Question

What is meant by crude death rate?

Answer 1

Hint: Crude Death Rate (CDR) is a statistical term. It is used for measuring the decline in the population. The word crude is used because age or sex is not taken into account for making differences among the population. The opposite of the Crude death rate is the measuring of growth of population which is called the Crude Birth rate (CBR). Both of these are measured per 1000 population.

Complete answer:
The number of deaths occurring in a population for a given geographical area during a given year per 1000 mid-year of the total population is called Crude Death Rate. If the CDR is less than 10 per 1000 then it will be considered as low whereas if CDR is more than 20 per 1000 then it will be considered as high.

The formula of Crude death rate is:
CDR = $\dfrac{{Total{\text{ }}number{\text{ }}of{\text{ }}deaths{\text{ }}in{\text{ }}a{\text{ }}calendar{\text{ }}year}}{{Estimated{\text{ }}mid - year{\text{ }}population{\text{ }}that{\text{ }}year}} \times 1000$

The particular group of population death is not shown by the crude death rate. For example - an unhealthy town such as Bournemouth has a high crude death rate but when you examine closely then you will find that most people are retiring from jobs so the high proportion of people are of old age.

The effects due to which crude death increase are:
- Due to the increased risk of diseases in the population.
- The food supply is disturbed due to which people are starving.
- Due to bad medical healthcare facilities.
- Due to improper hygiene and contaminated supply of water.
- Due to an increased population of old age rather than young or middle age.

Note: So basically crude death rate is the measuring of death in a population. People will birth and die which is a natural process but a sudden increase in death in any country forces the crude death rate to be measured. A large group of the population can die due to a variety of reasons. The healthcare facilities should be maintained properly so that if people are infected then they can cure easily and decrease the crude death rate.
