Meaning of crude birth rate in geography

Answer 1

Step 1: Understanding the Question:
This question asks for the meaning of a standard demographic measure used to compare how fast populations are adding new members through birth.

Step 2: Define the term.
Crude birth rate (CBR) is the number of live births in a year for every 1,000 people in a population, measured at the mid point of that year. It is called 'crude' because it does not adjust for the age or sex make up of the population.

Step 3: State the formula.
\[ CBR = \frac{\text{Number of live births in a year}}{\text{Mid year population}} \times 1000 \]

Final Answer:
Crude birth rate is the number of live births per 1,000 people in a year, a simple measure of how fast a population is growing through births.\[ \boxed{CBR = \dfrac{\text{Births}}{\text{Population}} \times 1000} \]
