8,000 an hour

Do you know how many books are sold before you have bestseller? Or how many patients go through emergency rooms? Or the significance of 8,000 an hour? No, then read on.

All authors would love for their latest book to become a best seller. But it’s not easy. Sales in the order of 3,000 per week are needed to get onto the New York Times best sellers list, so it helps if you are famous or get to chat with Oprah.

Here are some other numbers:

  • Hospital emergency departments vary in size but on average each ER treats 600 patients every week.
  • A medium–sized high school might have 1,500 students enrolled.
  • A suburban train with eight carriages can ferry 1,600 commuters at time from their homes to offices in the city.
  • A person who goes about their business but does not take much exercise will take 6,000 steps in a day, whilst active individuals might manage 10,000.
  • At rest a human adult will breathe steadily, roughly 12 times in a minute and 720 times in an hour.

And here is another one. Every hour of every day there are 8,000 more people on earth.

That is two and a half times the number of book buyers, the weekly throughput of 13 ERs, enough for five high schools, and the passengers from five commuter trains, every single hour of every day. If you prefer bigger numbers, 8,000 an hour grows to 192,000 per day, 1.3 million per week, and 70 million per year.

Every year there are more people added to the global population (births minus deaths) than there are Frenchmen. In two and a half days we add more people than there are elephants in Africa.

Amazing isn’t it. Staggering even.

Makes you think.
