World Population Growth over past 250 years
In an overview, the global population has boomed over the past 250 years, with life expectancy getting higher in most countries.
According to humupd.oxfordjournals.org, for the past 250 years, that was when the population growth started to really accelerate. It started of by about a billion people during the 1800's, then rose to 1.7 billion people by 1900. This was because life was enhanced; the way of living was improved.
These are due to factors such as...
LEDCs are countries that are poorer or less economically developed such as Somalia, Malawi, Bangladesh, and the Philippines. LEDCs usually have a high birth rate, which means that lots of young people are born, a youthful population, but not a lot reach the age of 75+. This is because of the lack of health care. Also, poorer countries have a higher birth rate than richer countries because they are simply not educated about it. They do not have jobs, insufficient knowledge, and no money.
MEDCs are countries that are richer or more economically developed such as Spain, Germany, and Korea. MEDCs tend to have low birthrate, but most of their population are people who are old. This is because most of the people work and they are educated, not a lot of them want to have children because they have jobs. Richer countries tend to have less kids.
The image shows how the world population has changed over the last 160 years, and how it will grow in the future.
As you can see, the fertility rate in LEDCs are much higher. As discussed in class, this may be because populations in LEDCs:
- Have less access to contraceptives.
- Give less value to women and their rights.
- Have less career oriented women.
- Are not educated about the economic consequences of too many kids.
In this video, it shows the replacement rate of the more developed countries and how their population does not go in a trend similar to less developed countries.
