Medians and even more so, averages, tend to point out the sometimes hidden costs of living in a particular location. Of course, "Nice" being a somewhat subjective term, also adds the need foe personal choices before making a move to a new location. The
only reason I would consider moving to Florida would be to live closer to my granddaughters. But that kind of info is seldom factored into these kinds of surveys. The fact is, most people live near where they work. Their choices are limited by commute times and income. Similar houses are available almost every where in the USoA. Shopping choices are only slightly different, even in quite rural areas.
I guess my point is that ones opinion of where one lives, is based more on personal choices and finding community involvements that allow one to share with others. Whether that will be interpreted as "nice" by others, is almost irrelevant.
I suppose that our relative closeness to a corruptly managed, crime ridden, decaying city just
might have an effect on that ranking, also.
