the line graph shows changes in the birth and death rates in new zealand between 1901 and 2101

The given graph depicts the number of the newborns and mortality in New Zealand from 1901 to 2021 and a trend until 2101. The unit is measured by number of people. Overall, the figures for the birth and death were substantial increments, despite varying considerably during a period between 1901 and 1981. Moreover, the rest of observed time span forecasts an upward trend in the death rates while the birth tends to decrease staggeringly. In detail, in 1901, the number of newborn infants was 20, 000, doubling the value of death. Over the next decade, there was a steep fluctuation in the birth rates between 20, 000 to 70, 000, with the peak in 1961. Meanwhile, the data for mortality stood the highest point with above 30, 000 cases after a long period of variation. The period between 2001 and 2021 has witnessed a rapid decline of over 5, 000 newborns, in contrast to a considerable increment in the mortality rates. In addition, the number of deaths tend to surpass the infants by about 1, 000 cases from 2041 after a period of almost being lower. However, during the period between 2061 and 2091, the mortality rates will have no considerable change, with 60, 000 cases, despite a gradual fluctuation. From 2091, the figures for the deaths will remain a higher position than the births although there will be a similar trend in both of them as the decline, to 57, 000 and 43, 000 cases respectively in 2101
