Discounting all of the people in the astronomical twilight zone and half of the population experiencing nautical twilight, we get 7204.9 million people, or about 93% of the world’s population. So, the claim is technically true if you count all twilight areas, no matter how dimly lit.īut the percentage of the population actually perceiving sunlight is a bit lower. Especially in urban areas, whose residents make up a majority of the total population numbers, light pollution can blend out the faint glow of the Sun, which is 6-12 degrees below the horizon at that point. Moreover, many people in the slightly brighter nautical twilight zone will fail to notice any daylight. So, 256.8 million people, about 3% of the world’s population, are so far behind the curve that no sunlight is visible. ©/photographer3431 Hundreds of Millions Will Think It’s Night Over 6.4 billion of them are in the daytime, while more than 1.2 billion people experience twilight.Īstronomical twilight or nighttime? When the Sun is 12-18 degrees below the horizon, the naked eye usually fails to discern the trace amounts of indirect sunlight in the sky. That leaves about 7.7 billion people-roughly 99% of us-on the side of the planet illuminated by the Sun. When we run the detailed numbers through our computer, we also find some support for the claim.Ĭombining timeanddate’s Sun data with 2022 population data from the Center for International Earth Science Information Network at Columbia University, we found that it’s nighttime for just under 80 million people on July 8 at 11:15 UTC. 7.7 Billion People Get Some Degree of Sunlight Among them are North America, South America, Europe, Africa, and most of Asia.Īustralia, New Zealand, parts of Southeast Asia, and Antarctica are the only larger landmasses on the night side of Earth. Nearly all of the world’s most populated areas receive some sunlight at the time in question.
