Birth rate equation :

[tex]\displaystyle CBR=\frac{number~of~births}{total~population~in~the~middle~of~the~ year}\times 1000[/tex]

Further explanation

Population growth from an area can be based on death and birth as well as the migration of its population

Can be formulated simply

Pt = Po + (B - D)

Pt = population at the end of the year

Po = population at the beginning of the year

B = Birth

D = Death

If you take into account the movement of the population:

Pt = Po + (Births + Immigration) - (Deaths + Emigration)

Birth Rate shows the number of births per 1000 population in that year

We can use the Crude Birth Rate (CBR) calculation

The formula used

[tex]\displaystyle CBR=\frac{number~of~births}{total~population~in~the~middle~of~the~ year}\times 1000[/tex]

A population has 1000 individuals. Over a period of 1 year, 500 new individuals are born.

number of births = 500

total population in the middle of the year (assumed) = 1000 + 250 = 1250

[tex]\displaystyle CBR=\frac{500}{1250}\times 1000\\\\CBR=\boxed{\bold{333.33}}[/tex]

To calculate the birth rate of this population we use this equation: 500 ÷ 1000 =  0.5

Explanation:

Birth rate is defined as the number of individuals born every year per 1000 people in a population. Birth rate is the number of individuals born into a population in a given amount of time. The average global birth rate is 18.5 births per 1,000 total population in 2016. With a fertility rate 7 children per woman, Niger is the highest fertility rate country in the world.

A population is the number of living people that live together in the same place/ city. There are three types of population pyramids such as expansive, constrictive, and stationary.

  1. Expansive population pyramids is populations that have a larger percentage of people in younger age groups.
  2. Constrictive population pyramids is populations that constricted at the bottom.
  3. Stationary population pyramids is populations that show a somewhat equal proportion of the population in each age group.

A population has 1000 individuals. Over a period of 1 year, 500 new individuals are born

Therefore Birth rate = [tex]\frac{number of individuals born}{original population}[/tex]

Birth rate =[tex]\frac{500}{1000}[/tex]

Birth rate =[tex]\frac{1}{2}[/tex]

Thus birth rate is [tex]0.5[/tex]
