What percentage of health outcomes are determined by where you live?
Up to 80%. Health outcomes are shaped by social, economic, and environmental factors — where people live, work, and play — while clinical care accounts for as little as 10–20%. The entire healthcare software industry is built on the 20%. Variate is the operating layer for the 80%.
Where the number comes from.
The 80% framing traces to two primary sources. The World Health Organization's Commission on Social Determinants of Health (2008) established the framework that health outcomes are predominantly produced outside the clinical encounter. The University of Wisconsin Population Health Institute's County Health Rankings model operationalized it, allocating health outcome variance across physical environment, social and economic factors, clinical care, and health behaviors — with clinical care the smallest slice.
We state the uncertainty on purpose. A number that survives a board packet is a number with its sources attached — which is the same standard we hold our own engine to: every answer ships with a receipt.
