The crude death rate is defined as the number of deaths occurring during the year, per _____ population estimated at midyear.

Correct option is B

Sol. The crude death rate (CDR) is defined as the total number of deaths per 1,000 population per year. It is a basic measure of mortality within a population and is calculated using the formula:
CDR=(Total deaths in a yearTotal mid-year population)×1000CDR = \left( \frac{\text{Total deaths in a year}}{\text{Total mid-year population}} \right) \times 1000CDR=(Total mid-year populationTotal deaths in a year​)×1000
A high CDR may indicate poor healthcare, high disease burden, or an aging population.
Explanation of Each Option:
· 10,000: Incorrect; mortality rates are measured per 1,000 people, not 10,000.
· 1,000: Correct answer; crude death rate is measured per 1,000 population.
· 100: Incorrect; used for infant mortality rate but not for crude death rate.
· 100,000: Incorrect; used for maternal mortality ratio, not crude death rate.
