  In the time it takes you to read this sentence, the population of the world will have grown by ten people.That may not sound much, but it is 9,000 people in an hour, 1.5 million a week, or 79 million a year.That is the same as adding most of the population of Germany to the world every year.

  Most of these new people were born in developing countries.These countries are found in much of Africa, South America and parts of Asia.In the developed countries of Europe and North America, the population is growing very slowly.This is because women in these countries have, on average, only one or two children.In the developing countries, many women have five or more children.In 1950, around one quarter of the world's population lived in the developed countries.By 2050, these countries will be home to only around one tenth of the world's people.

  In the developing countries, more than one billion people already live below the poverty(贫困)line.These people do not have enough food to eat and they live in poor housing; children get little or no time at school and people suffer(遭受痛苦)from many kinds of diseases.

  At the beginning of the 21st century, the world's population was around six billion people.The UN has said that the world's population will level off at 12.5 billion people by the year 2100.Other groups think the world's population will continue to grow, reaching 14 billion people before it becomes stable(稳定的), or even falls.
