Although during the 20 years from 1906 to 1926 the total population of the administrative territory of the Cook Islands has shown an increase, the population of Manihiki has decreased by 115 and that of Rakahanga by 25. Part of the decrease has been due to emigration to Rarotonga, where the better opportunities of obtaining employment have attracted settlers. This emigration has resulted in a Manihikian colony in Rarotonga.
