What is the reason for Africa s rapid population growth, and what is the largest natural population

First, the population of childbearing age is too large, so the population growth continues to rise.

secondly, contraceptive measures are ineffective and family planning tools are in short supply;

Third, the infant mortality rate is high, and it is believed that the infant survival rate is high only if there are more births;

Fourth, the phenomenon of early marriage is serious, forming a pattern of premature, too frequent, and too many births.

Africa, high birth rate, relatively low mortality rate, high natural growth rate.

Humanity usually goes through three stages of population growth according to the economic level:

High birth rate, high mortality rate, low natural growth rate.

High birth rate, low mortality rate, high natural growth rate.

Low birth rate, low mortality rate, low natural growth rate.

Africa has now basically transitioned from the first stage to the second stage, which is a high birth rate, a low death rate, a high natural growth rate, so the population is growing too fast!

First of all, from an economic point of view, the economic conditions of African countries have improved since independence, and the living standards of their citizens have improved.

The rapid development of medical technology has increased the survival rate of infants.

Relatively backward thinking.

1. The backward the ideology, the poorer the place, the more backward the people's thinking and education.

2. Insufficient contraception.

3. The national policy is not perfect.

The population base is large. Backward thinking.

Africa is the second largest continent in the world with a natural population growth rate.

No. 1 in the world. In the first half of the 20th century, Africa's population increased by about 1 times. In the 35 years of the second half of the period, Africa's population increased by more than one and a half times. Africa's population has grown at an average annual rate over the past 35 years.

for, one percentage point higher than the world level.

Africa has the highest fertility rate in the world. Total fertility rate of women.

It has been at a high level, with a natural population growth rate of 3 per cent.

Africa's mortality and infant mortality rates are 50 per cent higher than the world average, and with advances in medicine, mortality rates will fall further. Even the birth rate of the population.

If it remains unchanged, the natural growth rate will also be high, and the population doubling time will be shorter.

The natural growth rate is modern.

In 1991, the average natural growth rate in the world was 17, excluding all developing countries, including China.

for 23, all significantly more than China. But all developed countries.

It is only 5, and China is more than 2 times, and the gap is still very large.

Not long ago, the 10-year development program of the 90s called for the average annual natural growth rate of the population to be kept within the limit, and if this goal can be achieved, the country's population will not exceed 100 million by the year 2000, and China will enter the ranks of modern countries by that time.

The factors influencing the natural growth of the population are social factors and natural factors. Social factors include: political factors, economic factors, science and technology, medical care, military factors, culture, education, religion, gender ratio, etc., and natural factors include geological, meteorological and climatic factors.

The total population of Africa is 100 million. Slightly lower than the total number of Chinese, the growth rate is around, that is, the population grows by nearly 30 million a year, which is more than that of Taiwan Province.

The population is millions more, and the top 10 countries in terms of fertility are Niger and Somalia.

of Congo, Mali, Benin, Angola.

of Burundi, Nigeria, Gambia and Burkina Faso.

Without exception, all are African countries.

The reason for the large population of AfricaAfrica is politically unstable, its economic development is lagging behind, it is still one of the least developed countries in the world, most of the population lives in rural areas, most of the people are uneducated, the adult literacy rate is less than 20%, the per capita GDP is only 412 US dollars, condoms and oral contraceptives are too expensive for most people, and it is difficult to guarantee, and the harsh natural environment determines the low population carrying capacity here.

As of January 2021, Africa has a population of about 100 million.

The world has a population of 100 million, second only to Asia, ranking second in the world. Africa's population is growing at an average annual rate, well above the 1% in Asia, and sub-Saharan Africa is growing faster than North Africa. The number of people living in poverty is large and is expected to reach 2 billion by 2050.

Africa has the highest birth rate, death rate and growth rate among all continents in the world. The population is extremely uneven, with about 1,000 people per square kilometre along the Nile and deltas. Deserts such as the Sahara, Namib, and Kalahadi and some arid steppes and semi-deserts have less than one person per square kilometer.

There are also large areas of no man's land.

Reasonable capacity of the population

On the basis of the environmental population capacity, scientists have put forward the concept of reasonable population capacity. The so-called reasonable capacity of the population refers to the most suitable number of people in a country or region under the premise of ensuring a healthy standard of living in accordance with a reasonable lifestyle, while not hindering the quality of life of the future population.

