There are 7,9 billion people in the world based on the latest United Nations data from 2022.
China and India vastly exceed others in terms of number of population in 2022. The population of China and India combined make up 35% of the global population. This means that for every ten people in the world right now, three of them are either Chinese or Indian.
Figure 1: Proportion of World Population in Continents in 2022
China is the most populous country with 1.425 billion people, while India is the second most populous with 1.417 billion people. United States is in the third place with 338 million people. Indonesia is in the fourth with 275 million people.

Asian continent makes up the majority of world’s population with 59%. So for every ten people, approximately five of them are Asian. Africa is the second most populous continent with 18% of the global population. Europe, North America and South America are next in the ranks with 9%, 8% and 5%, consecutively.
Figure 2
The least populous continent is Oceania with a population of 45 million people.
The average population of countries is 34 million people. Each of the top two most populous countries, i.e. China and India, has the population size at least 41 times that average population.
The frequency distribution of populations is very skewed towards the lower end of the histogram. Ninety-six percent of countries has population of less than 140 million. The average population of countries is 34 million people, which is about the size of Malaysia, Peru, or Uzbekistan. This average value, however, may not reflect the center point of the data because it is affected by the outliers on the larger part of the population spectrum. The median population of countries is 22 million people, which is about the size of Syria, Mali, or Sri Lanka.
Countries with the lowest number of population has the population of 0.01 million which is ten thousand people or less. Such countries are Nauru, Saint Barthélemy, Saint Helena, Saint Pierre and Miquelon, Tuvalu, and Wallis and Futuna Islands. All of the aforementioned countries are small islands in Oceania, North America, or Africa.
