1. What is Infant Mortality Rate?

The Infant Mortality Rate (IMR) is a key demographic indicator that measures the number of infant deaths (under one year of age) per 1,000 live births in a given year. It is widely used as an important indicator of the overall health and well-being of a population.

2. How Does the Calculator Work?

The calculator uses the IMR formula:

\[ IMR = \frac{\text{Infant Deaths}}{\text{Live Births}} \times 1000 \]

Where:

Infant Deaths — Number of deaths of infants under one year of age
Live Births — Total number of live births in the same period

Explanation: The formula calculates the rate of infant deaths per 1,000 live births, providing a standardized measure for comparison across different populations and time periods.

3. Importance of IMR Calculation

Details: IMR is a critical indicator of population health, reflecting the availability and quality of healthcare, nutrition, sanitation, and overall socioeconomic conditions. It helps policymakers identify areas needing improvement in maternal and child health services.

4. Using the Calculator

Tips: Enter the number of infant deaths and live births for the same time period. Both values must be valid (infant deaths ≥ 0, live births > 0).

5. Frequently Asked Questions (FAQ)

Q1: What is considered a "good" IMR?
A: Lower IMR values indicate better health outcomes. Developed countries typically have IMR below 5, while developing countries may have IMR above 20.

Q2: How does IMR differ from child mortality rate?
A: IMR specifically measures deaths in the first year of life, while child mortality rate includes deaths of children under 5 years of age.

Q3: What are the main causes of infant mortality?
A: Common causes include birth defects, preterm birth, maternal pregnancy complications, Sudden Infant Death Syndrome (SIDS), and injuries.

Q4: How has IMR changed over time?
A: IMR has significantly decreased globally due to improvements in healthcare, nutrition, sanitation, and education about infant care.

Q5: Why is IMR multiplied by 1000?
A: Multiplying by 1000 converts the ratio to a rate per 1000 live births, making it easier to interpret and compare across populations.
