The graph illustrates how the figures for births and deaths in New Zealand changed from 1901 to 2011.
Overall, the births rate was consistently higher than the death level thoughout the beginning of the period, although both figures are expected to converge by the end of the century. Both trends are projected to decline gradually in the future.
The birth level in New Zealand experienced significant fluctuations during the first half of 20th century. It rose sharply from around 25 births per 1000 people in 1901 to nearly 66 in 1960s. After reaching this point, the figure undergone a steadly decline over the following decades. By 2001, the figure had fallen to just above 50, and forecasts suggest that it will continue its downward trajectory, reaching approximately 45 by 2101.
In contrast, the death rate showed much more stability. Starting at about 20 per 1000 people in 1901. It fluctuated only slightly during the 20th century, generally remaining with the range of 10 to 15. Unlike the birth rate, however; it is predicted to rise gradually in the future. By 2101, the death rate is expected to increase to nearly 30.
