검증된 단계별 안내1
Understand that the infant mortality rate (IMR) is a demographic and health indicator used in statistics to measure the frequency of infant deaths.
Recognize that IMR specifically counts the number of deaths of infants under the age of 1 year.
Note that IMR is calculated relative to the number of live births, not total pregnancies or stillbirths.
Express the IMR as the number of infant deaths per 1,000 live births in a given year and area, which standardizes the measure for comparison.
Summarize that the IMR provides insight into the overall health and living conditions affecting infants in a population.
