About this chart

New Zealand has grown from about 1.9 million people in 1950 to 3.9 million in 2000 and 5.17 million in 2023, according to UN estimates. Growth is set to slow a lot: the UN's medium scenario adds roughly another half million by 2050, reaching 5.76 million, and then growth nearly stops.

The projected peak is about 5.87 million in 2078, with a small dip to roughly 5.81 million by 2100. World rank barely moves: 112th in 1950, 123rd in 2023 and 2050, and a projected 121st in 2100. Figures are from UN World Population Prospects 2024: estimates through 2023, medium-variant projections after.
