The line graph shows the percentage of New Zealand population from 1950 to 2050. Summarize the information by selecting and reporting the main features and make comparisons where relevant

The line graph illustrates the proportion of different age groups in New Zealand over the period of 100 years starting from 1950
Overall, it can be clearly observed from the graph that while the 0-14 age group and 38-45 year-olds are predicted to witness an upward trend, the opposite is estimated to be true for . 25-to 37-year-olds and age group over 65.
Look at the graph in more detail, starting at over 60% of population over 65 in 1950, New Zealand experienced a moderate increase and reached a peak at 70% in 1990. This was followed by a gradual decrease to 55% in the last period. Falling from 20% in 1950 to less than 10% in 1990, New Zealander aged 25-37 then rose slightly before being expected to decline and bottom out at 0% by 2050
People in the range of 0 to 14, meanwhile, remained stable at approximately 5% prior to 1990, before being thought to showing a steady increase to somewhere in the vicinity of 20% by 2050. The 38-45 age group went up from 20% to nearly 50% in 1990, followed by a marginal downturn in the following 20 years. In the future, the percentage of 38-45 year-old people in New Zealand is predicted to stabilize at 40%
