rate

 [rāt]
the speed or frequency with which an event or circumstance occurs per unit of time, population, or other standard of comparison.
adjusted rate a fictitious summary rate statistically adjusted to remove the effect of a variable, such as age or sex, to permit unbiased comparison between groups having different compositions with respect to these variables. See also crude rate and specific rate.
attack rate in the analysis of acute outbreaks of disease, the proportion of persons who are exposed to the disease during the outbreak who do become ill.
basal metabolic rate an expression of the rate at which oxygen is utilized in a fasting subject at complete rest as a percentage of a value established as normal for such a subject. Abbreviated BMR.
birth rate the number of live births in a geographic area in a defined period, usually one year, relative to some specified population. For the crude birth rate, it is the average total population or the midyear population in the area during the period. Specific birth rates for subsets of the population may also be calculated, for example, an age-specific birth rate is limited to the population of females of a defined age range.
case fatality rate the number of deaths due to a specific disease as compared to the total number of cases of the disease.
crude rate one giving the total number of events occurring in an entire population over a period of time, without reference to any of the individuals or subgroups within the population. See also adjusted rate and specific rate.
death rate the number of deaths in a certain period of time divided by the total of a given population. The crude death rate is the ratio of the number of deaths in a geographic area in one year divided by the average population in the area during the year. The age-specific death rate is the ratio of the number of deaths occurring in a specified age group to the average population of that group. The cause-specific death rate is the ratio of the number of deaths due to a specified cause to the average total population. Called also mortality rate.

DMF rate an expression of the condition of the permanent teeth based on the number of teeth decayed, missing (or indicated for removal), and filled or bearing restorations. It is calculated by adding the number of carious permanent teeth requiring filling (D), carious ones requiring extraction (Mr), ones previously extracted because of caries (Mp), and permanent teeth (F).

maternal mortality rate a rate in which the numerator is the number of maternal deaths ascribed to puerperal causes in one year; the number of live births in that year is often used as the denominator, although to make a true rate the denominator should be the number of pregnancies (live births plus fetal deaths). Called also puerperal mortality rate.

postneonatal mortality rate the ratio of the number of deaths in a given year of children between the 28th day of life and the first birthday relative to the difference between the number of the live births and neonatal deaths in that year; the denominator is sometimes simplified, less correctly, to the number of live births. The ratio is sometimes approximated as the difference between the infant mortality rate and the neonatal mortality rate.
