Regarding crude birth rate all are true except –
**Core Concept**
Crude birth rate (CBR) is a demographic measure that represents the number of live births per 1,000 people in a population per year. It is a widely used indicator of fertility and reproductive health in a given area.
**Why the Correct Answer is Right**
The CBR is calculated by dividing the total number of live births in a year by the mid-year population and then multiplying by 1,000. This measure is useful for comparing fertility rates across different populations and over time. A high CBR indicates a high fertility rate, which can be associated with various social, economic, and health outcomes.
**Why Each Wrong Option is Incorrect**
**Option A:** Crude birth rate is a measure of fertility, but it does not account for the age structure of the population, which can affect the interpretation of the results. A population with a large proportion of young people may have a high CBR due to the age structure rather than high fertility rates.
**Option B:** Crude birth rate is calculated by dividing the total number of live births by the mid-year population, but it does not account for the number of deaths in the population. A high CBR can be influenced by both high birth rates and low death rates.
**Option C:** Crude birth rate is a useful indicator of fertility, but it does not account for the quality of healthcare and mortality rates in the population. A high CBR can be influenced by various factors, including access to healthcare and prenatal care.
**Clinical Pearl / High-Yield Fact**
The crude birth rate is a basic demographic measure that can provide valuable insights into fertility and reproductive health in a population. However, it is essential to consider other demographic indicators, such as the general fertility rate and total fertility rate, to get a more comprehensive understanding of population dynamics.
**Correct Answer:** D
