Full Sample Response 2
The line graph shows the historical and predicted trends
for the rate of birth and mortality in New Zealand for the
period from 1901 through to 2101.
At the start of the review period, the birth rate surpasses
the mortality rate. The forecasted data shows that the
mortality rate is likely to exceed the birth rate by 2041, at
which point, the large gap between the two will level off.
At the beginning of the period, the birth rate started at
20,000, peaking at around 66,000 in 1961, before fluctuating
between 50,000 and 65,000 until 2021. It is anticipated to
decline to around 45,000 births by 2101 slowly.
In contrast, the mortality rate started at just below
10,000 in 1901 and steadily rose throughout, reaching around
30,000 in 2021. This increase is expected to accelerate
between 2021 and 2041 when the number of deaths will
surpass the number of births. By 2051 the death rate will
stabilize at around 60,000 and decline marginally until the
end of the period.
