Question 5

Population

Given that
B = Births
D = Deaths
X = Emigrants
M = Immigrants
The population of a country over a period of time will rise if

  1. A.B = D and X > M
  2. B.B − D = O and M > X
  3. C.D − B = O and M = X
  4. D.X > M and D > B.
Show the answer and explanation

Answer: B (B − D = O and M > X)

Explanation

If births equal deaths, natural increase is zero, so the population rises only if more people come in (M) than leave (X).
