The image presents a line graph indicating population growth by age groups in New Zealand from 1950 to 2050; the age groups are 0-14, 25-37, 36-45, and over 65. In 1950, percentages for age groups were as follows: 0-14 at 45%, 25-37 at 25%, 36-45 at 20%, and over 65 at 10%. In 1960, 0-14 rose to 50%, 25-37 dropped to 20%, 36-45 remained at 20%, and over 65 increased to 15%. By 1970, all groups except 36-45 increased by 5% each, but by 1980, 0-14 declined to 40%, 25-37 grew to 30%, 36-45 stayed at 25%, and over 65 reached 20%. By 1990, 0-14 dropped to 35%, 25-37 slightly grew to 35%, 36-45 maintained at 20%, and over 65 rose to 25%. In 2000, 0-14 went down to 30%, 25-37 shrunk to 30%, 36-45 increased to 30%, and over 65 remained at 25%. In 2010, 0-14 further decreased to 25%, 25-37 went up to 40%, 36-45 slightly rose to 35%, and over 65 fell to 20%. The forecast for 2020 anticipates 0-14 at 20%, 25-37 at 45%, 36-45 at 40%, and over 65 at 30%. By 2030, 0-14 is expected to continue at 20%, 25-37 at 55%, and 36-45 at 40%, with over 65 projected to hit 35%. In 2040, predictions suggest 0-14 remaining at 20%, 25-37 peaking at 60%, 36-45 staying at 40%, and over 65 climbing to 45%. Lastly, the 2050 outlook projects 0-14 at 20%, 25-37 reducing to 55%, 36-45 maintaining at 35%, and over 65 surging to 50%.

The line graph illustrates the proportion of four distinct age groups in New Zealand’s total population from 1950 to 2000 and its prediction for 2050.
Overall, New Zealand is facing the situation of an ageing population, with the dominance of elders over the age of 65. While the percentage of people aged 25 to 37 is decline, the opposite was true for other age groups.
In 1950, the figure of senior citizens over 65 years old was the highest, about 60%, while that of people aged 38 to 45 was lower, at approximately 25%. Over next 40 years, the percentage of two oldest groups increased to peak of 70% and nearly 50% in 1990, respectively. It is expected that proportion of thoes over the age of 38 will be decrease slightly around 10% in 2050.
The data for the 25 to 37 age group started at 20%, four times higher than teenagers under the age of 14, which was only 5% in 1950. The year 1960 witnessed a slight increase of 4% in the 25-37 age group. Meanwhile, the figure for childrens aged 0 to 14 was falled insignificantly, at 4% in 1990. In 2050, the proportion of younger groups aged 25 to 37 is anticipated to be dipping remarkably to 0%. In contrast, the amount of those in the 0-14s is predicted to be tripling and reaching 15%.
