Most Densely Populated Cities
This ranking highlights cities where the highest number of people live within each square kilometer of official administrative area. Density is calculated as population divided by geographic area — a simple ratio that reveals how tightly packed urban life can be, from megacity cores to compact historic centers.
Key Insights
Before exploring the rankings, here are some important points about urban population density:
- Density vs Population: A city can be very populous yet spread out — density measures how concentrated that population is within official boundaries
- Boundary Definitions Matter: Administrative city limits vary by country; a compact city proper can rank far above a sprawling metropolitan region
- Asian & Global Leaders: South and Southeast Asian cities often dominate density lists, but European and Latin American capitals also rank highly
- Planning & Infrastructure: High density shapes transit systems, housing, and public services in fundamentally different ways than low-density sprawl
Fascinating Insights from the Data
- Manila's Extreme Density: Manila frequently tops global density lists with over 40,000 people per km² within its city proper boundaries
- South Asian Megacities: Kolkata, Karachi, Dhaka, and Mumbai combine enormous populations with relatively compact administrative areas
- European Compactness: Paris and Barcelona achieve high density through historic urban cores and limited geographic expansion
- Density vs Area Rankings: Cities that rank largest by area — like Hulunbuir or Anchorage — often have very low population density
- Island & City-States: Hong Kong and Singapore achieve high overall density despite including less-developed districts and green space

Understanding Density Rankings
Population density rankings depend heavily on how "city" is defined. Our figures use official administrative boundaries, but area and population inputs may differ from other ranking hubs on this site:
- The Formula: Density = total population ÷ administrative area (people per km²)
- Administrative vs Metropolitan: We use official city limits, not broader metropolitan or urban agglomeration boundaries
- Approximate Figures: Population and area estimates vary by source and year; rankings are illustrative and may shift with boundary changes
- Compare Visually: Density numbers alone do not show shape or layout — use our map tool to see how boundaries compare

Methodology & Data Sources
Density figures on this page are derived by dividing estimated population by official administrative area. Both inputs depend on boundary definitions that differ across countries, so treat rankings as approximate and comparative rather than precise official statistics.
- 📊 Data Sources: Population estimates draw on national census data, United Nations urban statistics, and verified demographic databases. Area figures use official administrative boundaries from government geographic agencies and OpenStreetMap. Boundary choices and source years may differ from our largest-cities and population rankings, so area values are not guaranteed to match across hubs.
- 🔄 Calculation Methodology: Density = population ÷ administrative area (people/km²). We prioritize city-proper or official municipal boundaries over metropolitan regions so rankings reflect compact urban cores where possible. Area calculations account for Earth's curvature using the same methods as our geographic size comparisons.
- ⚠️ Limitations & Considerations: Figures are illustrative and approximate — sources and boundary years differ. A city that annexes rural land will see density drop even if the urban core is unchanged. Rankings exclude some micro-municipalities and special administrative units. Water bodies and uninhabited land within boundaries affect both area and density. For deeper context, see our population density explainer article.
