Life expectancy Life expectancy is an average number of years that a person can expect to live in "full health" by taking into account years lived in less than full health due to disease and/or injury (WHOStat 2006). Crude Death/Mortality Rate (CDR) Crude Death Rate or Crude Mortality Rate is the total number of deaths to residents in a specified geographic area such as a country divided by the average total population for the same geographic area for a specified time period and multiplied by 100,000. The term crude means it does not account for age, sex or other variables in any aspects of death. CRUDE DEATH RATE=(Total deaths per year)/(Average Total population of that year) X 100 000 CAUSE-SPECIFIC DEATH RATE Cause-specific death …show more content…

CASE FATALITY RATE Case fatality rate is also called case fatality ratio. It is defined as the proportion of people who die from a specified disease among all individuals diagnosed with that specific disease over a certain period of time. Case fatality rate is typically used as a measure of disease severity and is often used for prognosis (predicting disease course or outcome), where comparatively high rates are indicative of relatively poor outcomes. Case fatality rate is calculated by dividing the number of deaths from a specified disease over a defined period of time by the number of individuals diagnosed with the disease during that time; the resulting ratio is then multiplied by 100 to yield a percentage as showed below: Case fatality rate =(the number of deaths from a specified disease for a specified period of time)/(the number of individuals diagnosed with the same disease during that
