Question

In 2019, there were 3,250 births in a city with population of 2,23,000. Therefore:

`"CBR" = (3,250)/(2,23,000) xx 1,000 = 14.57`

So, at that time, there were 14.57 live births for every 1,000 people in the city.

• Can you calculate the death rate in the above example, if the total number of deaths in the city was 2,986 in the same year?
• On the basis of the Birth Rate given earlier and Death Rate calculated by you, what change in population do you observe?

Answer 1

Crude Death Rate (CDR):

`"CDR" = "Number of deaths"/"Total population" xx 1000`

= `(2,986)/(2,23,000) xx 1000 = 13.39`

So, the death rate is 13.39 deaths per 1,000 people.

Change in Population:

Birth Rate = 14.57 per 1,000
Death Rate = 13.39 per 1,000

Since the birth rate is higher than the death rate, the population will increase slightly.

Increase in population:

3,250 − 2,986 = 264

So, there is a natural increase of 264 people in that year.
