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 chart illustrates the proportion of New Zealand residents over 50 years commencing from 1950 and an estimation of 2050.
Overall, there is a rise in the percentage of 0-14 age groups and 38 to 45-year-old people, while a decline was seen in the figures for elderly people and the 25-37s. In addition, the elderly in New Zealand consistently have the largest proportion over the period examined.
In 1950, the percentage of senior citizens in New Zealand started at 60%, followed by a slight rise to 70%, and became the highest share over the timescale, before ending the period with a projection of a significant decrease to around 55% in 2050. Conversely, the share of those aged 38-45 witnessed a dramatic growth from around 25% in 1950 to precisely 40% in the final year surveyed, being the second-highest number recorded at the time.
The proportion of people who were aged 25 to 37 in New Zealand began at approximately 22% in 1950. However, this figure underwent a period of constant decrease, simultaneously switching places with the percentage of the 0-14s in 2000, before becoming the age group that has the smallest population at a mere 2% in 2050. While there was a fluctuation in the percentage of people aged 0 to 14 population in the first 50 years, before likely to rise to exactly 20% in 2050.
