1.       Summary

Demography is the study of the size, structure, and distribution of the population and how the population changes over time due to birth, death, migration, and aging. Demographic statistics rely primarily on large datasets derived from registration statistics (birth, death, and marriage registration). This large data set is necessary to monitor trends in demographic indicators such as birth and death rates. Because demographers are interested in changing the human population, they focus on specific indicators of change. One of the examples of this study is fertility and reproduction. infertility refers to the ability of females to produce healthy offspring in demographics, and fertility refers to the potential reproductive ability of women. On this topic, demographics provide a diagram showing the world's trends in birth season and the various birthrates of certain countries. In addition, there are demographic changes, which are models and theories that describe the transformation of low birth and mortality, high birth and mortality that occur as part of the nation's economic development.

2.        What is interesting / what did you learn

What was interesting about this article was the demographic portion as a function of food availability. Some scholars say that the amount of food people can eat will grow and shrink as expected. This means that food production responds to population growth each time it increases to feed the growing population. Historically, some human populations back up this theory as a consistent population began to grow due to the ever-increasing agricultural revolution in food supply. However, critics point out that the birthrate is the lowest in the developed world and that access to food is the highest. In fact, in some countries where food supplies are abundant, the population is decreasing. Therefore, the human population does not always grow in accordance with the amount of food available.

3.       Discussion point

So, why do you think the birth rate of developing countries is higher than that of developed countries?
