Infant Mortality Rate:

Understanding Infant Mortality Rate

The Infant Mortality Rate (IMR) is a critical public health indicator that measures the number of deaths of infants under one year of age per 1,000 live births in a given year. It reflects the health and well-being of a population, encompassing factors such as maternal health, access to quality healthcare, sanitation, nutrition, and socioeconomic conditions.

A high IMR can signal underlying issues within a healthcare system or broader societal challenges that impact the survival of newborns and young infants. Conversely, a low IMR is generally indicative of a well-developed healthcare infrastructure and positive socioeconomic factors.

Formula:

Infant Mortality Rate (IMR) = (Number of Infant Deaths / Number of Live Births) * 1000

In this calculator, you input the total number of live births in a specific period (usually a year) and the total number of deaths that occurred among those infants before they reached their first birthday. The calculator then applies the standard formula to provide the rate per 1,000 live births.

Example:

If a country had 500,000 live births in a year and experienced 2,000 infant deaths during that same period, the Infant Mortality Rate would be calculated as follows:

IMR = (2,000 / 500,000) * 1000 = 4

This means that for every 1,000 live births, there were 4 infant deaths.
