New Zealand Population Pyramid 2031
New Zealand in 2031
In 2031, New Zealand is projected to have a population of 5,432,482 people. That would be 6.4% more than in 2021 (5,107,696).
Half of the population would be younger than 40.5 years, with 16.6% children under 15 and 20.1% aged 65 or older. The pyramid is constrictive: cohorts of children are smaller than those of their parents, reflecting low fertility and an ageing population.
