United Nations: The world population is
set to touch the 10 billion mark at the dawn of the next
century, with the bulk of this increase coming from "high
fertility" countries of Africa and Asia, a UN report said
on Wednesday.

According to figures released today by the United
Nations, the world population will reach 9.3 billion by the
middle of this century and 10.1 billion by 2100.

India, which is an intermediate fertility country,
will see its population peak at 1.7 billion by 2060. China,
which is a low fertility country, will see its population peak
at 1.4 billion by 2030.

The bulk of the increase will come from "high
fertility" countries, which comprise 39 countries in Africa,
nine in Asia, six in Oceania and four in Latin America.

High fertility countries will see population growths
till the end of the century.

"The future of the population depends very much on
what will happen to the future of fertility in the world,"
Hania Zlotnik, Director, Population Division, Department of
Economic and Social Affairs (DESA), told journalists.
"Towards the end of the century low-fertility
countries will have a relatively aged population," she said.
"The intermediate fertility countries get more or less
to the same point".

Pakistan, Nigeria, the Philippines, Ethiopia, the
Democratic Republic of the Congo, the United Republic of
Tanzania, Sudan, Kenya, Uganda, Iraq, Afghanistan, Ghana,
Yemen, Mozambique and Madagascar account for 75 per cent of
the population of high-fertility countries.

The report said that between 2011 and 2100 populations
in high fertility countries would more than triple, passing
from 1.2 billion to 4.2 billion.

During the same period, the population of the
intermediate-fertility countries would increase by 26 per
cent, from 2.8 billion to 3.5 billion, while that of the
low-fertility countries would decline by about 20 per cent,
from 2.9 billion to 2.4 billion.=
The world population is expected to reach 7 billion
towards the end of this year.

"What is astounding is that the last two billions have
been reached in record time... The population has been adding
new billions every 12 years in the last 25 years," Zlotnik
told journalists.

"The world hasn`t collapsed by adding so many people
but what is important is that most of these people are being
added in the poorest countries in the world," she said.

The UN official said that if these countries would
face "serious problems" in the absence of reduced fertility
rates.

Zlotnik said that producing and distributing food for
9.3 billion by the middle of the century were serious
challenges.
