The world population is currently estimated to be 7.442 billion people. While some estimates say the Earth can sustain up to 10 billion people based on food resources, others believe the maximum is lower due to factors like widespread meat consumption. Currently there are slightly more men than women globally, with 101.8 men for every 100 women. China has the largest population of any country at over 1.4 billion people, followed by India. The world's population has grown rapidly over the last 50 years, doubling from 2.5 billion in 1950 to over 6.5 billion in 2005. Estimates for the Earth's carrying capacity range widely from 4 to 16 billion, so views differ on whether human overpopulation has already occurred.
3. How many people can the Earth
sustain?
• So 10 billion people is the uppermost
population limit where food is concerned.
Because it's extremely unlikely that everyone
will agree to stop eating meat, Wilson thinks
the maximum carrying capacity of the Earth
based on food resources will most likely fall
short of 10 billion.Oct 11, 2011
4. How many women are there in this
world?
• More precisely, out of 1,000 people, 504 are
men (50.4%) and 496 are women (49.6%). For
every 100 girls, 107 boys are born, but males
have a higher risk of dying than females, both
in childhood and at adult ages.
5. How many men and how many women
are there in the world?
• Overall, there are slightly
more men than women in the world.
According to 2015 estimates by the United
Nations, there are 101.8 men for every
100 women, with the number of men rising
gradually each year since 1960.Aug 19, 2015
6. How many people are in the world in
2016?
Year Population Yearly % Change
2016 7,432,663,275 1.13 %
2015 7,349,472,099 1.18 %
2010 6,929,725,043 1.23 %
2005 6,519,635,850 1.25 %
World Population (2016 and historical)
7. How many people will be in the world
in 2020?
• 7.442 billion
9. What is the most populated country?
• China has the world's largest population (1.4
billion), followed by India (1.3 billion). The
next most-populous nations – the United
States, Indonesia, Brazil andPakistan –
combined have less than 1 billion people.Jul

10. Why is the world's population growing
so fast?
• This rapid growth increase was mainly caused
by a decreasing death rate (morerapidly than
birth rate), and particularly an increase in
average human age. By 2000
the population counted 6 billion heads,
however, population growth(doubling time)
started to decline after 1965 because of
decreasing birth rates.
11. How many Hindus are there in the
world?
• Hinduism has over 1.15 billion adherents
worldwide (15-16% of world's population)
with the majority living in India and Nepal.
Along with Christianity (31.5%), Islam (23.2%)
and Buddhism (7.1%), Hinduism is one of the
four major religions of the world by
percentage of population.
12. How much has the world's population
increased in the last 50 years?
• For the last 50 years, world population
multiplied more rapidly than ever before, and
more rapidly than it is projected to grow in the
future. In 1950, the world had 2.5
billion people; and in 2005, the world had 6.5
billion people.
13. Is the world overpopulated?
• Most contemporary estimates for the carrying
capacity of the Earth under existing conditions
are between 4 billion and 16 billion.
Depending on which estimate is used,
human overpopulation may or may not have
already occurred. Nevertheless, the rapid
recent increase in human population is
causing some concern.
