What it means

How many people live in the built-up city as a whole, regardless of municipal borders.

How it is calculated

Satellite maps of buildings and census data are combined into a 1 km grid; the continuous dense area of at least 50,000 people is the urban centre. Every five years from 1975; 2030 is a projection.
