Vital rates refer to how fast vital statistics change in a population (usually measured per 1000 individuals). There are 2 categories within vital rates: crude rates and refined rates.
Crude rates measure vital statistics in a general population (overall change in births and deaths per 1000).
Refined rates measure the change in vital statistics in a specific demographic (such as age, sex, race, etc.).
Famous quotes containing the words vital and/or rates:
“What a country calls its vital economic interests are not the things which enable its citizens to live, but the things which enable it to make war. Petrol is more likely than wheat to be a cause of international conflict.”
—Simone Weil (19091943)
“In the U.S. for instance, the value of a homemakers productive work has been imputed mostly when she was maimed or killed and insurance companies and/or the courts had to calculate the amount to pay her family in damages. Even at that, the rates were mostly pink collar and the big number was attributed to the husbands pain and suffering.”
—Gloria Steinem (20th century)
