Suppose, 3500 babies were born in Banepa Municipality in the year 2078 B.S. and 224 of them died before the age of one year, then calculate the infant mortality rate of Banepa Municipality of that year.

Answer

Given:

  • Live births in Banepa Municipality in 2078 B.S. = 3500
  • Infant deaths (before age one year) = 224

Formula:

IMR=Number of infant deaths in a yearNumber of live births in the same year×1000\text{IMR} = \frac{\text{Number of infant deaths in a year}}{\text{Number of live births in the same year}} \times 1000

Calculation:

IMR=2243500×1000=0.064×1000=64\text{IMR} = \frac{224}{3500} \times 1000 = 0.064 \times 1000 = 64

Result: The infant mortality rate of Banepa Municipality in 2078 B.S. was 64 per 1000 live births.
