Solomon Islands: Population and Cities


According to Countryaah website, the Solomon Islands have about 550,000 residents.

Ethnic groups

Melanesians 93%, Polynesians 4%, Micronesians 1.5%, Europeans 0.8%, Chinese 0.3%, others 0.4%


Albinism is particularly widespread in some regions of the Solomon Islands. These are Santa Cruz, the Reef Islands, and the Duff Islands. For the albinos, everyday life is quite difficult under the climatic conditions.

Their life expectancy is therefore relatively low. They seldom find a partner because few want to risk passing the disease on to their children.


The main religion is Christianity with roughly the following groups:

Anglicans 45%, Catholics 18%, United Methodists and Presbyterians 12%, Baptists 9%, Seventh-Day Adventists 7%, Protestants 5% and native faiths 4%.


The official language is English, which surprisingly is only spoken by 1-2% of the population.

In contrast, Pidgin-English and Tok-Pidgin, which belong to the so-called contact languages, are the most widely used languages. There are a total of 120 native languages. The Solomon Islands, like the neighboring state of Vanuatu, belong to a region with the highest density of different languages.

Due to the various migratory movements from Southeast Asia, Papua New Guinea, Taiwan and other countries as well as the remoteness within and between the islands, this unique language diversity was able to develop and maintain it to this day.

Tidal range in the Solomon Islands

In the Solomon Islands, the mean tidal range is around 1 to 2 m.


The world’s highest tidal range can be found in the Bay of Fundy in Canada, where it is up to 16 meters, and at spring tide even over 20 meters. The Bay of Fundy is located on the Atlantic between the Canadian provinces of New Brunswick and Nova Scotia, which is called Nova Scotia in German and whose capital is Halifax.

On the German North Sea coast it varies between one and three meters. In the western Baltic Sea, on the other hand, the tidal range is only 0.3 meters, while it is barely noticeable in the eastern Baltic Sea.

Longitude and latitude

The Solomon Islands extend over the following geographical latitude (abbreviation Δφ) and geographical longitude (abbreviation Δλ):

Δφ = from around 5 ° to around 12 ° south latitude Δλ = around 154 ° to around 162 ° east longitude

Legal time

For the Solomon Islands, the following value applies to Central European Time (CET), i.e. the time without summer time. A minus sign means that it is earlier there, a plus sign that it is later than CET:

Δt (CET) = + 10 h

The highest point of the sun in Honiara

Honiara, the capital of the Solomon Islands, is located at a southern latitude of 09 ° 28 ‘and thus in the middle of the tropics.

If the sun or its image point is exactly above the city or the island, i.e. at 09 ° 28 ‘S, the sun is exactly perpendicular to the sky. In Honiara this happens exactly twice a year, roughly one month before March 21st and one month after September 21st.


If the image point of the sun (declination) is north of the latitude of Honiara, the sun is not in the south at noon, as in our latitudes, but in the north. The sun then moves from east to north to west, where, like us, it sets.
