New Zealand Population Pyramid 2055
New Zealand in 2055
United Nations projections (medium variant) put the population of New Zealand at 5,804,685 in 2055. Compared with 2045, when the projection stands at 5,700,556, that represents growth of 1.8% over ten years.
With a projected median age of 44.5 years, New Zealand would have a youth dependency ratio of 25.2 and an old-age dependency ratio of 42.1 per 100 people of working age. This is a constrictive pyramid — its base is narrower than its middle, the signature of sustained low birth rates and population ageing.
