The influence of income, education, and other social factors is the clearest pattern in the latest annual rankings of health by county, with the upscale suburban counties of Bucks, Chester, and Montgomery all making the state's top 10, and Philadelphia last at 67.
Middle-income Delaware County places slightly better than middle for Pennsylvania. Ditto Burlington, Camden, and Gloucester Counties compared with the rest of New Jersey, according to the eighth annual County Health Rankings released Wednesday.
Counties are ranked in two ways: Health outcomes are based on length and quality of life (Chester County was No. 1 in the state). Health factors, which contribute to outcomes, are based on a range of measures, from smoking rates to poverty and availability of parks and recreation (Montgomery County was No. 1).
