Task 1: The line graph shows the percentage of New Zealand population from 1950 to 2050.

The given line chart sets out New Zealand’s

population

from 1950 to the present day and projections

2050.

Overall

, the demographical figures tell us that New Zealand has an ageing

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

also

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

was followed by the figure for the 0-14

group

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

Thereafter

the 15-to-34 age

group

, 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

population

aged between 0-14

also

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

population

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

group

being projected to be the dominant part of the

population

. Demographics for the two youngest groups,

on the other hand

, are expected to drop, eventually amounting to a little lower than 30% for the 15-to-34

group

and a negligible 10% for the 0-to-14

group

.
