The graph illustrates the Malthusian theory of population growth.

Definition

Noun: * Malthusian theory: The economic and demographic theory proposed by Thomas Malthus, which posits that population tends to increase at a geometric (exponential) rate, while the means of subsistence (food production) increases only at an arithmetic (linear) rate. This fundamental imbalance, if unchecked by preventive measures like moral restraint or positive checks like famine, disease, or war, would inevitably lead to widespread poverty and misery.

Usage Examples

• Noun:
  • The Malthusian theory was highly influential in 19th-century economic thought.
  • Critics of the Malthusian theory often point to technological advances in agriculture that have increased food production beyond Malthus's predictions.
  • The concept of carrying capacity in ecology is sometimes linked to the principles of the Malthusian theory.

Advanced Usage

• "To have Malthusian concerns/predictions": To express worries or make forecasts based on the idea that population growth will eventually outstrip resources.
  • Environmentalists sometimes express Malthusian concerns about the sustainability of current population levels.
• "A Malthusian trap": A situation where population growth prevents sustained increases in per-capita income, keeping a society in a state of poverty.
  • Some historians argue that pre-industrial societies were caught in a Malthusian trap.

Variants and Related Words
