  1. WORLD POPULATIONGROWTH

  2. 2,000 years ago......at the beginning of the first millennium AD the world's population was around 300 million people.

  3. 1,000 years later (in 1000 AD)......population rose by only 10 million (310 million).Well into the 2nd millennium, it grew less than 0.1% a year.(It wasn’t until the late 1700s that the Industrial Revolution raised living standards & spurred growth.)

  4. 800 years later (in 1800 AD)......population had climbed to the level of 1 billion.Almost 65% of all people lived in Asia. 21% lived in a prospering Europe. Less than 1% lived in North America.

  5. 127 years later (in 1927)......the 2-billionth baby was born. From 1920 to 1950, the growth rate was around 1% a year. Beginning in the middle of the 1900s, antibiotics & health advances profoundly altered life expectancy.

  6. 33 years later (in 1960)......advances in medicine, agriculture & sanitation had spread to the developing world. By 1960, global population reached three billion. In the late ‘60s the growth rate hit 2.04% a year.

  7. 14 years later (in 1974)......new reproductive technologies curbed growth rates.But with so many people already living, a population explosion had begun, centered in the developing world.The four-billionth baby was born in 1974.

  8. 13 years later (in 1987)......the five-billionth baby was born.

  9. 12 years later (in 1999)......the six-billionth baby arrived, and12 years after that (2011)…the seven-billionth baby.Europe & Africa have 12% each of world’s population.Latin America has 9%, with 5% in North America.Asia still has the most - 61%, over 3.5 billion people!

  10. It took…. …from man’s beginnings to 1800 to reach the 1st billion.…127 years to reach the 2nd billion.…33 years to reach the 3rd billion.…14 years to reach the 4th billion.…13 years to reach the 5th billion.…12 years to reach the 6th billion. …12 more years to reach the 7th billion.

  11. World Population Growth Over 2,000 Years

  12. By roughly 2050……our numbers will likely have increased to 9 billion(c. 2026 – 8 billion & c. 2043 – 9 billion).Nearly all growth will take place in developing countries, where the demand for food & water already outstrips supply.
