It isn't so much about counting things as finding ways of estimating the number of something,
One Wired article tried to figure out how many celebrities there were in the world. It looked to the category of Living People on Wikipedia. There are 604,174 pages on notable people. At the time the total global population was just over 7 billion so the fraction of living famous people was 0.000086. If the calculation was just for English-speaking population the number comes out to between 1 in 10,000 and 5 in 10,000. That's how many celebrities there are - a lot to track if you are in the celebrity-tracking business.
You might want to count other things besides our planet's population and celebrities. I found the world meters site and it is constantly counting things for us - current population, births, deaths, government spending, new books, newspapers circulated, emails sent today, blog post written, forest loss, undernourished people, overweight people, water used this year, energy used,, oil pumped, days to the end of oil, days to the end of coal, deaths caused by cancer, number cigarettes smoked today, This is the site I was looking at: https://www.worldometers.info/
We might wonder about who were history's great "counters." In today's terminology it would statisticians. It turns out that Florence Nightingale was one of them. Nightingale was a member of the Royal Statistical Society and one of the first people to collect statistics on health policy. Her work led to health policy reforms in 19th-century Britain and saved the lives of countless British soldiers. She presented the statistics of soldier deaths from preventable causes (such as unsanitary conditions) in a graphical pie chart diagram, making the information instantaneously understandable. The diagram is now called a polar-area diagram. She was one of the first statisticians to represent data in diagrams. |
