The Cook Islands' population is projected to have slipped past its peak: from a high of 20,869 in 1971, it is projected at 12,826 in 2026. That is down 13% from 14,693 in 1950. The population is shrinking by 3.26% a year. Population density sits at 53 people/km². Half the population is younger than 38.1 years, and the age structure is steadily tilting older: the median is projected to reach 38.3 by 2050. Women outnumber men, at 95 males per 100 females. By 2100, UN projections see it falling to 7,904 (-38% from 2026).
