Tonga Population Pyramid 2017
Tonga in 2017
In 2017, Tonga had a total population of 105,356 people. A decade earlier, in 2007, the population was still 106,726; it has declined by 1.3% since.
The median age was 21.9 years, and for every 100 people of working age (15–64) there were 63.2 children under 15 and 10.5 people aged 65 or over. This is an expansive pyramid — each cohort of children is larger than the one above it, the signature of high birth rates and rapid growth.
