The two line graphs illustrate the population data for Southern Pacific island nations between 1950 and projections for 2040. The first graph compares the total population between urban and rural areas, while the second shows the population distribution by age groups: under 15, 15-65 and over 65. Overall, despite the fact that urban population was higher than rural population, both experienced a significant increase, and the figures are expected to continue rising until 2040. It is also clear that the 15-65 age group makes up the majority of the population.
Looking at the first graph, the population of urban areas showed an upward trend, which significantly contributed to the total population. In 1950, only 7% of people lived in urban regions, while the figure for rural areas made up around 5%. The percentage of urban population witnessed a dramatic rise, reaching its highest of just above 25% in 2020, and the figures are speculated to continue rising to around 37%. In contrast, in terms of rural population, it also showed a growth, but it was not as dramatic as that of urban population, growing from 4% in 1950 to 7% in 2020, and this trend is set to continue with a projected value of nearly 8% in 2040.
Turning to the age population age distribution, the percentage of the youngest group accounted for around 3%, which is the same rate with people aged 65 and over, while the figure for the middle age group was twice as much as others. The proportion of population aged between 15 and 65 drastically grew, reaching a peak of around 33% in 2020, and this figure is projected to reach 35%. Differently, the other two age groups experienced some fluctuations; both under 15 and 65+ groups slightly increased to 5% in 2020, and it is forecasted that this figure will remain almost unchanged.
