Annual Change
Growth in theTotal Population Estimate
Shows a significant decline from 2019 to 2020, followed by a steady increase from 2021 to 2024.
The total population surpassed 25,000 in 2024, reaching its highest level within the observed period.
Resident Population
The resident population remained relatively stable, with minor fluctuations between 16,000 and 18,000.
This indicates that while some residents may have left, the core resident population has remained fairly constant.
Divergence Between Total and Resident Populations
The graph indicates a positive trend in population recovery post-pandemic. Since 2021, the gap between total and resident population estimates has increased significantly, likely due to a rise in non-residents such as tourists and temporary workers.
Quarterly reports on the total and resident population estimate based on vital events of births and deaths plus net migration data derived from tourism and migration data. The Population and Vital Statistics reports on the total and resident population estimate base on vital events of birth and deaths plus net migration data derived from tourism migration data. It also reports on the various vital events such as births, deaths and marriages that occurred within the Cook Islands. Some basic demographic crude rates such as for birth, death and infants deaths including natural increase are also reported in this release.

Computation of Crude Rates: Crude rates of birth, death and infant deaths are also compiled from these events. The formula used in computing these rates are as follows:
Crude Birth Rate = Total Births/Total Resident Population * 1,000 Crude Death Rate = Total Deaths/Total Resident Population * 1,000 Infant Mortality Rates = Total Infant Deaths/Total Births * 1,000 Natural Increase = Total Crude Birth Rate less Crude Death Rate
Data Source: The records of births, deaths and marriages are compiled from the records of the Births, Deaths and Marriages Registrar of the Ministry of Justice. For the islands outside of Rarotonga, the Deputy Registrars of each island furnish these records directly to the Cook Islands Statistics Office.
Coverage: All records are compiled for each inhabited island of the Cook Islands and are tabulated by the date of occurrence of the event. Often these records are reconciled with the Ministry of Health (MOH) records to ascertain the compilation of one indicator for the Cook Islands.
