The Safest Cities in America 

以下の6つのメトリックでそれぞれの指標を出した後、

  • Violent crime rate. The number of violent crimes per 100,000 residents.
  • Vehicular mortality rate. The number of automobile accident deaths per 100,000 residents.
  • Drug poisoning mortality rate. The number of drug poisoning deaths per 100,000 residents. Drug overdoses are the most common cause of drug poisonings.
  • Population engaging in excessive drinking. The percentage of the population that consumed more than 4 (women) or 5 (men) drinks of alcohol over a 30-day period.
  • Air Quality Index. A measure of particulate matter, ozone and other forms of air pollution calculated by the EPA. Air pollution is a factor for many of the country’s most deadly medical conditions.
  • Commuters driving to work alone. The percentage of the workforce that gets to work by driving alone.

凶悪犯罪発生率は2倍の重み、ドラッグ致死率・重度飲酒率は重み0.5を加味してランキングしたらしいけど、我らがサンノゼは6位。これって計算間違ってないか?凶悪犯罪率が他の都市と比較してかなり高いんだけどなぁ。
