What is Population Density?
Population density measures how many people live per unit area. It is a fundamental geographic and demographic statistic used for urban planning, resource allocation, public health, and environmental assessment. Density can be calculated for countries, cities, neighborhoods, or any geographic unit.

📐 Formula
D = P / A
D = population density (persons/km² or /mile²), P = total population, A = area in km² or miles². Also expressed as persons per hectare for urban planning.
📝 Worked Example
Singapore: Population = 5.92 million, Area = 728.6 km²
D = 5,920,000 / 728.6 = 8,124 persons/km²
(One of the highest in the world; compare to Australia: ~3 persons/km²)
📝 How to Use
❓ FAQ
What is arithmetic vs physiological density?
Arithmetic density = people/total area. Physiological density = people/arable land — more meaningful for food security analysis.
Does higher density always mean lower quality of life?
Not necessarily. Dense cities like Singapore and Tokyo have excellent quality of life. Good infrastructure and services can accommodate high density.
