During 2018 Tonga population is projected to increased by 454 people and reach 107,682 in the beginning of 2019. The natural increase is expected to be positive, as the number of births will exceed the number of deaths by 2,103. If external migration will remain on the previous year level, the population will be declined by 1,649 due to the migration reasons. It means that the number of people who leave Tonga to settle permanently in another country (emigrants) will prevail over the number of people who move into the country (to which they are not native) in order to settle there as permanent residents (immigrants).
According to our estimations, daily change rates of Tonga population in 2018 will be the following:
As of 1 January 2018, the population of Tonga was estimated to be 107,228 people. This is an increase of 0.42 % (452 people) compared to population of 106,776 the year before. In 2017 the natural increase was positive, as the number of births exceeded the number of deaths by 2,094. Due to external migration, the population declined by 1,642. The sex ratio of the total population was 1.000 (1,000 males per 1 000 females) which is lower than global sex ratio. The global sex ratio in the world was approximately 1 016 males to 1 000 females as of 2017.
Below are the key figures for Tonga population in 2017:
Tonga population density is 143.0 people per square kilometer (370.3/mi2) as of March 2018. Density of population is calculated as permanently settled population of Tonga divided by total area of the country. Total area is the sum of land and water areas within international boundaries and coastlines of Tonga. The total area of Tonga is 750 km2 (290 mi2) according to the United Nations Statistics Division .
As of the beginning of 2018 according to our estimates Tonga had the following population age distribution:
|- percentage of population under 15|
|- percentage of population between 15 and 64 years old|
|- percentage of population 65+|
In absolute figures (estimate):
We prepared a simplified model of the population distribution pyramid which is broken down into 3 main age groups. The groups are the same as we used above: population under 15, between 15 and 64 and population which is over 65 year old.
Note: The pyramid provided is not corresponding to data given above because the age groups have different number of years.
As we can see the Tonga population pyramid has an expanding type. This type of pyramid is common for developing countries with high birth and death rates. Relatively short life expectancy, as well as low level of education and poor health care are also describe such kind of population age distribution model.
Dependency ratio of population is a ratio of people who are generally not in the labor force (the dependents) to workforce of a country (the productive part of population). The dependent part includes the population under 15 years old and people aged 65 and over. The productive part of population accordingly consists of population between 15 and 64 years.
This ratio shows the pressure on productive population produced by the dependent part of population.
The total dependency ratio of population in Tonga is 76.3 %.
As we can see the dependent part of population is comparable to the working part. It means that each working person in Tonga must provide goods for himself and cover expenditure on one child or aged person additionally. The value of 76.3 % shows that the pressure on productive population in Tonga is very high.
Child dependency ratio is a ratio of people below working age (under 15) to workforce of a country.
Child dependency ratio in Tonga is 65.6 %.
Aged dependency ratio is a ratio of people above working age (65+) to workforce of a country.
Aged dependency ratio in Tonga is 10.7 %.
Life expectancy at birth is one of the most important demographic indicator. It shows the number of years a newborn infant would live assuming that birth and death rates will remain at the same level during the whole lifetime.
Total life expectancy (both sexes) at birth for Tonga is 75.2 years.
This is above the average life expectancy at birth of the global population which is about 71 years (according to Population Division of the Department of Economic and Social Affairs of the United Nations).
Male life expectancy at birth is 73.8 years.
Female life expectancy at birth is 76.6 years.
According to our estimates 66,918 persons or 99.4% of adult population (aged 15 years and above) in Tonga are able to read and write. Accordingly about 406 adults are illiterate.
Literacy rate for adult male population is 99.35% (33,303 persons). 218 are illiterate.
Literacy rate for adult female population is 99.45% (33,615 persons). 188 are illiterate.
Youth literacy rates are 99.36% and 99.54% for males and females accordingly. The overall youth literacy rate is 99.45%. Youth literacy rate definition covers the population between the ages of 15 to 24 years.
