IF THE WORLD HAD 100 PEOPLE
Then there would be :
(1) Male :female :: 50:50
(1) Male :female :: 50:50
(2) 60
Asians,15 African , 13 American, 11 European
(3) 26 Children , 74 Adults ,(8 above 65)
(4) 83 Literate (7 with college degree)
(5) 22 PC owners & sharers
(6) 77 Home owners
(7) 33 Christians,22 Muslims, 14 Hindu, 7
Buddhists,12 Others , 12 Ethics.
Population
projection 1950-2100(in millions)
(1 ) India will equal
China’s population in 2020.
(2) India keeps
growing till 2050.
(3) China decreases its
population till 2015.
(4) EU will stabilise till
2050.
By 2050 the World would stabilise till
2050 at 10 billion in worst scenario.
URBANISATION
Although world’s 50% population lives in urban areas, it is uneven. Asia and Africa
will witness urbanisation till 2020 & 2030 AD only.
INDIAN POPULATION FACTS
India is the 7th largest
nation by landmass, occupying 2.4% of the worlds land and 2nd largest
by population supporting 17.5% of worlds population.
68.8% population of India is rural(31.1% is urban)
More than 31% of
population is below 25 years of age & more than 50% of population is below
35 years of age , also known as the demographic divident. In 2020 average Indian age will be 32(China-37
, Japan-48)

DEMOGRAPHIC
TRANSITION (DT)
Rate of growth of
world population is decreasing due to global demographic transition (DT)
The transition from
high birth and death rate to low birth and death rate , as a country devlops
from a pre-industrial to a industrial economy.
Thomas Malthus predicted
that , as food production will fall short of population growth and starvation
may result , but 20th century “GREEN REVOLUTION” ensured that
would not occur.
REPLACEMENT FERTILITY
RATE(RFR)
It refers to the no
of children females must reproduce over their reproductive life to produce a
stationary population.
Nature ensures 105
boy for every 100 girl
Therefore each 100
women must give birth to 205 kids to keep population stationary.
RFR = 205/100
=2.05
≈ 2.10
Girls can be aborted,
this will push up RFR in that nation.Young people before 28 years of age may
die due to AIDS, malaria.
The RFR varies from
3.35 to 2.06.
World average as of
now 2.33 Children per women at which growth of population will tend to
zero.This will be called ZPG(Zero Population Growth)
When socities have
poor fertility rates they cannot replace themselves , old people
outgrow the younger ones , leading to severe social imbalance.
Such socities
will go extinct in some time.

CHINA’S ONE
CHILD POLICY
Started in 1980 , the one child policy was
a legal measure introduced to slow down China’s exploiting population .
It everted 20 crore births between 1979-2009 , but many exemptions were
given :
1) Rural families could have 2 child , if 1st was a girl or
disabled.
2) Etheic minorities were exempted.
3) If both children were the only children , they could have two kids.
4) Hong-Kong & Makau were exempted.
5) Foreigners were exempted.
5) Foreigners were exempted.
6) In November 2013 , President Xi Jimping relaxed condition (3) for
even only one parent.
THE 4-2-1 PROBLEM
As the 1st generation
of law enforced only children came of age for becaming parents themselves , one
adult child was required to take care of 4 parents & 2 parents.
THE FUTURE
The rich west is
shrinking irreversibly

POSSIBLE 2050 & 2100
(1) In developed nations ,
urban population will be constantly increasing.
(2) Developed nations , rural population will be
constantly decreasing.
(3) Less developed nations , urban population
will be constantly increasing.
(4) Less developed nations , rural population
will increase till 2020 & then decline.
So tighten your seat belts for the huge explosion of the population which
is going to come till 2050. Surely which would effect our economy and we would
need a good political system to manage it.The another key factor would be the
extinction of the natural resources.Therefore need to handle them carefully and
also look after the upcoming generations , so that they could also enjoy the
resources.
Lets take a oath to
look after the natural resources for the benefit of the future generation.
