Mortality Rates

US Mortality Statistics

-From death certificates collected from 50 states and DC -Deaths ranked by number of deaths from each cause of death -Group by age, sex, and race

Mortality Statistics come from information in death certifications

-U.S filed in a death registration area (a geographic area for which mortality data are published) -U.S-public health and the National Center for Health Statistics process these and produce statistics

Crude mortality rate equation

All deaths during a calendar year/ average total population at midyear of population at midyear x 100,000= number of deaths per 100,000 population in that year

Mortality

Death

Cause specific mortality rate equation

Deaths from the disease in a certain year/ average total population at midyear or population at midyear x 100,000

Proportionate Mortality Ratio (PMR) Equation

Deaths from the disease in a certain year/total deaths (not total population) x 100

Survival Rates Equation

Number of cases alive at end of time period/ Number of cases at beginning of time period x 100

Case Fatality Rate Equation

Number of deaths due to a disease in a specified time period/ Number of cases of the disease in the same time period x 100

Maternal Mortality equation

Number of deaths from puerperal causes in a year/Number of live births in a year x 100,000 live births

Infant Mortality equation

Number of infant deaths in a year/ Number of live births in a year x 1,000 live births

Infant Mortality

Rate at which infants die during the first year of life Important indicator of the health status of a population Reflects the health status of the mother and baby during pregnancy and birth

Crude mortality rate

The population who die every year

Case Fatality Rate

The probability of death among people diagnosed with a certain disease

Maternal Mortality

The rate at which women die in childbirth or because of pregnancy complications in a particular population

Survival Rates

To measure how many people with a certain condition are still alive after a certain time period

Specific

To measure the rate of death in a particular population subgroup or from particular disease

Crude

To measure the rate of death of the total population

Adjusted

To take account of age differences between two population

Cause specific mortality rate

Used to show the number of deaths due to a specific cause

Proportionate Mortality Ratio (PMR)

Used to show the proportion of all deaths due to a specific cause
