The Cook Islands, a small island nation in the South Pacific, has experienced unique demographic changes over the past seventy years. Unlike many rapidly growing nations, the Cook Islands has maintained a relatively stable but small population base. In 1950, the population stood at 15,000 people, and by 2024 it was estimated at just 14,000 people. Projections suggest that the population will continue to decline to around 8,000 by 2100.

Cook Islands’ Historical Population Growth (1950–2024)

From 1950 to the early 1970s, the Cook Islands’ population rose modestly:

• 1950: 15,000
• 1970: 20,000 (a local peak)
• 2000: 16,000

This early growth reflected post-war recovery and high fertility rates. However, emigration to New Zealand and Australia soon became a defining factor, leading to slower growth and eventual decline.

Population in the 21st Century

By the 2000s, the Cook Islands’ population had stabilized around 15,000–18,000. However, continued outward migration for education and employment opportunities limited natural growth.

• 2010: 17,000
• 2020: 16,000
• 2024: 14,000

The most recent numbers show a gradual decline, highlighting the challenges of retaining population in a small island economy.

Cook Islands’ Future Population Projections (2025–2100)

The long-term forecast shows that the Cook Islands’ population is expected to decline steadily throughout the century:

Year	Population (thousands)
2025	13
2030	11
2050	9
2075	8
2100	8

By 2050, the Cook Islands is projected to have only 9,000 residents, falling further to 8,000 by 2100.
