---------------------------- Graph explanation: ---------------------------- In the year 1800, the world population is 0,9 billion which means the populations has an annual growth of 0,4% since the year 1750, in just a few years, the global human population would reach its first billion. In a hundred years, the population increases by 0,75 billion, making the population in the year 1900 1,65 billion people, a 0,55% increase in a hundred years.
Less than a century after, in the year 1960, the population almost doubles from 1,65 to 3,0 billion, an increase of 1,35 billion; this immense growth is attributed to the advancements of medicine, a booming global economy, and the advancements of the quality of human life, in this period, humanity grows at a figure of 1,8% annually.
Twenty years after at the year 1980, the population grew 1,4 billion from 3,0 to 4,4 billion. In just twenty years. Some statistician and scientists attribute this immense growth to post-war optimism, exponential technological advancement and the advancements of nuclear energy during the Cold War period, which happens in First and Second World countries such as Western Europe, North America, East Asia and the Soviet Union.
The largest population growth happens between the year 1960-1980, a time when humanity saw a 2,1% annual population growth, the highest number ever achieved by the human race since the dawn of humanity in the Holocene Era.
Twenty-five years has passed since the year 1980 and it is now the year 2015, in this small timespan of a quarter of a century, humanity breached the five billion mark and the population increases from 4,4 to 7,4 billion, which means the population almost doubles with an immense increase of 3,0 billion (≈70% increase). Though the population almost doubles, annual growth rate falls significantly from 2,1% in the 1960s to 1,8% in mid 1980s and fell further to a comparatively tiny 1,2% in the year 2015.
Ironically, the scientific advancement attributed to the gigantic annual growth during the Cold War is now the reason why the annual growth falls. With increasing lifespans (humans are predicted to live ≥125 years old in the end of the 21st century), an explosive economy, woman emancipation, an increasingly educated (though lazy) population, scientific advancement, family planning, and better quality of life, parents no longer see the benefit of having too much children, most see it as a burden.
Starting from 2015, the United Nations Organization (UNO) predicted that humanity will reach the number 9,2 billion in the year 2040; 10,2 billion in the year 2060; 10,8 billion in the year 2080; and 11,2 billion in the year 2100. Humanity won't have the chance to double their population and humanity is barely able to touch the 10 billion mark by the end of the 21st century. The UNO also predicted that annual population growth would fall to 0,1% by the end of the century.
