The chart above illustrates how world population has changed throughout history. View the full tabulated data. At the dawn of agriculture, about 8000 B.C., the population of the world was approximately 5 million. Over the 8,000-year period up to 1 A.D. it grew to 200 million (some estimate 300 million or even 600, suggesting how imprecise populatio...
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).
World population will therefore continue to grow in the 21st century, but at a much slower rate compared to the recent past. World population has doubled (100% increase) in 40 years from 1959 (3 billion) to 1999 (6 billion). It is now estimated that it will take another nearly 40 years to increase by another 50% to become 9 billion by 2037.
According to a recent study (based on the 2010 world population of 6.9 billion) by The Pew Forum, there are:

Worldometer, formerly Worldometers, is a reference website that provides counters and real-time statistics for diverse topics. It is owned and operated by a data company Dadax [failed verification] which generates revenue through online advertising.
The virus has infected and killed millions of people around the world. See detailed maps and charts for each country.
Differences in the population size between different countries are often large – it is insightful to compare the number of confirmed cases per million people. Keep in mind that in countries that do very little testing the actual number of cases can be much higher than the number of confirmed cases shown here.
