Vital Rates

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:

    The old parties are husks, with no real soul within either, divided on artificial lines, boss-ridden and privilege-controlled, each a jumble of incongruous elements, and neither daring to speak out wisely and fearlessly on what should be said on the vital issues of the day.
    Theodore Roosevelt (1858–1919)

    [The] elderly and timid single gentleman in Paris ... never drove down the Champs Elysees without expecting an accident, and commonly witnessing one; or found himself in the neighborhood of an official without calculating the chances of a bomb. So long as the rates of progress held good, these bombs would double in force and number every ten years.
    Henry Brooks Adams (1838–1918)
