The infant mortality rate is the number of infant deaths in a single year for every 1,000 live births in the same year.
The infant mortality rate calculates the number of infant deaths in the first year of life divided by the number of live births multiplied by 1000.
The infant mortality rate is the key information about overall health of maternal and infant, and reflects the social, economic and environmental conditions in which children (and others in society) live. The infant mortality rate can be compared in different geographical regions or to capture the trends by year. Different causes of infant mortality could be investigated after.
For example, The infant mortality rate for Thailand in 2022 was 6.882 deaths per 1000 live births, a 3.07% decline from 2021.
Afghanistan, Somalia, the Central African Republic, Equatorial Guinea, and Sierra Leone are among the top five countries with the highest infant mortality rate in the world in 2021.
