Question

In a town of 1,20,000 people, there were 1,500 births and 1,200 deaths in a year. Calculate the CBR and CDR.

Hint:

CBR/CDR formula: \( \frac{\text{Events}}{\text{Population}} \times 1000 \)

Answer 1

Concept: Crude Birth Rate (CBR) and Crude Death Rate (CDR) are calculated as the number of births or deaths per 1000 population per year. \[ \text{CBR} = \frac{\text{Number of live births}}{\text{Mid-year population}} \times 1000 \] \[ \text{CDR} = \frac{\text{Number of deaths}}{\text{Mid-year population}} \times 1000 \]
Given:

Total population = 1,20,000
Number of births = 1,500
Number of deaths = 1,200


Step 1: Calculate CBR \[ \text{CBR} = \frac{1500}{120000} \times 1000 \] \[ \text{CBR} = 12.5 \]

Step 2: Calculate CDR \[ \text{CDR} = \frac{1200}{120000} \times 1000 \] \[ \text{CDR} = 10 \]
Final Answers:

Crude Birth Rate (CBR) = 12.5 per 1000 population
Crude Death Rate (CDR) = 10 per 1000 population
