Population at Risk Calculator

Turn a crisis scenario into a clear estimate of how many people are at risk, plus a severity breakdown (mild / moderate / severe).

Planning tool only. “At risk” can mean food insecurity, hunger risk, or a program eligibility estimate—use the definition that fits your report.

Inputs People + %

Enter your scenario

Provide the population size and the percent you consider “at risk.” Optionally, split that at-risk group into severity levels. This can be based on assessments, survey findings, market shocks, displacement, or your own planning assumptions.

Total people in the affected area.
Example: 25% at risk.
Severity mix within the at-risk group (optional)
These should add up to 100%. If they don’t, we’ll automatically normalize them.
Used to estimate households at risk.
If provided, we estimate the total kcal shortfall for the at-risk group (daily + annual).
Heads up: your severity percentages didn’t add to 100%, so we normalized them automatically.
Tip: If you arrived here from the Calories Deficit calculator, the page can prefill values via the URL (population, name, deficit). You can copy/share the URL after calculating.
