Population Density of Keriri Island small area forecast

Population Density Explained

Population density is the number of people per square kilometre of land. Place Forecast computes it as population divided by land area.

Density is a fair way to compare places of different size. A small town and a big city can have the same density but very different populations.

Estimated figures come from the Estimated Resident Population. Future density is projected using the cohort-component method. Only the population changes over time. The land area stays fixed within an ASGS edition.

A few things matter when you read density:

  • Density is not the same as crowding. Crowding is about how many people share a home. Density is about how people spread over land. A place can be dense but not crowded.
  • The land area is gross. It includes parks, water, and unused land. Places with lots of unused land look less dense than they feel.
  • In remote places the population estimate is less certain.

The comparison page opens on a Dorling cartogram by default. A plain map can mislead for density. Large areas draw the eye. A cartogram sizes each area by value, not by land area, so the eye reads the rate, not the shape. You can switch to a Demers cartogram or a plain choropleth map from the toolbox.
