Line Graph #27 – The percentage of New Zealand population from 1950 to 2050.

The line graph shows the percentage of New Zealand population from 1950 to 2050.

Sample Answer :

The given chart illustrates past changes and future predictions of the New Zealand population over a 100-year period from 1950 to 2050.
Overall, people aged 65 and over accounted for the highest percentage of the New Zealand population throughout the period, including the predicted future figures. In addition, while the figures for the 25 to 37 year-olds and over-65 year-olds are predicted to decline over the 100 year period, those aged 14 and under and 38 to 45 years-old are expected to increase.

From 1950 to approximately 1990, the percentage of people aged 38-45 and those aged 65 and over both increased from around 25% to 50%, and 60% to 70% of the population respectively. Both these age groups then started to decline and are predicted to continue declining until 2050 to reach approximately 40% and 55% respectively.

The graph shows the opposite trend for the remaining age groups with 25 to 37 year-olds making up around 20% of the population and people aged 14 and under making up about 5%. By 2050, it is predicted that those aged 14 and under will make up 20% of the population, while those aged 25 to 37 will only be a very small percentage.
