Density of a population (D) is :

Key Points

• D = N (number) / S (space) is the correct formula for the density of a population.
• Population density is defined as the number of individuals per unit area or volume.
• This formula helps in understanding how populated an area is, which can be crucial for planning and resource allocation.

Additional Information

• Population density is an important metric in demographics, urban planning, and environmental studies.
• High population density can lead to overcrowding, strain on resources, and increased pollution.
• Low population density might indicate underutilized resources or a need for infrastructure development.
• It is also used in ecological studies to understand the distribution of species within a habitat.
