Finland has a similar policy. Since 1958 every building above 3000m2 was required to have a bomb/fallout shelter. Current spec extends to buildings with more than 1200m2 (used to be 600m2 until 2011, which was deemed too expensive) floor space. In 2008 there were 43 000 shelters for 3,6 million people (total population 5,3M). Shelter should be no more than 250 meters away.
