Demographic Profile

New Zealand is located in Australia and New Zealand, a part of Oceania, and covers an area of 270,467 km². With a population of 5,287,500, the country has a population density of 19.7 inhabitants per square kilometer, which is below the global average of approximately 60 people per km².

The demographic structure of New Zealand reveals an aging population. The median age of 39.6 years means that half of the population is younger and half is older than this age. This aging population structure poses challenges for pension systems, healthcare provision, and the labor market, as the ratio of working-age to retired individuals continues to decline.

Health and Longevity

Life expectancy in New Zealand stands at 83.0 years overall — 81.2 years for men and 84.9 years for women. This places the country among those with high life expectancy globally, reflecting well-developed healthcare systems and living standards. The infant mortality rate is 4.0 per 1,000 live births, which is considered very low and indicates excellent maternal and infant healthcare.

Fertility and Population Growth

The total fertility rate (TFR) of 1.56 children per woman is below the replacement level of 2.1, which without immigration leads to population decline over time. The population is growing at a rate of 1.67% per year. At this rate, the population could double within approximately 42 years if trends continue.

Migration

Net migration in New Zealand is 18,766 people, meaning more people are moving into the country than leaving. The country serves as a destination for migrants, which helps offset low natural population growth and fills labor market needs.

Outlook

Based on current demographic trends, New Zealand's population dynamics reflect broader patterns seen across Australia and New Zealand. As the population ages, adapting social security systems and healthcare to serve a growing elderly population will be a key challenge.
