The table indicates and illustrates statistics about the changes in the population of New Zealand between 2011 and 2012 by comparing age groups.
Overall, the major conclusion that has been drawn by monitoring this table is that a significant positive alteration was made in the increase of individuals over 65. However, the number of residents from under 15 to 39 decreased gradually over this time frame.
At first glance, the number of people of all ages increased dramatically by 0.6%, from 4,381,269 in 2011 to 4,410,284 people in 2012. Furthermore, the proportion of the 40-64 age group followed the same trend and increased from 1,331,907 to 1,339,898 people. Surprisingly, the highest and most considerable change occurred in the elderly over 65, despite their comprising the lowest age group of society; about 4% from 573,946 members to 596,903.
On the downside, the numbers related to those under 15 years old and up to 39 years experienced a smooth decline (0.2% for both). In addition, the population under 15 diminished notably from 898,160 to 896,364, and there was a slight decrease of around 3000 individuals in the 15-39 generation, which made up 1,577,256 members of the population in 2011.
