020, it is forecast to exceed 15-65 age group’s figure in 2030 and reach its peak at 45%, achieving the greatest proportion afterwards.
