World Population Day

The world's population is growing more slowly due to declining fertility rates

In the last 100 years, the world has moved from a state of high fertility and mortality to a state of low mortality, followed by low fertility rates. In this way, the world's population is expected to stop growing and stabilize at around 11 billion by 2100.

The United Nations (UN) proclaimed 11 July the World Population Day in 1989, i.e. two years after the world’s population exceeded five billion. This day aims to enhance people’s awareness of population issues, including their relations to the environment and development.

At the end of 1950, there were 2.5 billion people on Earth, and by today, there are 7.7 billion of us. By the end of the century, the UN predicts the world population will reach 11.2 billion.

According to UN estimates, every minute around 272 children are born and 113 people die. In 2020 the population of Earth will increase by about 77 million.


The median age of the world's population increases by almost 1 year every 5 years

The median age of the world’s population is 30.5 years, meaning that half of the population is older than 30.5 years and half is younger. This is 9 years more than in 1970, when the median age was 21.5 years.

The population is the youngest in Africa, where the median age is 19.7 years, and the oldest in Europe, where it is 42.5 years. The median age in Slovenia is 44.5 years, which places it in the 10th place in the world.

Through the changes shown from 1950 to the present and projections until 2100, we can see that the global population pyramid is becoming wider in the upper part and is shaped more and more like a box, which is a result of ever longer average life expectancy, lower child mortality, and lower fertility rates.


Fertility rates worldwide are declining

Total fertility rate - the average number of live-births per woman is a key variable that affects the development of the world's population. UN figures show that in 1966, the global total fertility rate was still 5 children per woman. Since then, it has halved and is now below 2.5 children per woman. The UN predicts that the global fertility rate will decline to 2.08 by 2070 and fall below 2 by the end of the century, which would then mean a long-term decline in the world's population.

In Europe, which is now the continent with the lowest fertility rate, the rate fell to 1.43 children per woman at the end of the last millennium, but has risen slightly in recent years (currently 1.61) and is expected to stabilize by 2100, according to UN forecasts at around 1.77.

On the other hand, Africa, with 4.44 children per woman, is the continent with the highest fertility rate, but also there, since the early 1980s, it has been falling rapidly. For the end of the 21st century, the UN predicts a decline in total fertility rates in Africa to around 2.14 children per woman.

Slovenia

In Slovenia, the total fertility rate was decreasing until 2003, at which point it was only 1.20 children per woman, but has since then risen slowly to 1.61 last year.

Slovenia’s population is less than 0.03% of the world’s population. In the past 50 years Slovenia’s population grew by about 370,000 or a little more than a fifth and in the past ten years, it grew by about 50,000.

According to the EUROPOP2019 projections, the population of Slovenia is expected to increase until approximately 2024, when it is expected to be 2,116,000, and then start to slowly decrease. In 2060, Slovenia is expected to have fewer than 2 million inhabitants.
