«A mortality rate – often confused with a CFR – is a measure of the number of deaths (in general, or due to a specific cause) in a population, scaled to the size of that population, per unit of time.[2] Technically, CFRs, which take values between 0 and 1, are actually a measure of risk (i.e., a proportion of incidence). They are not ratios — none of which are limited to the range of 0 to 1 nor are they rates or incidence densities.»
