Tonga: population and cities


According to Countryaah website, the Kingdom of Tonga has about 110,000 residents.

Ethnic groups

Mostly Polynesians and approx. 300 Europeans


The main religion is Christianity with the Free Wesleyan Church (Methodists) as the main group and about 15% Mormons.

This makes Tonga the country with the highest rate of Mormons. The Mormon Church is Tonga’s largest private employer. Especially the Mormons from the USA transfer a lot of money to Tonga. For the Tongans, membership of the Mormons also has very pragmatic reasons. You have the “ticket” to Honolulu and Salt Lake City and thus to the USA.

The highest point of the sun in Nuku’alofa

Nuku’alofa is located at a southern latitude of around φ = 21 ° ‘S and thus still in the tropics.

Since Nuku’alofa lies within the north and south parallels, the sun is perpendicular to the city and the country twice a year. That is roughly 10 days before December 21st and then again 10 days after December 21st.


If the image point of the sun (declination) is north of the latitude of Nuku’alofa, the sun at noon is not in the south as in our latitudes, but in the north. The sun moves from east to north to west, where, like us, it sets. This is the case on around 345 days a year.


The highest point in the country is an unnamed spot on Kao Island with a height of 1,033 m.


The largest lake is a crater lake on Tofua.

Other larger lakes are Lake ‘Ano and a crater lake on Nomuka with its springs. James Cook, Abel Tasman and Captain Bligh have already used these as a source of fresh water.


Tonga borders the Pacific Ocean with a total coast length of 420 km – more precisely, Tonga is located in the South Pacific, the so-called South Pacific. This region of the Pacific Ocean includes the Polynesian Islands as well as parts of Melanesia and Micronesia.
