A growing body of evidence is suggesting that the zip code where a person lives might be the single most accurate predictor for gauging lifespan. How you were raised, your 'level of education, peer influence, and health literacy are known as social determinants of health. Understanding these determinants and addressing them at the street level by community paramedics can have an impact on not only the longevity of the individual but the overall health of the neighborhood where the patient lives. It is not coincidence that high-crime areas have a proportionate EMS call volume. This class makes the point that if social determinants of health are addressed, the overall quality of life in a neighborhood can improve, further reinforcing the sentiment that healthy people make healthy neighborhoods and healthy neighborhoods make for a healthy community.'
