Summary:

Demography is a study of population size, distribution, and change patterns.

Demographics are essential to explain social phenomena.

Research on the population occurred with the scientific and industrial revolutions.

Demography has also been established for political purposes, such as as a basis for taxation and as a basis for political representation.

Demographics use large amounts of data.

Demographers focus on how certain indicators such as fertility and mortality change.

In demography, fertility rates use Fertility and Fecundity.

In demography, mortality is much concerned with the place and time of death, and the proportion of deaths relative to population.

Population growth occurs mostly in less developed countries and overpopulation means that the population is growing beyond the range that the region can accommodate.

Thomas Malthus argued that if we do not limit our population, we will have a population that we can not afford.

There are scholars who argue that population changes depending on food availability.

The overpopulation brings about various negative effects such as Child poverty, High birth rates, Lower life expectancies and Lower levels of literacy.

To overcome the overpopulation, there is a way for the economy to develop and a way to control the population.

In order to solve the underpopulation, a country with a low fertility rate may implement a birth promotion policy.

Migration differs depending on the area where you reside.

Urbanization is a phenomenon of urban population growth.

The reason people move to the city is to get economic advantage and to use various services.

Urbanization can lead to economic growth, but it can also cause environmental problems such as heat island.

Opinion:

Through this data, I was able to see how demographics are used and how statistics are going.

I also did not know much about the negative phenomena caused by overpopulation.

However, I learned more about them through this material.

Question:

What are the negative effects that urbanization brings in addition to what is shown in these data?
