2023 population pyramid
This is the population pyramid for the Cook Islands. A population pyramid illustrates the age and sex structure of a country's population and may provide insights about political and social stability, as well as economic development. The population is distributed along the horizontal axis, with males shown on the left and females on the right. The male and female populations are broken down into 5-year age groups represented as horizontal bars along the vertical axis, with the youngest age groups at the bottom and the oldest at the top. The shape of the population pyramid gradually evolves over time based on fertility, mortality, and international migration trends.

For additional information, please see the entry for Population pyramid on the Definitions and Notes page.

Polynesians from Tahiti were probably the first people to settle Rarotonga -- the largest of the Cook Islands -- around A.D. 900. Over time, Samoans and Tongans also settled in Rarotonga, and Rarotongans voyaged to the northern Cook Islands, settling Manihiki and Rakahanga. Pukapuka and Penrhyn in the northern Cook Islands were settled directly from Samoa. Prior to European contact, there was considerable travel and trade between inhabitants of the different islands and atolls, but they were not united in a single political entity. Spanish navigators were the first Europeans to spot the northern Cook Islands in 1595, followed by the first landing in 1606, but no further European contact occurred until the 1760s. In 1773, British explorer James COOK spotted Manuae in the southern Cook Islands, and Russian mapmakers named the islands after COOK in the 1820s. English missionary activity during the 1820s and 1830s converted most of the population to Christianity.

Fearing France would militarily occupy the islands as it did in Tahiti, Rarotongans asked the UK for protectorate status in the 1840s and 1860s, a request the UK ignored. In 1888, Queen MAKEA TAKAU of Rarotonga formally petitioned for protectorate status, to which the UK reluctantly agreed. In 1901, the UK placed Rarotonga and the rest of the islands in the New Zealand Colony, and in 1915, the Cook Islands Act organized the islands into one political entity. It remained a protectorate until 1965, when New Zealand granted the Cook Islands self-governing status. The Cook Islands has a great deal of local autonomy and is an independent member of international organizations, but it is in free association with New Zealand, which is responsible for its defense and foreign affairs. In September 2023, the US recognized the Cook Islands as a sovereign and independent state.

Telecommunication systems

general assessment: demand for mobile broadband is increasing due to mobile services being the primary and most wide-spread source for Internet access across the region; Telecom Cook Islands offers international direct dialing, Internet, email, and fax; individual islands are connected by a combination of satellite earth stations, microwave systems, and VHF and HF radiotelephone (2020)

domestic: service is provided by small exchanges connected to subscribers by open-wire, cable, and fiber-optic cable; nearly 41 per 100 fixed-line and about 100 per 100 mobile-cellular (2021)

international: country code - 682; the Manatua submarine cable to surrounding islands of Niue, Samoa, French Polynesia and other Cook Islands, the topography of the South Pacific region has made Internet connectivity a serious issue for many of the remote islands; submarine fiber-optic networks are expensive to build and maintain; satellite earth station - 1 Intelsat (Pacific Ocean) (2019)
