Public health professionals are concluding that our metropolitan environment influences our physical and mental health. A blog posting of December 8, 2016, went so far as to state that, " . . . One number stands above all others as the best indicator of good health. It's not your blood pressure, cholesterol level, average daily calories, or even the age at which your grandparents die. It's your zip code." And the website of the Robert Wood Johnson Foundation has a feature where you can type in your zip code to see data on average life expectancy. Picking up on this idea, the folks at Project for Public Spaces have prepared a report on "The Case for Healthy Placemaking: Improving Health Outcomes through Placemaking."
