1. death rate; mortality rate
Wikipedia definition
2. Mortality rateMortality rate 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. Mortality rate is typically expressed in units of deaths per 1000 individuals per year; thus, a mortality rate of 9.5 (out of 1000) in a population of 100,000 would mean 950 deaths per year in that entire population, or 0.95% out of the total.
