A country records 800000 births and 500000 deaths in one year. Ignoring migration, what is the natural increase?

Answer and explanation

Correct answer: 300000

Natural increase measures the change produced by births and deaths alone. When migration is excluded, it is calculated by subtracting the number of deaths from the number of births: \(\text{natural increase}=\text{births}-\text{deaths}\). Births add people to the population, whereas deaths remove people. Migration would be included separately when calculating total population change.

Here the calculation is \(800000-500000=300000\), or 3 lakh people. Therefore, option B is correct. Adding births and deaths would give 1.3 million, but that does not represent population increase because deaths do not add people. The result is positive because births exceed deaths during the year.
