The Global Population

Predicting the Future

How fast is the world’s population increasing? What are the components of the increase?

The world’s population is increasing at a rate of 1.2% annually. That is 214,000 people being born every day! Some components of the increase include: improved health conditions and advanced medical technology for people in many countries, high fertility rates, high life expectancy, improvements in child mortality, availability of clean water, and increased food production.

Population Milestones















When did the global population change?












The overall pattern of global population growth: there was a steady increase in global population until 1950 when the population started to increase very rapidly. After that, the population kept increasing, and experts predict that it will continue to grow even more so that by 2150, the global population will reach 10 billion people.

The contribution the ‘less developed countries’ make to global population growth: it is clear there is an unequal distribution of the global population. As it was said in the video and is shown in this graph, the poorest, least developed countries of the world have the highest populations. One reason for this could be high fertility rates: in developed nations, the average woman has 1.5 children. In developing nations, that number is 5.

The contribution the ‘more developed countries’ make to global population growth: the world’s more developed countries contribute much less to global population growth compared to the less developed countries. As the video said, even though people in these countries have high life expectancy, they do not have as many children and so do not contribute to the population growth as much as developing countries.













The world’s population is not growing in a uniform way. Some regions of the world are contributing more to Global Population Growth. How has the global distribution of population changed since 1800?

There has not been a massive change in the global distribution of population since 1800. Asia has always had, still does, and will have in the future, the highest population out of all the continents. Asia has the world’s most populated countries such as China with 1.5 billion and India with 1.2 billion. Oceania is the least populated, and it is predicted that it will stay this way. Also it is interesting how Europe and Asia are predicted to decrease in population by 2050, and all other continents Oceania, Africa, North America, and Latin America are predicted to increase in population.

The population explosion

Brainstorm the reasons for the timing and occurrence of the ‘global population explosion’. 

The global population has been increasing for a long time. In 1800, the world’s population was 1 billion, and now it has reached 7 billion. As I wrote in the first section, the huge increase is because of improved conditions in countries. Compared to the 1800s, medical technology has advanced greatly, and people are living much longer. This also results in improvements in child mortality. Also, right now, there is much more clean water available for the human population, and food production has increased as well. Because of these factors, the global population has now increased to such a high number.
