Each day, around eight billion people wake up and navigate life by performing a multitude of activities. Some spend hours at work, others look after their children, cook, entertain themselves, or take time for themselves. But if we combined all these experiences into a single average day, what would it look like? A team of researchers from McGill University set out to answer this question by collecting data from 145 countries. Their analysis, published in 2023 in the Proceedings of the National Academy of Sciences, offers a fascinating and previously unseen view of how humanity spends its time.
Time, a universal resource but unevenly distributed
The study shows that an average human spends about 9.1 hours per day sleeping or resting. This figure may seem high for an active adult, but it includes the sleep needs of babies, children, and the elderly.
Once awake, the typical person dedicates 4.6 hours to leisure and social interactions. This time encompasses activities such as watching television, playing, reading, engaging in artistic pursuits, meeting friends, or simply doing nothing.
Meals and their preparation take on average 2.5 hours per day, while personal hygiene (washing, dressing, caring for oneself) accounts for about 1.1 hours. Household upkeep, including cleaning and maintaining living spaces, requires an average of 0.8 hours per day.
Work, often seen as a dominant activity, actually accounts for only 2.6 hours per day on average. This duration is far shorter than a standard workday, a discrepancy explained by the fact that many people do not work (children, retirees, homemakers, unemployed), which lowers the global average. Likewise, education, which mainly concerns younger generations, represents only 1.1 hours per day across the world population.
Finally, a striking finding concerns essential productive activities such as construction, manufacturing of goods, and resource extraction. These tasks occupy only 0.8 hours per day on average, meaning that the construction of human infrastructures – roads, houses, everyday objects – engages just 3% of the world’s collective time.
Disparities between rich and poor countries
Even though these figures reflect a global average, they mask significant regional differences around the world.
In high-income countries, individuals spend about 1.5 hours more each day on leisure, meals, and physical activities than those living in poorer nations. Conversely, in the least advantaged regions, a much larger share of time is devoted to fundamental tasks such as farming and harvesting food. While in wealthy countries a person spends on average only 5 minutes per day producing their food, this activity takes more than an hour daily in the poorest countries.
Nevertheless, some habits transcend borders. Across the globe, we devote a relatively similar amount of time to eating, traveling, hygiene, and personal care.
Why is this study important?
This work marks the first major publication of the Human Chronome Project, an initiative aimed at building a global database on the organization of human time. By understanding how we collectively distribute our time, researchers hope we can better manage this precious resource and consider ways to optimize our way of living.
Behind these statistics, a fundamental question arises: are we using our time in the best possible way? The distribution of hours within the “global human day” offers a fascinating snapshot of our civilization and its priorities. As the world faces major challenges—climate change, automation of work, artificial intelligence—this study could help us make more informed decisions about how we want to use our time, both as individuals and as a species.
After all, time is the only truly universal resource. It is up to each person to decide how to spend it.
