Yes, and how many people have died during the construction and infrastructure boom in China/India/Africa. They're faster because they aren't as safety focused. For example: https://www.washingtonpost.com/archive/politics/2000/09/07/c...

How much is unreported?

This isn't to say this doesn't happen in western countries but it is less common. A large number of deaths was also associated with the Qatar world cup for example.

Look at the public reports of engineering and manufacturing companies. How many of them have a "target zero" approach to safety and report the TIFR as a key KPI? I've known executives in engineering organisations to be fired for persistent safety breaches making them substantially more risk averse.

This all costs more money and takes more time and I would posit that if China/India/Africa become wealthier and more individualistic then their construction rates would also slow.
