--- title: "How many steps do you take in a lifetime? roughly 150 million " description: "roughly 150 million — about 110,000 km How the figure is estimated, how confident it is, and what makes the scale graspable." url: https://atoneplace.net/how-many/steps-in-a-lifetime/ site: "At One Place" --- # How many steps do you take in a lifetime? **How many steps do you take in a lifetime?: roughly 150 million — about 110,000 km** A lifetime of walking covers about 2.7 times the circumference of the Earth — or roughly a third of the way to the Moon. A large study using smartphone accelerometer data from 717,000 people put the global average at 4,961 steps a day, with enormous national variation: Hong Kong averaged 6,880 and Indonesia 3,513. At about 5,000 steps a day over 80 years that is roughly 146 million steps. At a 75 cm stride, that is about 110,000 km on foot. Someone hitting the popular 10,000-step target every day would double it. ## How the figure is arrived at 5,000 steps/day × 365.25 × 80 years = 146 million steps; × 0.75 m per step = 110,000 km. The step-count input is unusually good for a behavioural figure because it comes from passive phone sensors rather than self-report, though it under-counts anyone who leaves their phone behind. ## How confident it is - **Low estimate:** 100,000,000 - **High estimate:** 250,000,000 - **Spread:** 2.5× between the bounds > The 10,000-steps target has no clinical origin — it began as a 1960s Japanese pedometer marketing slogan, because the character for 10,000 resembles a walking figure. ## Other every day counts - [How many babies are born each day?](https://atoneplace.net/how-many/babies-born-a-day/) — about 360,000 — roughly four every second - [How many people die each day?](https://atoneplace.net/how-many/deaths-a-day/) — about 170,000 — roughly two every second - [How many Google searches are made every day?](https://atoneplace.net/how-many/searches-made-a-day/) — roughly 8.5 billion — about 100,000 a second - [How many emails are sent every day?](https://atoneplace.net/how-many/emails-sent-a-day/) — about 360 billion - [How many times does your heart beat in a lifetime?](https://atoneplace.net/how-many/heartbeats-in-a-lifetime/) — about 2.5 billion - [How many cups of coffee are drunk every day?](https://atoneplace.net/how-many/coffee-drunk-a-day/) — roughly 2.5 billion - [How many photos are taken every day?](https://atoneplace.net/how-many/photos-taken-a-day/) — roughly 5 billion a day — about 2 trillion a year - [How many hours of video are uploaded to YouTube every minute?](https://atoneplace.net/how-many/video-uploaded-a-day/) — 500 hours a minute — about 720,000 hours a day - [How many pizzas are sold every day?](https://atoneplace.net/how-many/pizzas-sold-a-day/) — somewhere between 3 and 8 million a day in the United States - [How many words do we speak a day?](https://atoneplace.net/how-many/words-spoken-a-day/) — about 16,000 - [How many breaths do you take in a lifetime?](https://atoneplace.net/how-many/breaths-in-a-lifetime/) — about 600 million - [How many messages are sent every day?](https://atoneplace.net/how-many/whatsapp-messages-a-day/) — about 100 billion on WhatsApp alone ## Common questions ### How many steps do you take in a lifetime? roughly 150 million — about 110,000 km ### How is that estimated? 5,000 steps/day × 365.25 × 80 years = 146 million steps; × 0.75 m per step = 110,000 km.
