How many people are there in the world so far?

According to the latest statistics released by the United Nations, the world population will exceed 7 billion this month, and the 7 billionth resident may be born in the Asia-Pacific region.

199910 June 12 At 0: 02 am, a baby boy was born in Sarajevo, the capital of Bosnia and Herzegovina, which was the 6 billionth person.

Annan (first from right), then Secretary-General of the United Nations, also made a special trip to the hospital to visit the baby boy.

It is estimated that the 7 billionth person will be born in the Asia-Pacific region, and it will break through the 654.38+00 billion mark by the end of this century.

Population experts pointed out that the total population of the world increased by 65.438+0 billion only in 654.38+02 years.

According to the forecast, the world population will exceed 8 billion in 2025 and reach 654.38+0 billion by the end of this century.

The United Nations report pointed out: "By the middle of this century, the world population will increase by 2 billion, and most of them will be born in poverty-stricken areas, which will make hunger, poverty and environmental problems more serious. If the growth rate cannot be controlled, the earth's natural ecosystem will collapse and mankind will face extinction. "

The resource problem is getting more and more serious.

It is reported that since 1940, the world population has tripled, and now the population surge again will pose an increasing threat to mankind and make the global resources face unprecedented tension.

Because of the population explosion and crisis, more people will enjoy the limited resources of the earth, and the poor who rely on natural resources will suffer more because they cannot compete with the rich.

In recent years, the population growth rate of industrial countries has become increasingly stable, but the population growth rate of developing countries has increased, and it is expected to become the "main force" of global population growth in the near future. In Africa and India, overpopulation is even worse.

With the increase of population, the land and water allocated to everyone will decrease, and the problems of pension and medical insurance will become more serious.

Poor people who depend on natural resources will suffer more because they can't compete with the rich. In Britain, people think that "7 billion population day" is a sign that the scarcity of earth resources is further aggravated.

DavidBloom, a professor of economics and demography at Harvard University, said: "Many developing countries will struggle in food, housing and energy supply, and population growth will affect health, safety and economy. However, this is not insurmountable. We must publicize contraceptive knowledge and reform retirement policies and immigration measures. "

In a world of 7 billion people, nearly 1 100 million people are starving.

According to the latest statistics released by the United Nations, the world population will exceed 7 billion this month.

However, nearly 654.38 billion people in the world still suffer from hunger for a long time.

According to the statistics of FAO and WFP, the number of people suffering from chronic hunger in the world in 20 10 is estimated to be 925 million. As FAO is revising the calculation method of the incidence of hunger, the estimated data of the world's chronically hungry population in 20 1 1 year has not been published.

How to determine the 7 billionth person? According to statistics, four new lives are born every second in the world.

According to this calculation, tens of thousands of new lives will be born every hour. On what basis does the United Nations determine the identity of the 7 billionth person who is born all the time?

In fact, the 7 billionth person was appointed by the United Nations itself. According to the demographic data and population growth rate submitted by various countries, the United Nations Population Division has calculated that the world population will reach 7 billion in 20 1 1 and 1 year.

After that, the United Nations will choose the baby that is most likely to be born at zero on that day as the 7 billionth person in the world. In other words, the 7 billionth person is a symbolic name.

In 2033, the population of China reached 65.438+0.5 billion.

The population of China increased from 500 million in the early days of the founding of the People's Republic to 700 million in 1964, and it takes seven and a half years for each population to increase100000. From 1964 to 1974, the population of China increased rapidly, from 700 million to 900 million, and it took only five years to increase the population of 1 100 million.

Since the reform and opening up 20 years ago, with the implementation of the family planning policy, the time required for each population increase of 654.38 billion+0 billion has been extended to more than 7 years. 198 1 year, the population of China reached 1 billion, 1988 exceeded10/billion, 1995 exceeded1200 million,/kloc.

On June 6th, 2005, the population of China reached 654.38+300 million.

According to the forecast of relevant departments, the population of China will reach 654.38+0.4 billion in 2065 and 654.38+0.4 billion in 2020. The peak of the total population will appear around 2033, and the total population will reach about 654.38+0.5 billion.

India's population will continue to climb. In the past 10 years, the total population of India has increased by 17.6%, reaching 12 1 billion. It is predicted that in 2025, India will surpass China and become the most populous country in the world.
