Window Falling Accidents

An accident was reported of a young, 27 year old, woman falling from a window in Dubai. Has anybody collected statistics on these accidents worldwide? I'm sure in each country the society for the prevention of accidents has figures. How do you prevent accidents? In some parts of the USA this cannot happen. To prevent accidents, windows of high rise hotels in San Francisco cannot be opened far enough for anybody to get out.
In Canada back in 1967 Habitat dwellings were designed like pyramid steps so nobody could fall further than one storey. Soft surfaces such as lawn or the sort used in children's playgrounds can be provided under windows.
