Mortality Rates

  The crude mortality rate is calculated by dividing the number of deaths by the population at risk during a certain time frame and then multiplying a factor (typically 100,000). . As a true rate, it estimates the risk of dying overall or from a certain disease in a given year. It is computed with the following equation: Frequently Used Measures of Mortality Measure Numerator Denominator Per: 10n Crude death rate Total number of deaths during a given time interval Mid-interval population 1,000 or 100,000 Cause-specific death rate Number of deaths assigned to a specific cause during a given time interval Mid-interval population 100,000 Proportionate mortality Number of deaths assigned to a specific cause during a given time interval Total number of deaths from all causes during the same time interval 100 or 1,000 Death-to-case ratio Number of deaths assigned to a specific cause during a given time interval Number of new cases of same disease reported during the same time interval 100 Infant mortality rate Number of deaths among children < 1 year of age during a given time interval Number of live births during the same time interval 1,000 Maternal mortality rate Number of deaths assigned to pregnancy-related causes during a given time interval Number of live births during the same time interval 1,000 Activity 1 Overall and Cause-Specific Crude Mortality Rates 1.
