Definition of each vital statistic:
Case-fatality rate: The proportion of individuals who have a particular condition (such as a disease) and die from it.
Mortality rate: The number of deaths in a population over a specific time period, typically expressed as the number of deaths per 1,000 people.
Age-specific mortality rate: The number of deaths in a specific age group over a specific time period, typically expressed as the number of deaths per 1,000 people in that age group.
Maternal mortality rate: The number of deaths of women from pregnancy-related causes per 100,000 live births.
Infant mortality rate: The number of deaths of children under one year of age per 1,000 live births.
Neonatal mortality rate: The number of deaths of children under 28 days of age per 1,000 live births.
How to calculate each vital statistic:
Case-fatality rate: The case-fatality rate can be calculated as the number of deaths due to a particular condition divided by the number of individuals who have that condition.
Mortality rate: The mortality rate can be calculated as the number of deaths in a population over a specific time period divided by the size of the population, typically expressed per 1,000 people.
Age-specific mortality rate: The age-specific mortality rate can be calculated as the number of deaths in a specific age group over a specific time period divided by the size of the population in that age group, typically expressed per 1,000 people in that age group.
Maternal mortality rate: The maternal mortality rate can be calculated as the number of deaths of women from pregnancy-related causes over a specific time period divided by the number of live births during that time period, expressed per 100,000 live births.
Infant mortality rate: The infant mortality rate can be calculated as the number of deaths of children under one year of age over a specific time period divided by the number of live births during that time period, expressed per 1,000 live births.
Neonatal mortality rate: The neonatal mortality rate can be calculated as the number of deaths of children under 28 days of age over a specific time period divided by the number of live births during that time period, expressed per 1,000 live births.
What are the main usefulness of each vital statistic:
Case-fatality rate: The case-fatality rate is useful for understanding the severity of a particular condition and the effectiveness of treatments or interventions for that condition.
Mortality rate: The mortality rate is useful for understanding the overall health of a population and for identifying trends in mortality over time.
Age-specific mortality rate: Age-specific mortality rates are useful for understanding the mortality patterns in different age groups and for identifying potential health disparities between age groups. They can also be used to inform public health policies and programs.
Maternal mortality rate: The maternal mortality rate is a key indicator of the health of women and their access to quality maternal health care. It is useful for identifying trends in maternal mortality over time and for evaluating the effectiveness of maternal health policies and programs.
Infant mortality rate: The infant mortality rate is a key indicator of the overall health and well-being of a population. It is useful for identifying trends in infant mortality over time and for evaluating the effectiveness of policies and programs aimed at improving child health.
Neonatal mortality rate: The neonatal mortality rate is a specific measure of infant mortality that focuses on deaths that occur within the first 28 days of life. It is useful for understanding the causes of infant mortality and for identifying opportunities for intervention to improve the health of newborns.
