World
Population:
Some Facts
 The
world population was 6.30 billion in 2003,
according to the United Nations Population
Fund. It is projected to grow to 8.91
billion by 2050. Four out of every five
people in the world live in the developing
world. By 2050, the developing world will
have 88% of the world's population, up from
the present 81%.
The developed
world has reached a stage where the number
of births equal to the number of deaths.
This gives a negligible population growth
rate of 0.2% and a stable population in
terms of numbers. The developing countries,
on the other hand, are estimated to be
growing at the rate of 1.5% per year.

Population Growth, in Billion
World
population is projected to cross the 7 billion
mark in 2013; the 8 billion mark in 2028;
the 9 billion mark in 2054.
-
It has taken just 12 years for the world
to add this most recent billion people
(6 billion). This is the shortest period
of time in world history for a billion
people to be added.
-
World population did not reach one billion
until 1804. It took 123 years to reach
2 billion in 1927, 33 years to reach 3
billion in 1960, 14 years to reach 4 billion
in 1974 and 13 years to reach 5 billion
in 1987.
-
World population nearly stabilizes at
just above 10 billion after 2200.

Population
Growth in More and Less Developed Countries
-
The
increase in world population growth is
mainly contributed by less developed regions
which include majority of Asian, African
and Latin American countries and most
of this growth is taking place in the
urban areas of these countries.
- By
2050, nearly 90 percent of the world’s
population will be living in less developed
nations
-
Today, six countries account for half of
the world’s annual growth of 77 million:
India, China, Pakistan, Nigeria,
Bangladesh and Indonesia. India alone
accounts for about a fifth of the world’s
total population growth.

Women of Childbearing Age (15-49), World
Scenario
-
The number of women of childbearing age
more than doubled between 1950 and 1990:
from 620 million to over 1.3 billion.
-
Their numbers are expected to reach over 2
billion by the middle of this century,
according to the UN.
-
The growing population of women in their
childbearing years and their male partners
will contribute to the future world
population growth, even if levels of
childbearing continue to decline.