Although the reasonable capacity of the population is an ideal "imaginary number" that is difficult to determine the exact value, it is of great significance for the formulation of population strategy and population policy of a region or a country, and then affects the economic and social development strategy of the region. In reality, human society has already experienced demographic problems such as excessive population growth and population aging.

The population problem has further led to serious resource problems and environmental problems. Although the population of developed countries accounts for only one fifth of the world's population, the total amount of resources actually consumed is large, and the geographical areas for which resources are claimed and passed on to harmful production are far beyond the scope of the country. Not only do the vast number of developing countries have large populations and low levels of per capita consumption, but the populations of some countries are still growing rapidly.

If developing countries raise the quality of life per capita to a level comparable to that of developed countries on the basis of their existing economies, the resulting resource shortages and environmental problems will be quite serious and difficult to solve. It can be seen that humanity has a daunting task to eradicate poverty and protect the reasonable capacity of the population in all parts of the world.

About 100 million.

Africa (English: Africa), the full name of Africa, is located in the western part of the eastern hemisphere, south of Europe, west of Asia, east of the Indian Ocean, west of the Atlantic Ocean, across the north and south of the equator, with an area of about 30.2 million square kilometers (land area), accounting for the world's total land area, is the second largest continent in the world.

The African continent has a vast plateau, with plateaus at an altitude of 500-1000 meters accounting for more than 60% of Africa's area, and is known as the "plateau continent". Mountain plateaus above 2,000 altitudes account for about 5% of Africa's area. Plains below 200 metres above sea level are mostly found along the coast, less than 10% of Africa's area.

The average altitude of the African continent is 650 meters.

Africa is one of the birthplaces of ancient humans and ancient civilizations in the world, with the earliest written records dating back to 4000 BC. Egypt in northern Africa is one of the cradles of world civilization.

Reasons for Africa's Rapid Population Growth + With a population of 748 million, Africa is the second most populous continent in the world.

The ethnic question in Africa is complex. Most of the ethnic groups are in a tribal state. With the largest number of tribes in the world, Africa is the largest in the world.

According to some sources, the number of tribes in Africa can reach 3,000, and the most conservative figure is 250, and the reason for this large numerical difference is that some tribes are not very different from each other, and can be divided into multiple tribes or considered as one tribe. Each tribe has its own characteristics, including customs. Generally speaking, each tribe has its own traditional "territory" and can live amicably with each other, or at least peacefully.

However, there are also a few areas where the roots of the contradictions between the tribes are very deep, and the conflicts and fights between them are continuous, sometimes escalating to tribal wars, with tens of thousands of casualties on both sides, sometimes more than one million.

Africa's population growth is the highest in the world. This situation is seriously affecting Africa's social and economic development, and has brought many problems to the ecological environment, food, education, medical and health care, employment, transportation, and social security.

The fertility rate of Africans is the highest in the world, according to statistics, the average fertility rate of African women is 6.5, compared to 4 for women in Latin America, 3 in Asia and 2 in developed countries. The average Kenyan woman has 8 children at birth. ++ In stark contrast to the aging population of developed countries in the West, the population composition of African countries shows a trend of younger age.

According to statistics, children under the age of 15 account for 50 of the total number of people in Africa, and in some countries it is as high as 70, and people over the age of 60 account for only 5 of the total population of Africa. Over the next decade or so, as more women enter childbearing age, Africa will maintain its peak fertility and population growth will remain high.

Blacks account for 16%, yellow people account for 41%, and white people account for 43%, mainly because of the rapid population growth, the high fertility rate of Africans and the negative population growth in Europe and the United States.

Among the three major ethnic groups, the white race has the largest population, followed by the yellow race, and finally the black race. In addition to Europe, North America and Oceania, which are the main distribution areas of white people, South Asia, which has a large population, and Central Asia, West Asia and North Africa, where Islamic countries gather, are also white distribution areas.

The black population is the smallest, mainly in sub-Saharan Africa, while the yellow race is mainly found in eastern and Southeast Asia, and there are also some yellow people in South America.

Over the past few years, it has been evident to many people that the population of blacks is rapidly expanding, for example, more than half of the new births in many French cities are now black, and sub-Saharan Africa is one of the fastest growing regions in the world.
