During 2018 Sao Tome and Principe population is projected to increased by 4,327 people and reach 205,111 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 5,572. If external migration will remain on the previous year level, the population will be declined by 1,245 due to the migration reasons. It means that the number of people who leave Sao Tome and Principe 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 Sao Tome and Principe population in 2018 will be the following:
As of 1 January 2018, the population of Sao Tome and Principe was estimated to be 200,784 people. This is an increase of 2.16 % (4,236 people) compared to population of 196,548 the year before. In 2017 the natural increase was positive, as the number of births exceeded the number of deaths by 5,454. Due to external migration, the population declined by 1,219. The sex ratio of the total population was 0.980 (980 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 Sao Tome and Principe population in 2017:
Sao Tome and Principe population density is 209.2 people per square kilometer (541.7/mi2) as of March 2018. Density of population is calculated as permanently settled population of Sao Tome and Principe divided by total area of the country. Total area is the sum of land and water areas within international boundaries and coastlines of Sao Tome and Principe. The total area of Sao Tome and Principe is 960 km2 (371 mi2) according to the United Nations Statistics Division .
As of the beginning of 2018 according to our estimates Sao Tome and Principe 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 Sao Tome and Principe 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 Sao Tome and Principe is 91.7 %.
As we can see the dependent part of population is comparable to the working part. It means that each working person in Sao Tome and Principe must provide goods for himself and cover expenditure on one child or aged person additionally. The value of 91.7 % shows that the pressure on productive population in Sao Tome and Principe 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 Sao Tome and Principe is 85.6 %.
Aged dependency ratio is a ratio of people above working age (65+) to workforce of a country.
Aged dependency ratio in Sao Tome and Principe is 6.1 %.
