Out of the following which one cannot be categorised under 'Preventive checks' ?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Famines
According to Malthusian theory, checks on population growth are of two types:
-
Preventive checks – These are voluntary methods to limit population growth . Examples include: Postponing marriage, celibacy, Use of contraceptives
-
Positive checks – These increase the death rate. Examples include: Famines, Diseases, Wars
Famines, being an involuntary and destructive force that increases mortality, fall under positive checks, not preventive checks.
