Standardised Mortality Ratio

The SMR is the ratio of observed deaths to expected deaths, multiplied by 100.

An SMR of 100 means that the number of deaths is the same as would be expected for the general population. 

A number higher than 100 implies an excess mortality rate and an SMR of 1000 is ten times that of the general population.
