I suspect that is a result of different cultural expectations related to who should be able to afford to own their own home - even if the homes don't last very long.
From my understanding the switch to stone was mostly for fire resistance. City walls lead to very dense cities where fire could spread rapidly. Stone walls with clay tile roofs make it much harder for any fire to spread within a building and to other buildings.
Today we would have the fire fighting techniques and more fire resistant wood panels, but old habits die hard (and we are used to buildings standing for hundreeds of years)
If Switzerland had the US rate, ~75 more people would die every year.
If the US had the Swiss rate, ~2800 people would live to see another year.
Put in normalized terms,
- 0.00028% of the Swiss pop. dies from fire annually
- 0.00116% of the US pop. dies from fire annually
- 0.001% of the US pop. dies from drowning annually
- 0.001% of the US pop. dies from exposure to mechanical force annually
- 0.006% of the US pop. dies from gunshot annually
- 0.01% of the US pop. dies from falling annually
- 0.015% of the US pop. dies from road injuries annually
- 0.03% of the US pop. dies from respiratory illness annually
Here's [0] a visualization I made of causes of mortality a few years back. Play around with this a little bit; it's pretty interesting looking at actual mortality rates.
