Mortality rate

Mortality rate, or death rate,: 189, 69  is a measure of the number of <a href="/facts/Death/VJmq29qm">deaths</a> (in general, or due to a specific cause) in a particular <a href="/facts/Statistical_population/KAILs8E3">population</a>, scaled to the size of that population, per unit of time. Mortality rate is typically expressed in units of deaths per 1,000 individuals per year; thus, a mortality rate of 9.5 (out of 1,000) in a population of 1,000 would mean 9.5 deaths per year in that entire population, or 0.95% out of the total. It is distinct from "<a href="/facts/Morbidity/55eeQlGL">morbidity</a>", which is either the <a href="/facts/Prevalence/6UTuTGTH">prevalence</a> or <a href="/facts/Incidence_(epidemiology)/2BB3FlBK">incidence</a> of a <a href="/facts/Disease/55eeQlGL">disease</a>, and also from the <a href="/facts/Incidence_rate/2BB3FlBK">incidence rate</a> (the number of newly appearing cases of the disease per unit of time).: 189 [verification needed]
An important specific mortality rate measure is the crude death rate, which looks at mortality from all causes in a given time interval for a given population. As of 2020, for instance, the <a href="/facts/Central_Intelligence_Agency/U7urmQYL">CIA</a> estimates that the crude death rate globally will be 7.7 deaths per 1,000 people in a population per year. As of 2024, the global crude death rate stood at 7.76, marking a 2.35% rise compared to 2023. In a generic form,: 189  mortality rates can be seen as calculated using
