The table illustrates the population of New Zealand from 2011 to 2012 by age group, alongside giving the percentage of change.
Overall, total population of New Zealand increased minimally from 2011 to 2012. The population of under 15 and 15-39 accounted for a larger share of total population compared to the two remaining age brackets, although these two groups were on a similar decline. Additionally, it is clear that the population aged 65 and above rose the most significantly while the 40-64 group rose more slightly.
Regarding total population of New Zealand, this figure rose from 4,381,269 to 4,410,284, representing an increase of 0.6%. The groups for under 15 and 15-39 were on the similar fall of 0.2%, from 898,160 to 896,364 and from 1,577,256 to 1,574,102, respectively. However, the total of these two groups still outnumbered two remaining older groups.
In terms of the older population, the number of people aged 65 and over saw the most considerable change of rising by 4%, from 573,946 to 596,903, but this was still far fewer than those younger age brackets. In addition, the 40-64 age bracket also observed an upward trend, but only slightly, by 0.6%, from 1,331,907 to 1,339,898.
