FWIW fire deaths have gone down by half since the 70s. Perhaps you could attribute this to fire alarms or better automatic sprinklers but overall this is a very good trend given population trends.
I'm also fairly certain that better fire retardant materials are used now and that's why wooden structures are allowed.

- emodendroket 5y agoI read a lot about these in local news because I used to live in a town in Massachusetts where one of those buildings burned down in construction. According to what I read, it's mostly the sprinklers that make it safe (or at least viewed that way) -- before those go in they're a big tinder box. This trend really took off with building code changes in 2009 though, so 1970 might not be the right starting point.

- handmodel 5y agoI guess my larger point is if risk of death by fire gets cut in half because of variables other than extra staircases - then the benefit of adding extra staircases gets cut in half while the cost remains the same (or even increases).
