On the Traditional Country in the Type of Population Growth

Nigeria, a country with a traditional population reproduction type.

The types of population reproduction are divided into different types according to the characteristics of population reproduction in different stages of human history. It can be divided into the following three types:

1. The traditional mode of population reproduction adapts to the agricultural economy dominated by manual labor. It is characterized by declining mortality, high birth rate and accelerated natural population growth.

2. The type of modern population reproduction that is compatible with the socialized large-scale production economy based on modern science and technology. Its main characteristics are the reduction of birth rate and death rate, the extension of the average life expectancy of the population and the slow replacement of the times.

3. Transitional types of population reproduction between traditional and modern types.

The emergence of agriculture has promoted the first great development of productive forces in human history. Under the agricultural economic conditions dominated by manual labor, although the productivity level has improved, the living environment such as food supply and medical conditions has improved, and the mortality rate has decreased compared with the primitive society, the mortality rate is still high and fluctuates greatly. Because birth control is not popular now, having more children can provide for the elderly on the one hand and share the work and increase income on the other, so the birth rate is still high and the population growth rate is accelerated. The type of population reproduction in this period is called "traditional type", which is characterized by high birth rate, low mortality rate and high natural growth rate. Before the industrial revolution, most Asian, African and Latin American countries belonged to this type; What is more obvious in today's world is the backward developing countries.

According to the information I searched in the library and online, I think Nigeria is one of the countries with traditional population reproduction types. According to the data calculated from the census conducted in Nigeria in 199 1, the population growth rate in that year was about 2.83%. According to another data, in the 1990s, the average birth rate in Nigeria was 4.0 1% and the death rate was 1.23%. The population growth rate is 2.78. In 2000, the birth rate was 4.2%, the death rate was 1.3%, and the natural growth rate was 2.8%. In addition, according to the statistics of the United Nations Population Fund 200 1, Nigeria's population growth rate was 2.6% in that year, and in 2003, the country's population growth rate dropped to 2.53%. It can be seen that the population reproduction type characterized by high birth rate, low death rate and high natural growth rate belongs to the traditional country. By the end of 2007, the population of Nigeria has reached1.31860 million, which is not only the most populous country in Africa, but also the top ten country in the world. However, it is not difficult to see that from the early 1990s to the 20th century, Nigeria's population growth rate dropped significantly, which, in my opinion, is closely related to the reduction of the country's birth rate and death rate. It is believed that with the improvement of national population policy, people's concept of fertility and medical and health conditions, Nigeria will eventually enter the ranks of countries in transition of population reproduction in the near future.
