WHAT IS DENSITY OF POPULATION? EXPLAIN FOUR GEOGRAPHICAL FACTORS INFLUENCING THE DISTRIBUTION OF POPULATION IN THE WORLD.
Density of population: Number of people living in per unit area such as per sq. km. [Ratio between the numbers of people to the size of land]
Following Geographical Factors are responsible:

- Landforms – plain, plateau and mountain
- Climate – temperature, rainfall, no. of frost – free days etc.
- Soil – nature & types
Above four points to be discussed with example.
