The Best Places to Live
It's impossible to say what's "best" for everyone, of course. But where's the fun in not trying? Welcome to Businessweek.com’s second America’s Best Cities ranking. With assistance from Bloomberg Rankings, Businessweek.com evaluated 100 of the country’s largest cities based on leisure attributes (the number of restaurants, bars, libraries, museums, professional sports teams, and park acres by population); educational attributes (public school performance, the number of colleges, and graduate degree holders), economic factors (2011 income and June and July 2012 unemployment), crime, and air quality. Major professional league and minor league teams, as well as U.S.-based teams belonging to international leagues in that city were included. The greatest weighting was placed on leisure amenities, followed by educational metrics and economic metrics, and then crime and air quality. The data come fromOnboard Informatics, except for park acreage, which comes from the Trust for Public Land. As the methodology has changed since the 2011 ranking, a city’s rise or fall compared with last year does not suggest that it has gotten “better” or “worse.”
