The table illustrates the population changes in New Zealand between 2011 and 2012, categorized by age groups. It also highlights the percentage change for each group over the period.
Overall, the total population experienced a slight growth, with notable increases in older age groups, particularly those aged 65 and above. In contrast, the population of younger age groups showed a marginal decline.
In detail, the total population grew from approximately 4.38 million in 2011 to around 4.41 million in 2012, representing a 0.6% increase. The most significant growth occurred in the 65+ age group, which rose by 4%, from 573,946 to 596,903 people. A moderate increase was observed in the 40-64 age bracket, which grew by 0.6%, adding roughly 8,000 individuals.
Conversely, both the under-15 and the 15-39 age groups experienced slight declines of 0.2% each. The number of individuals under 15 fell from 898,160 to 896,364, while the 15-39 group decreased from 1,577,256 to 1,574,102.
In summary, while New Zealand’s total population showed modest growth during the period, the data indicates an aging population, with younger age groups declining slightly and older groups, especially the elderly, increasing at a much higher rate.
