Natality and Population Growth — NEET Biology
✅ Asked in NEET 2018Natality refers to: (NEET 2018)
Natality refers to: (NEET 2018)
Answer & NCERT explanation
Correct answer: B — Birth rate
Natality is the technical term for birth rate in population ecology. It refers to the number of births per unit time in a population. Death rate is called mortality. Immigration and emigration refer to movement of individuals into and out of habitats respectively, as per NCERT population ecology chapter.

Natality refers to the number of births during a given period in the population that are added to the initial density.
Natality is the number of new individuals added to a population through birth during a specific time period. It directly increases population density and is a key factor in population dynamics. Students often confuse natality with fertility rate or mistake it as only referring to human births, when it applies to all organisms. To answer correctly, remember that natality measures actual births added to the population, not the reproductive potential. It's paired with mortality to determine net population change, making it fundamental to ecological calculations tested in NEET.
