Nursing QUESTION #9175
Question 1
A community health nurse calculates the Crude Birth Rate (CBR) of a district. The correct formula is:
\\text{CBR} = ?
  • \\frac{\\text{Number of live births}}{\\text{Mid-year population}} \\times 1000✔️
  • \\frac{\\text{Number of live births}}{\\text{Number of women aged 15-49}} \\times 1000
  • \\frac{\\text{Total deaths}}{\\text{Mid-year population}} \\times 1000
  • \\frac{\\text{Number of live births}}{\\text{Total births including stillbirths}} \\times 1000
Correct Answer Explanation

The Crude Birth Rate (CBR) is calculated as:

\\text{CBR} = \\frac{\\text{Number of live births in a year}}{\\text{Mid-year total population}} \\times 1000

It is expressed per 1,000 population. Pakistan's CBR is approximately 26–28 per 1,000 population.

Comparison with other fertility measures:

  • General Fertility Rate (GFR) uses women aged 15–49 as denominator
  • Total Fertility Rate (TFR) is the average number of children a woman would have in her lifetime
  • Option 3 is the formula for Crude Death Rate (CDR)
