Find a city with more residents per square kilometre.
Test your knowledge of City population density in a Peakle trivia climb. Each answer must be higher than the last, using people/km² as the scale.
Play City population densityUnderstand the measure
Peakle turns City population density from a one-off fact question into a progressive comparison challenge. Population density turns city comparison into a compactness challenge, where a smaller city can rank above a much larger one if more residents share each unit of land. You can begin with any valid answer, then keep choosing a larger item on the published scale; familiar and surprising entries together test how well you understand the category.
This route uses people/km² as its comparison scale and keeps the 2025 UN DESA · World Urbanization Prospects 2025 dataset visible so the rules can be checked. Density is a relationship between population and area, so boundary choice affects both parts of the calculation. The route uses the published density value rather than asking you to recompute it. Values are shown at the precision used by the source, so the goal is to compare published records consistently rather than guess at extra decimals.
A reliable approach is to choose a comfortable starting point, reserve obvious high-value answers for later, and watch for near-ties. Look for compact urban boundaries and places known for intense development. Do not confuse a crowded downtown with the density of the full administrative city. If two candidates seem close, use the displayed value and source definition instead of relying on memory; one invalid step ends the climb, but every run teaches you more about the shape of the dataset.
The route
Pick an item from the answer bank to set your starting point.
Every next answer must be larger than the one before it on the published scale.
One wrong, repeated, or equal answer ends the climb and records your score.
Evidence behind the climb
This route uses UN DESA · World Urbanization Prospects 2025 data from 2025. The question asks you to compare City population density using the published values.
Before you climb
Choose an answer, then keep choosing a larger value measured in people/km². The goal is to build the longest valid chain you can.

Can a smaller city be denser than a larger one? Yes. Density is about residents per area, not total residents or total city size alone.
