Analyzing
the parameter at which the population is increasing, every minute 270 children
take birth around the globe, the world’s population to hit 8 billion by 2023. The world’s
population reached a billion at the start of the 19th century. 220
years down the line, the scenario is such the world’s population is racing
closer to 8 billion. It was in the year 2011 when the world population crossed
7 billion.
Since
1990 every year, July, 11th is observed as 'World Population Day.' On
this day across the globe, governments, NGOs, and the designated wings of the
UN-run awareness campaigns and people are involved in the dialogues pertaining
to the rising population.
On this
world population day we will tell you what led the population to grow at such
an alarming rate and 5 major reasons after this:
High
Birth Rate in between 18th-20th centuries:
One of the prime reasons behind this alarming rise in the
population is the increase in Birth Rate. From the 18th till the end
of the 20th century the birth rate was on the rapid rise. Around 250
years ago on average, a woman gave birth to 6 children and this situation
remained for over 150 years. A slight relief in the case came in the year 1950
when the number came down to 5. After 1950 the birth rate gradually fell, but,
meanwhile, the environment of population explosion remained to brew up.
Especially in Asia, where the population increased rapidly in India and China.
The birth rate at present stands at 2.5 children for each woman. Owing to the
situation of high birth rate in the world, the global population reached 100 crores
at the start of the 19th century. It took 123 years for the world
population to reach 200 crores in the years 1927 and 300 crores in 1960. Once
the population crossed 300 crores, every next 100 crores kept on getting added
to the population in two decades.
Increase
in the Life Expectancy:
250
years ago, the average life of humans was 28 years only, which has now
increased to 70 years. If we take a look at the life expectancy scenario, the
average age was just 28, which implies the majority of people died after
attaining the age of 28. It is since the 18th century, that life
expectancy is on the rise. There are 30 such countries where life expectancy is
above 80 years and in 100 countries above 70. In India, this rate stands at
69.7 years.
Gradual
decreasing Death rate:
One of
the prime reasons among others for the huge population rise is the decreasing
Death rate. It was in the year 1950 only when a gradual decrease in the both
Birth and Death rate was observed. The number says that in every 1000 people,
20 died the number in 2020 stands at 8 only. Whereas the birth rate is still
too high in comparison with the death rate.
Lack of
awareness among women regarding contraception:
Earlier
women had a lack of knowledge regarding contraception and methods to avoid
pregnancy, which was one of the most prominent reasons behind the huge birth
rate. If we take the case of the progressive nations in Asia, Latin America,
and Africa, only 9% of the married couple made the use of contraception in
1960. But the scenario changed in by 1990, by this time every second couple
made the use of pregnancy to avoid unwanted pregnancy. Today women are aware of
the usage of contraception. As per the number revealed in 2015 64% of women
were using contraception.
Decreasing
Infant Mortality Rate:
Another
major reason behind the exponential rise in population is the decreasing infant
mortality rate. In the year 1990 where 93 children died among every 1000
newborns the status at present has improved due to medical intervention and the
number in 2020 stands at just 37. However, infant mortality even depends on the
factor where a child is taking birth. Even today in Sub-Saharan Africa in every
1000 infants 79 are dying, whereas the situation in America and Europe is far
better, where the infant mortality rate is 6.
Rapid
population rise and low Birth rate:
The
major question that must ponder is amid the low birth rate how the population
kept on increasing. The reason lies in the fact that the Birth rate tells us
the half story of the population. When we look at the death rate we find that
among every 1000 people the death rate stood at 7.6, whereas on the same number
of people 18 are taking birth. Implying the birth rate is twice what the death
rate is.
India on
the top in population, and China’s population will decrease to half:
Around the globe, today 270 children are taking birth every
single minute, which amounts to 13 crores in a year. The world is racing
towards 8 billion now, the same number is expected to touch 11 billion by 2100.
It is expected that India will become the most populous country in the span of
3-4 years. Whereas a report from the World Economic Forum says that there will
be a huge fall in the population of India and China towards the end of this
century. In the year 2100 India’s population will be at 1.09 billion, China
will slip to the third spot and Nigeria will be the second-most populous country
in the world.
Interesting Facts associated with the world population:
v
The
world’s most populated city is Tokyo with 3.7 crores residents, and New Delhi is in
the second position with 2.9 crores people. Whereas Shanghai is in third place
with 2.6 crore people.
v
New
Zealand has more wolfs than humans, In the year 1982, the population of New
Zealand was 33 Lakh whereas the number of wolfs was 7 crore. That means for
every 1 human New Zealand had 22 wolfs. At present, the country’s population
is 50 Lakhs whereas the number of wolfs has decreased to 2.5 crores. Still, on
every 1 human, there are 6-7 wolfs.

more than 50%.
v
As
per the report from the United Nations, the world population will increase by
2.2 billion in the next 30 years, whereas with 1.2 billion Africa will contribute
to half of it.
