Overall

population

with the number of people aged between 35 and 64 and 65+ showing upward trends, with the former being projected to become the most prevalent

group

by 2050. It is

clear that the 15-34

group

, albeit dominant from 1950 until the present day, is expected to go through a downturn by 2050. In 1950, New Zealand’s

population

aged between 15 to 34 was 32.5%, ranking first among the 4 groups surveyed.

This

(27.5%), 35-64 (15%) and 65+ (10%).

Thereafter

, despite rising steadily to its high of 45% in the first half, saw a mild drop to 42.5% in 1990, followed by another steeper decline to only 30% in 2010. In the meantime, the

showed a steady downturn and eventually reached 20% in 2010,

whereas

the two oldest groups 35 to 64 and over 65 experienced increases, with the figures amounting to 20% for the former and 15% for the latter. By 2050, New Zealand’s

aged 35 to 64 and over 65 will have reached 35% and 20% respectively, with the former
