World Population Clock: 7.6 Billion People World Population: Past, Present, and Future (move and expand the bar at the bottom of the chart to navigate through time) The chart above illustrates how world population has changed throughout history. At the dawn of agriculture, about 8000 B.C., the population of the world was approximately 5 million. A tremendous change occurred with the industrial revolution: whereas it had taken all of human history until around 1800 for world population to reach one billion, the second billion was achieved in only 130 years (1930), the third billion in 30 years (1960), the fourth billion in 15 years (1974), and the fifth billion in only 13 years (1987). During the 20th century alone, the population in the world has grown from 1.65 billion to 6 billion. Wonder how big was the world's population when you were born? Growth Rate Yearly Growth Rate (%) Population in the world is currently (2018-2019) growing at a rate of around 1.07% per year (down from 1.09% in 2018, 1.12% in 2017 and 1.14% in 2016).
