A country with mid-year population of 10 lac has Crude death rate of 20. Calculate the total no. of deaths per year?
**Core Concept**
The Crude Death Rate (CDR) is a demographic measure that calculates the number of deaths per 1,000 people in a population over a specific period, usually a year. It is an essential indicator of a population's health status and mortality patterns.
**Why the Correct Answer is Right**
To calculate the total number of deaths per year, we use the formula: CDR = (Total number of deaths in a year / Mid-year population) × 1,000. Given the CDR is 20, we can rearrange the formula to find the total number of deaths: Total number of deaths = (CDR × Mid-year population) / 1,000. Substituting the given values, Total number of deaths = (20 × 10 lac) / 1,000 = 2,000.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option does not provide a valid calculation for the total number of deaths.
* **Option B:** This option incorrectly uses the formula for Crude Birth Rate (CBR) instead of CDR.
* **Option C:** This option fails to account for the mid-year population in the calculation.
* **Option D:** This option does not provide a clear or correct calculation for the total number of deaths.
**Clinical Pearl / High-Yield Fact**
Remember that the Crude Death Rate is a useful tool for comparing mortality rates between different populations or over time, but it has its limitations, such as not accounting for age structure or other demographic factors.
**Correct Answer:** **A**. 2000.
