Population burden as fraction or percent

Where this fits
Population attributable risk keeps the result as an absolute risk value. This page turns that same burden into a fraction and percent so you can explain the share of total population risk attributable to the exposure.
FAQ
What does this page calculate?
It estimates population attributable fraction and population attributable percent from exposure prevalence with group risk, or from direct attributable risk with total population risk.
How is this different from the population attributable risk page?
The population attributable risk page keeps the result as an absolute risk value. This page converts the same idea into fraction and percent form so you can explain the burden as a share of total population risk.
Why does direct mode ask for total population risk?
A fraction needs both a numerator and a denominator. Direct mode already gives attributable risk, so total population risk is needed to express the burden as a fraction or percent.
