Final answer:
To calculate the crude birth rate (CBR) for a place "A", divide the number of live births by the mid-year population and multiply by 1,000, resulting in a CBR of 15 births per 1,000 people per year.
Step-by-step explanation:
The student is asking how to find the crude birth rate (CBR) for a given population. To calculate the CBR, you take the number of live births in a year and divide it by the mid-year population, then multiply the result by 1,000. For place "A" with 2,400 live births and a mid-year population of 160,000, the calculation would be:
CBR = (Number of Live Births ÷ Mid-year Population) × 1,000
CBR = (2,400 ÷ 160,000) × 1,000
CBR = 0.015 × 1,000
CBR = 15 births per 1,000 people per year.
