The provided line graph delineates the data on changing ratio of birth and death in New Zealand over a two-century period starting from 1901 up to 2101.
Overall, it is explicitly observed that from the beginning of the period death rates increased and are predicted to have the same ceiling trend up to the end of the period, while birth rates fluctuated and are expected to dip until the end of the period.
According to the graph, initially in 1901, 20,000 New Zealanders were born which almost doubled the number of those who died (just under 10,000). Moreover, the number of births kept increasing with fluctuation until it peaked at approximately 65,000 in 1961. Similarly, the number representing death cases rose steadily throughout the same six decades.
On the other hand, starting from 2041 and onwards, the ratio of births to deaths will have opposite trends. As conspicuous, the number of births will gradually decrease to just over 40,000, while the death rates will skyrocket to reach the zenith of just under 60,000 in 2061 and 2081, then will mildly dip to about 55,000 at the end of the period.
