The table illustrates how population divided into various age brackets varied from 2011 to 2012 in New Zealand.
Overall, although New Zealand demonstrated a rise in population between the two years, it experienced aging, with a considerable increase for those higher than 49 of age, and a moderate fall for the younger counterparts.
Upon closer inspection of the table, both age groups of under 15 and from 15 to 39 showed a decrease of 0.2% despite the fact that the figure for the latter roughly doubled those for the former in both years, the older group registered at 1.577.256 in 2011 and 1.574.102 in 2012.
On the other hand, the other age groups displayed a rise, the second most crowded sector with people aging from 40 to 64 fell from 1.331.907 to 1.331.898, equivalent to 0.6%. Similarly, the older age group also witnessed a growth of 0.4%, with 596.903 people in 2012. Generally, the total number of the population increased by 0.6%, from 4.381.269 to 4.410.284 people.
