Social determinants of health: The keys to health in a city. Photo by the Centers for Disease Control.
Often, a person’s level of health is attributed to genetics and behavior choices. Decisions such as eating fruits and vegetables and learning the family history of chronic health conditions are seen as the keys to achieving a healthy lifestyle.
While these factors are critical, health is dictated by more than behavior and biology. Health is also shaped by factors known as social determinants of health. As defined by the Centers for Disease Control, social determinants of health are the:
“conditions in the environments in which people are born, live, learn, work, play, worship, and age that affect a wide range of health, functioning, and quality-of-life outcomes and risks.”

Social determinants work in conjunction with individual health factors and behaviors to shape a person’s health in a city. Photo by the Oregon Public Health Institute.
As the photo above illustrates, social determinants of health come in many varieties such as the:
- Quality of local schools;
- The amount healthy food options available;
- Access to transportation;
- Affordability of housing;
- Poverty and inequality.

Even in a city like Chicago (with an average life expectancy of 77.8 years), life expectancy differs by as much as 16 years between neighborhoods located along CTA train stops. Photo by the Center on Society and Health at Virginia Commonwealth University.
With data showing that there is a link between having a high level of education and income with good health, and life expectancy differing across communities within the same city by as much as 20 years, it is important now more than ever that city leaders make social determinants of health a priority of their public health plans.
In the new series “The Healthy City”, The Heart of a City will explore how cities across the country are delving into the social determinant arena. By highlighting innovative initiatives and unique partnerships, the series will illustrate how a city is not only a place to live, but a place where health and wellness can be achieved by all. We invite you to join us as we explore The Healthy City.
