A brief history of Chinese immigrants in Mexico

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 large, it is really as many as stars.

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

Through a brief history of world population, we can discuss population development together and be a new youth who cares about the world. After all, there are so many people in the world that we are lucky to meet them.

If you get this book, if you read it in the library, you will definitely feel like a scholar. Look at the cover and you will understand.

Black and white color matching shows its advanced nature, and the author is also quite powerful: Massimo Levy-Bach, a 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, paying attention to the population development and population trend prediction of all countries in the world. 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.

Starting from the history of human development, the author leads us to discover the truth of fertility and the law of population change, analyze the world population pattern and predict the population future.

First of all, explore the truth of fertility.

By April 3, 2022, the total population of 238 countries in the world is 789,823143, among which China ranks first with 1.44730 1.400, making it the most populous country in the world, and India has 65,438.

Do you have any questions about this figure? Why is the world population 7.5 billion instead of 10 billion, 10 billion or 5 billion, 10 billion? What is the impact on population development?

We can generally determine that the growth of population is a function of binding force and selectivity. 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, which are important determinants of human survival. Climate determines that soil fertility restricts human settlement, which is related to disease pattern, that is, combination is related to nutrition, which directly affects fertility and living space, and living pattern is related to population density and disease transmission ability. These points have been made very clear. When it is linked to population growth, the interweaving of various binding 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 have money, I have money, and everyone has money to help with family planning."

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

"If you want to be rich and have fewer children, you should plant a variety of trees to pave the way for being rich and having fewer children."

As a generation influenced 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 expanded before the First World War, stagnated between the two world wars, and recovered strongly since the 1960s.

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 the political-economic organization, which is indirectly related to the quality of the 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 population development trend?

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

Whether you have children or not is your own business. You can choose to have a "football team" or I can choose "Dink".

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

The book says: The United Nations boldly predicted the population situation at the end of 2 1 century. In 2056, the world population will reach 10 billion, and 210/200 million in 2000.

How will the appearance of this number affect the future?
