New Zealand Population Pyramid 2100
New Zealand in 2100
By 2100, the population of New Zealand is expected to reach 5,812,294. The total would be almost unchanged from 2090 (5,836,503).
With a projected median age of 48.5 years, New Zealand would have a youth dependency ratio of 24.5 and an old-age dependency ratio of 56.1 per 100 people of working age. The narrow base of the pyramid marks a constrictive age structure: fertility below replacement level and a rising share of older people.
