Cumulative growth of population in Cook Islands

Total population refers to all residents of a country or territory, regardless of legal status or citizenship. It reflects demographic dynamics driven by births, deaths, and migration.
Cumulative population growth since 2010 measures the total percentage change in population since that base year. By accounting for the compounded effect of changes over time, this indicator highlights long-term trends rather than short-term fluctuations. It reflects the combined effect of natural increase (births minus deaths) and net migration (immigrants minus emigrants) since 2010.
Positive values indicate population expansion, while negative values indicate decline.
Calculation method: Each value on this chart represents the total percentage change since 2010. It is calculated by taking the difference between the Total Population of the year shown and the Total Population of 2010, divided by the 2010 value.
