What do you mean by birth rate? Explain its formula.

Answer»

Birth rate is calculated by dividing the number of live babies in a particular year by the total population and then multiplying the result by 100 to get percentage figure or by one thousand to get per thousand figure.

birth rate = B/P × 100 or 1000 

where B = births taken place in an year 

P = total population of the year
