This article describes a ratio measure. In the standard operationalization, the numerator of the measure is number of abortions (view other ratio measures with this numerator) and the denominator of the measure is number of live births (view other ratio measures with this denominator). The denominator used for reporting is 1000. The measurement period is a variable.
The numerator counts the number of occurrences of an event during the measurement period.
The denominator counts the number of occurrences of an event.
Definition
The abortion ratio for a population, typically measured in a given year (but with the measurement period variable in principle) is the number of abortions for every 1000 live births in the population. In other words:
The abortion ratio could be any nonnegative real value, and in principle may be more than 1000 (indicating more abortions than live births).
Note that the abortion ratio does not take into account the pregnancies that result in spotaneous fetal death, either in the numerator or in the denominator.
