Seven billion people and counting
Did you know that the world's
population is about to hit 7 billion?
It took until 1804 before the world’s population hit its first billion, but the time it has taken to reach subsequent billions has sped up considerably as you can see below.
- 450 million in 1500
- 1 billion in 1804
- 2 billion in 1927 (123 years later)
- 3 billion in 1960 (33 years later)
- 4 billion in 1974 (14 years later)
- 5 billion in 1987 (13 years later)
- 6 billion in 1999 (12 years later)
- 7 billion in 2011 (12 years later)
According to the United Nations, the world's population will hit 9.2 billion by 2050. However the rate of growth has slowed and currently growing at a rate of around 1.15 % per year. Growth has slowed in recent years due to increased family planning in third world countries (reducing the number of children being born), higher education of women and improvements to health and immunisation resulting in babies surviving and people are living longer. However according to the United Nations, fertility is not declining as rapidly as expected in some poor countries and has shown a slight increase in some wealthier countries. The US is growing faster than many rich countries, largely due to high immigration and higher fertility among Hispanic immigrants.
Growth in Africa remains so high that the population there could more than triple in this century, from 1 billion at present to 3.6 billion. This is of concern as Africa is a troubled continent that often has difficulties feeding its people.
Top 10 countries by population size:
- China 1 336 718 015
- India 1 189 172 906
- United States 313 232 044
- Indonesia 245 613 043
- Brazil 203 429 773

- Bangladesh 158 570 535
- Nigeria 155 215 573
- Russia 138 739 892
- Japan 126 475 664
Heres a question to ponder . . . should the worlds population continue to grow at its current rate?
