How many piano tuners are there in the entire world?
This question takes some basic knowledge about the population of the united states and the world…not really about piano tuners.First think about how many pianos there are and how often they are used. Pianos are typically owned by middle to upper class households, and are also found schools, churches, hotels, etc.
The US population is approx 300 million. Assuming that each household has 3 people in it, that leaves 100 mil lion households. Of those, 50 million are in the middle to upper class and may have pianos. Of those 50 million households, you can think that no more than 10 percent have pianos. (That is probably high…it may be more like 2-3%). Anycase, that leaves us with approximately 5 million households with pianos.Now you need to think about how many piano tuners it takes to maintain those pianos. I would say a typical piano tuner could tune approx 20 pianos a week (2 hours each), and given a full year, that is approximately 1000 pianos.
Now, how often do pianos need to be tuned? Once a year maybe? If that is the case, then there would be 1 piano tuner for every 1000 pianos. That mean approx 5000 piano tuners in the US.
Now think about the rest of the world, it’s population, and it’s wealth. I would guess that the US has 1/3 of the world’s pianos. Therefore, I would guess the total number of piano tuners in the world is approximately 15000.
