The US Social Determinants of Health Atlas is a study conducted by researchers at the University of Chicago and the American Hospital Association, which used publicly available data to analyze 15 social factors that determine health outcomes in the US. The team created four indexes to group these factors into distinct categories, including Socioeconomic Advantage Index, Limited Mobility Index, Urban Core Opportunity Index, and Mixed immigrant cohesion and accessibility index. They also identified seven neighborhood typologies across the country, which were found to be associated with premature mortality rates. The study revealed a direct relationship between social determinants of health and premature mortality rates, highlighting the importance of addressing social inequity in public policy to save lives.
