Apparently, in that article at least, "safety" only related to natural stuff, i.e. weather. Silly me, I think that there is more to safety than natural disasters. The homicide/rape/assault/burgulary/other crime rates mean something to me also. Why live in a location with no severe weather if you are afraid to go to the store after 3pm???
Crime is a concern. But crime rates can be both deceiving and quite variable.
Crime can be a quite local affair. You can look up the crime rate of a city and easily overlook that the crime is largely limited to a few neighborhoods and a relatively small sector of the population. Stay out of those few blocks and from around those people and your actual risk is far less than what the crime statistics would otherwise suggest.
Even in the wrong neighborhood and among the wrong people there are some subsets of people who defy the statistics. Awareness, attitude, how you look and what your role is in the area can shift the odds in or against you. Nobody is entirely safe but some people consistently beat the odds.
Also it has to be noted that some of the worse, bloodiest and most egregious crimes have happened in rural areas. Areas with low crime rates and where people thought they were safe. When things go south in an isolated area they often go bad in a very big way.
Also crime is shifting. Gangs, under pressure from police and looking for easy pickings and gullible youths looking for thrills and acceptance, are moving into the rural areas. Marijuana growers and meth labs have also moved into the countryside. Some rural counties, areas which had little or no serious crime, now have higher violent crime rates than nearby cities. Cities that are still assumed to be more dangerous.
I don't think people can draw conclusions without careful study. Even if your relatively safe from street crime now it doesn't mean a gang or meth lab won't move in and change things. Unfortunately poor rural counties seldom have the resources to effectively deal with a crime wave.
