A baby born in India has been declared the world's seven billionth person by child rights group
Plan International. Baby Nargis was born at 07:25 local time(01:55GMT)in Mall village in India's
Uttar Pradesh state. Plan International says Nargis has been chosen symbolically as it is not possible
to know where exactly the seven billionth baby is born. In addition to baby Nargis in India,Bangladesh,
the Philippines and Cambodia have all identified seven billionth babies. The United Nations estimated
that on Monday 31 October. the world's population would reach seven billion.
Populations are growing faster than economies in many poor countries in Africa and some in Asia.
At the same time,low birth rates in Japan and many European nations have raised concerns about labor
shortages.
Population experts at the United Nations estimated that the world reached six billion in October
1999. They predict nine billion by 2050 and ten billion by the end of the century. China's population
of one and a third billion is currently the world's largest. India is second at 1. 2 billion. But India is
expected to pass China and reach one and a half billion people around 2025.
India will also have one of the world's youngest populations. Economists say this is a chance for a
so-called. demographic dividend. India could gain from the skills of young people in a growing economy
at a time when other countries have aging populations. But economists say current rates of growth,
although high,may not create enough jobs. Also,the public education system is failing to meet demand
and schooling is often of poor quality. Another concern is health care. Nearly half of India's children
under the age of five are malnourished(营养不良).
Michal Rutkowski,the director of human development in South Asia at the World Bank, says reaching
seven billion people in the world is a good time for a call to action. He says,"I think the bottom line of
the story is that the public policy needs to become really,really serious about sex equality and about
access to services-to fight against malnutrition,and to provide for access to health services,water and
schooling. "
