If natural increase is positive but net migration is highly negative what may happen to total population?

Answer and explanation

Correct answer: Total population may decline

Answer: B, total population may decline. Natural increase is positive when births exceed deaths. However, total population change is not determined by natural increase alone; it also includes net migration. Net migration is positive when arrivals exceed departures and negative when departures exceed arrivals. If the negative migration amount is larger than the positive natural increase, the combined total becomes negative. For example, a natural increase of 500 and net migration of −800 gives a total change of −300, so the population declines. A is wrong because positive natural increase can be outweighed by large out-migration. B is correct because it recognises this possibility. C is meaningless because population and area are different quantities. D is wrong because migration directly changes the number of residents. Memory cue: add signed components, not just positive ones.
