Question

Which of the following formula correctly defines natality?

(a) Natality = \(\frac{Number \, of \, deaths \, per \, year}{Mid-year \, population}\) x 1000

(b) Natality = \(\frac{Number \, of \, births \, per \, year}{Mid-year \, population}\) x 1000

(c) Natality = \(\frac{Number \, of \, births + Number \, of \, deaths}{Mid-year \, population}\) x 1000

(d) Natality = Births – Deaths x 1000

I have been asked this question in quiz.

The origin of the question is Population Growth in chapter Organisms and Populations of Biology – Class 12

Answer 1

The correct choice is (b) Natality = \(\frac{Number \, of \, births \, per \, year}{Mid-year \, population}\) x 1000

Explanation: The natality is also known as the birth rate. It is the number of individuals born in a population at a specific time. For humans, it is described as a number of individuals born per 1000 of the population per year.
