Mortality

This type of demographic history examines changes in death rates over time and the various factors that contribute to mortality rates, such as disease, nutrition, medical advances, and social conditions.

What is the definition of mortality rate?

Quote: "Mortality rate, 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."

How is mortality rate typically expressed?

Quote: "Mortality rate is typically expressed in units of deaths per 1,000 individuals per year."

Can you explain the crude death rate?

Quote: "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."

What does the CIA estimate the global crude death rate to be in 2020?

Quote: "As of 2020, 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."

How can mortality rates be calculated?

Quote: "(d/p) · 10^n, 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, and 10^n is the conversion factor from the resulting fraction to another unit."

What is the relationship between mortality rate and morbidity?

Quote: "It is distinct from 'morbidity', which is either the prevalence or incidence of a disease."

What is the difference between mortality rate and incidence rate?

Quote: "It is distinct from the incidence rate (the number of newly appearing cases of the disease per unit of time)."

How is morbidity different from mortality rate?

Quote: "It is distinct from 'morbidity', which is either the prevalence or incidence of a disease."

How is mortality rate measured in relation to population size?

Quote: "Mortality rate is a measure of the number of deaths in a particular population, scaled to the size of that population."

What does a mortality rate of 9.5 (out of 1,000) imply?

Quote: "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."

How is mortality rate different from morbidity?

Quote: "It is distinct from 'morbidity', which is either the prevalence or incidence of a disease."

Is mortality rate specific to a particular cause of death?

Quote: "Mortality rate is a measure of the number of deaths (in general, or due to a specific cause) in a particular population."

Can you define the unit used to express mortality rate?

Quote: "Mortality rate is typically expressed in units of deaths per 1,000 individuals per year."

What is the purpose of the conversion factor in mortality rate calculation?

Quote: "10^n is the conversion factor from the resulting fraction to another unit (e.g., multiplying by 10^3 to get mortality rate per 1,000 individuals)."

How is the morbidity of a disease different from its mortality rate?

Quote: "It is distinct from 'morbidity', which is either the prevalence or incidence of a disease."

What does a crude death rate measure?

Quote: "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."

Is the crude death rate specific to any particular population?

Quote: "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."

When did the CIA estimate the global crude death rate?

Quote: "As of 2020, 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."

How can mortality rates be seen as calculated?

Quote: "Mortality rates can be seen as calculated using (d/p) · 10^n, where d represents the deaths from whatever cause of interest is specified, p represents the size of the population in which the deaths occur, and 10^n is the conversion factor from the resulting fraction to another unit."

How is mortality rate related to the size of a population?

Quote: "Mortality rate, or death rate, is a measure of the number of deaths in a particular population, scaled to the size of that population."
