How to Use This Calculator

Enter the number of deaths observed in the study population.
Input the population at risk (central exposed-to-risk).
Set the study period in years.
Review the crude mortality rate per 1,000 lives.
Standardize against a reference population to compare across groups with different age distributions.

How the result changes with Population Size

Population Size	Crude Mortality Rate	Annual Death Probability	Survival Probability
40,001	20 per 1000	2%	98%
140,001	5.71 per 1000	0.57%	99.43%
260,000	3.08 per 1000	0.31%	99.69%
360,000	2.22 per 1000	0.22%	99.78%

Mortality Rate = (Deaths / Population) × 1000
