World Population Growth over past 250 yearsThis is a featured page

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...

  • Better Sanitation
  • Better Health Care
  • Urbanization
  • Easier access to clean food, water, etc.

Although most countries in the world are constantly growing, some are outpacing others. For example: LEDCs are growing at a much faster rate than MEDCs.

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.




World population growth

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.




The Effects of Population Growth on the Planet



Overpopulation is becoming a major concern on earth. One of the main reasons are the scarcity of resources, especially in the future as the population growth becomes more hasty, thus the planet struggles to cope with the growing demand of commodities. Additionally to the growing supply and demand, its distribution is not always balanced around the populace, leading to the increase of poverty in a country.This also may be a factor why countries with a higher population are generally not as economically sound. In addition, it is believed that for us humans to survive, we need three planets! We only have one, Earth. If the population continues to grow at this rate, we will face the deadliest challenge humans will ever face--starvation.
