Most new people were born in developing countries. These countries are found in much of Africa,South America and some parts of Asia. In the developed countries of Europe and North America,the population is growing slowly. This is because women in the countries have,on average (平均),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 counties more than one billion people are still living below the poverty(贫困) line. These people do not have enough food to eat and they live in poor houses. Children get little 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. The UN(联合国)has said that the world's population will continue to grow,reaching 14 billion before it becomes stable(稳定的),or even falls.

“Many people died in their thirties or forties when I was a child", Chen Zhixiang, an 82-year-old teacher who grew up in Xi'an, told Xinhua. At that time, living to be 60 was a long life.

But that is no longer the case. According to the National Bureau of statistics(国家统计局), the life expectancy for Chinese people rose from 35 in 1949 to 77 in 2019.

Chen told Xinhua that he rarely ate meat when he was a child. People didn't have enough food and clothing at that time. And anyone who became ill may die.

Now Chinese people are enjoying healthier and more nutritious diets. The grain, meat, peanut and fruit has topped the world for many years, according to the State Council. In 1949, China's per capita disposable income(人均可支配收入)was 49.7 Yuan. This same income reached 28,228 Yuan in 2019. It refers to the amount of money that each person has for spending and saving after paying taxes.

China is also paying more attention to improving people's health. China's medical insurance system covers more than 95 percent of the people.

The country has also made efforts to keep its people healthy with a national health program. As of 2019, China had more than 3.2 million sports venues across the country. Over 400 million people take part in daily exercise.
