How to Calculate Crude Birth Rate: Crude Birth Rate of Nepal

This post is dedicated to how to Calculate the Crude Birth Rate and crude birth rate of Nepal. The Crude Birth Rate (CBR) is a statistical value that can be utilized to measure the changes in a population in a particular place. The crude birth rate (CBR) is measured by the rate of births among a population of 1000. Say Crude birth rate (CBR) is the total number of live births per thousand midyear population of a particular place or a country in a specific year. The crude birth rate (CBR) helps to find out the direction of development of a country. It means The crude birth rate of Nepal helps to find out the direction of development of Nepal.

Midyear population refers to the population of July 1 of that year or the average population that can be obtained by adding the population of January 1 and the population of December 31 and dividing the sum by 2.

Crude birth rate (CBR) is expressed in per thousand because when it is calculated in hindered, it comes in a very small number.

The following formula is used to calculate the crude birth rate (CBR) to find out the crude birth rate of Nepal.

CBR = B/P *1000

Where,

CBR = Crude Birth Rate

B = total number of live births in a place or country in a fixed year

P = total mid-year population of the place in a year

Midyear population is calculated by adding the population of Jan 1 and December 31 of the given year and dividing the sum by 2.

P = (P1+P2)/2

Here,

P1 = Population of Jan 1

P2 = Population of Dec 31

P = Mid-year population

For an example of How to Calculate the Crude Birth Rate

Suppose that, in census 2011, the census day was June 22 (Asadh). Considering the day as mid-year, let us study how the following problem is solved.

The total population of Nepal in 2001 was 2,31,51,423. When the total number of live births in the year was 7,66,312, find out the crude birth rate (CBR).

Here,

Total number of live birth in Nepal in 2001 (B) = 766312

Total midyear population of the year (P) = 2315423

Crude Birth Rate (CBR) =?

Now,

CBR = B/P *1000

= 766312/23151423 * 1000

= 33.10

So, CBR = 33.10 birth per thousand

Therefore, there were 33.1 live births per 1000 population in Nepal in 2001. The crude birth rate of Nepal is 33.1 per thousand.
