Examples Of Overpopulation In Developing Countries

Population is the group of organisms in the same species that live in the same region and can interbreed, an example of this is human population. Humans live in groups depending on their beliefs and cultures, but when there are too many people in one region which cannot sustain that amount of people, overpopulation occurs. Overpopulation occurs when an area cannot sustain its inhabitants. For example, there is not enough food to feed everybody, or there is not enough medical care to support everybody or there is no enough security to protect everybody. That occurs in countries that are less developed. One more developed countries, the majority of the population lives a healthy and sustained life, therefore it is able to survive and develop.

An example of the first stage is Congo, an example of the second stage is Rwanda, and example of the third stage is Peru, and an example of the fourth stage is the United Kingdom. As statistics prove, birth rates are higher on the countries on the first stages, and lower for the countries on the last stages. For example, in Congo the average birth rate is 28 and on Rwanda it is 31, while on Peru it is 20 and in the UK it is 12. This shows that lots of women in the UK have knowledge about family planning. The percentage of contraceptive use is important because it measures how many people have control over child birth. In countries within the first stages, there is less education and use of contraceptives, therefore more child births. In Congo for example 45% of the population uses contraceptives, in Rwanda 52%, in Peru 74% and in the UK 84%. On the other side, death rates are higher on less developed countries because of the shortage of medication and health care. For example, the birth rate on Congo is 10, on Rwanda it is 8, on Peru it is 5 and in the UK it is 9. Adding up, the natural increase of a country is the birth rates minus the death rates which leads to how much the population increases. The life expectancy, which is how long people live, is higher on more developed countries because of the better quality lifestyle, and the country being able to sustain most of its

On the first stages there are more kids because of the lack of knowledge of family planning. In Congo, 42% of the population is under 15, in Rwanda 41%, in Peru 29% and in the UK only 18%. On the other hand, on the last stages there are older people because of the healthier and easier life of the elder on more developed countries. In the UK, 17% of the people is older than 65, on Peru 6%, on Rwanda 3% and Congo 3%. The urban population is the population that lives on more urban areas, such as cities. In countries with more population and development there is a greater number of urban areas, therefore more people living on urban areas. For example, in the UK 80% of its population lives on urban areas, in Peru 75%, in Rwanda only 17%, and in Congo 64%. A person's income, or GNI PPP which stands for Gross National Income per capita at purchasing power parity, depends on where the person works. If it is a high developed country, there is a chance that the person will make more money. For example, in the UK the GNI PPP is $35,760, in Peru it is $11,360, in Rwanda it is $1,430 and in Congo it is
