A Brief History of World Population: There are so many people in this world that you have to care about the population problem.

It is recorded in the Bible that after God created man, he promised Abraham that his descendants would be like the stars in the sky and the sand by the sea. Looking at the whole human development, if the population is counted, it is really as many as stars.

the current population situation is also a problem that we have to care about. Therefore, it is necessary to clearly understand the history of population development.

With A Brief History of World Population, we can explore the population development together and be a new youth who cares about the world. After all, there are so many people in the world, and it is very lucky to meet them.

If you get this book and read it in the library, it will definitely give people the feeling of being a scholar. Take a look at the cover and you will understand.

The black-and-white color scheme shows its advanced level, and the author is also quite powerful: Massimo Levy-Bach, professor of demography at the University of Florence, Italy, and former president of the International Union for Population Science Research. Long-term study of contemporary demography and population history, attention to the population development of countries around the world and prediction of population trends. He has taught at Princeton University, University of California, Berkeley, France College and many other world famous schools, and has written many books and influential papers in the field of demography.

based on the history of human development, the author leads us to discover the truth of fertility and the law of population change, analyzes the world population pattern, and predicts the future population

1. Exploring the truth of fertility

As of April 13th, 222, the total population of 238 countries in the world was 7,898,236,143, of which China had 1,447,31,443. 43,18,576 people rank second on earth, and the third to tenth places are: the United States, Indonesia, Pakistan, Nigeria, Brazil, Bangladesh, Russia and Mexico.

do you have any questions about this figure? Why is the world population 7.5 billion instead of 1 billion, 1 billion or 5 billion, 1 billion? What is the impact on the development of population?

We can roughly determine that the population growth is the function of binding force and selective force. Binding force includes climate, disease, land, energy, food, space and settlement mode. These forces are interdependent, but they have an important impact on population changes.

For example, the mode of human settlement depends on geographical space, so does the availability of land. Food, raw materials and energy all come from land, and they are all important determinants of human survival. The climate determines that the fertility of soil restricts human settlement and is related to the disease pattern, that is, the combination is related to nutrition, which directly affects fertility and living space, and the living pattern is related to population density and the ability to spread diseases. These points have made it clear. When it is linked with population growth, the interweaving of all kinds of constraint forces is very complicated.

Second, the impact of the world population on the economy

I remember seeing many slogans when I was a child, such as:

"You are rich, I am rich, everyone is rich, and family planning will help."

"To get rich, strive to be a family planning household; Run towards a well-off society, and eugenics are guaranteed "

" If you want to have fewer children, plant more trees, and pave the way for more children. "

As a generation affected by family planning, it seems that fertility is directly linked to the economy.

what is the direct impact of population on economy?

let's take Europe as an example, the population expansion before the first world war, the population stagnation between the two world wars, and the strong population recovery since the 196s.

The main demographic factors can be analyzed by reference:

1. The first factor is the geographical-demographic structure of the European continent and its influence on political-economic organizations, which is indirectly related to the advantages and disadvantages of scale.

2. The development of urban areas also determines the role of population growth in expanding demand, especially the rise of big cities, which are often catalysts for development.

3. Mobility and migration measure the ability of the population-economy system to allocate human resources effectively.

It can be seen that the population growth rate is inseparable from GDP.

Third, the future trend of population

Knowing the situation of fertility development and the influence of the world population on the economy, what is the future trend of population development?

don't think these have little to do with ordinary people. As long as I have food, drink and money to spend, I can't.

It's your own business to have children. You can choose to have a "football team", and I can also choose "Dink".

But when we know the future of the population, we won't feel that these things are irrelevant.

The book says: The United Nations boldly predicted the population situation at the end of the 21st century. The world population will reach 1 billion in 256 and 11.2 billion in 21.

how will the appearance of this number affect the future?
