Introduction

Population-resource relationship describes how the number of people in an area relates to natural resources like land, water, and food.

Types of Population Scenarios

Scenario Definition Consequences Example
Underpopulation Resources > population; excess resources compared to people Resources underutilized, slow growth Large land but low population (e.g., Canada, Australia) 
Overpopulation Population > resources; too many people for available resources Resource depletion, lower quality of life Densely populated cities using all resources (e.g., some areas of India, China) 
Optimum Population Balance: population and resources in harmony Highest efficiency, sustainability Well-managed nations, regions with balance between people and resources
Maharashtra State Board: Class 11

Real-Life Application

Suppose a village has enough water and farmland for 100 families.

  • If only 40 families live there (underpopulation), much of the land may stay unused.
  • If 200 families move in (overpopulation), water and food may run out quickly.
  • If 100 families live there (optimum), everyone gets enough resources, and the village runs efficiently.

Key Point Summary

  • Underpopulation = not enough people to use resources fully.
  • Overpopulation = too many people for available resources.
  • Optimum population = ideal balance, maximised welfare and sustainability.
