The given line graph depicts and predicts the trends of four population groups in New Zealand throughout 1950-2050. The apparent visualization of the population indicates the threat of ageism in New Zealand as the age of 35-64 and over 65 overall rise to become dominant, according to the projection. Regarding the upward tendencies, the initial figures of both age groups approximately resemble with 10% and 15%.

In the 50 following years, this drop is forecast to be slower than the former period. The ratio of children, at the same past time, experience a gradual decrease of around 5% while the period of 2030-2050 might see the tendency steady decline.
