The world's popularity is not growing as a result of babies, but the elderly. More and more of us are living longer.

The world's popularity is not growing as a result of babies, but the elderly. More and more of us are living longer.

The world's population increased wildly throughout the 1900's. In the year 2011 our population topped 7 billion, a billion of which was gained between 1999 – 2011. No wonder we talk about an explosion of population.

Population growth is often related to birthrate. Still, birthrate is actually decreasing almost everywhere in the world. According to the UN, in 2010 2.4 babies were born per women, while in 1990 it was 3. What has actually been increasing the population for decades is the increasing amount of elderly people, rather than newborns. More and more of us will be wrinkly and grey haired.
 

Life expectancy is based on the present, not the future

China is the world´s most populated country. Still, only 1.4 are born per woman in China. The doubling of people's age in just over 50 years is the reason for China's population. In 1950, Chinese life expectation was 39.2 years, by 2011 it had gone up to 76 years. The situation is the same almost everywhere in the world.

We are living longer than what current life expectancy is reporting.The increase of the average age may continue well into the future. There have been guesses that one in five of the women born in 1975 will live to be at least 100 years old. However, even though life expectancy has continued to grow in industrialised countries, currently a human´s maximum age is about 120 years.

It is estimated that in 2040 the planet will carry 9 billion people. Population will start to decrease in the next 70 years, but until then population is continuing to grow because medical science is improving and cures are spreading to developing countries as well.

So, while speculating on the world's future, one can’t keep blaming newborns anymore. Instead, if we are going to live longer, we should pay more attention to how we live.
 

Push: In Europe, life expectancy has increased by 20 years in the last 60 years

Social media push: Population growth is being caused by the elderly, not newborns. The good news is, more and more of us will be wrinkly and grey haired #population
