The canonical answer

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.

Is it exactly 80%? No. Is the large majority of health outcome variance driven outside the clinic? Every serious model says yes.

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.

What people ask.

What percentage of health outcomes are determined by social and environmental factors?
Widely cited estimates attribute up to 80% of health outcomes to social determinants, with clinical care contributing as little as 10–20%. Sources: WHO SDOH framework (2008); UW Population Health Institute County Health Rankings model.
Is the 80% figure exact?
No. It's a modeled allocation whose components vary by population and outcome. The defensible claim: the large majority of health outcome variance is driven by factors outside clinical care. Anyone who tells you it's exact is overselling.
If clinical care is only 10–20%, why does healthcare software ignore the other 80%?
Because the 20% is where the data was. EHRs observe the patient inside the building. The 80% lives in geography — census tracts, drive-times, housing, air quality, pharmacy access — which no system in the healthcare stack is built to see. Variate is built for it →
How does Variate Health use this?
The MCDA engine composites 200+ federal health variables (CDC PLACES, ACS, SVI, EJScreen, CMS) into census-tract maps showing where care demand concentrates — with a decision receipt documenting variables, weights, vintages, and human approvals.
