Colour-coded map of the crude death rates of countries, globally, based on WHO data for 2000–2005, presented per thousand persons in the population, per year.<unk> , or death rate, is a measure of the number of deaths (in general, or due to a specific cause) in a particular population, scaled to the size of that population, per unit of time.<unk>  is typically expressed in units of deaths per 1,000 individuals per year; thus, a<unk>  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 "morbidity", which is either the prevalence or incidence of a disease, and also from the incidence rate (the number of newly appearing cases of the disease per unit of time). An important specific<unk>  measure is the crude death rate, which looks at<unk>  from all causes in a given time interval for a given population. , for instance, the CIA estimates that the crude death rate globally will be 7.7 deaths per 1,000 people in a population per year. In a generic form,<unk> s can be seen as calculated using , where d represents the deaths from whatever cause of interest is specified that occur within a given time period, p represents the size of the population in which the deaths occur (however this population is defined or limited), and is the conversion factor from the resulting fraction to another unit (e.g., multiplying by to get<unk>  per 1,000 individuals).
