The table displays how New Zealand’s population changed between 2011 and 2012. It can be seen that while there was an increase in this country’s population, the number of people under 39 decreased, whereas the figure for those over 40 rose. Additionally, people between 15 and 39 years of age made up the most populous demographic in both years.
In 2011, there were nearly 1.58 million New Zealanders in the 15-39 age group, and this was closely followed by the 40-64 cohort, with 1.33 million people. These two demographics altogether accounted for two-thirds of New Zealand’s population, and of the remaining third, nearly 900,000 was the figure for children under 15. There were fewest people over 65 years old, with 573,946.
By 2012, the population of this country had grown by 0.6%, from about 4.38 million to over 4.4 million New Zealanders. Seniors older than 65 experienced an increase of 4% to nearly 600,000 people, by far the most significant change shown. The number of people between 40 and 64 years of age, meanwhile, had risen by approximately 8,000. While the remaining demographics shrank by no more than 3,000 for each cohort, the 15-39 age group was still the most populous segment, making up over a third of New Zealand’s 2012 population.
