Description
Understanding how human population is spread out across the Earth's surface is an important part of many types of research, and it is especially important for studying the planet's supply of and human demand for natural resources like freshwater, forest products, or good farmland.
This map is broken up into grids showing number of people per square kilometer. The most densely populated areas are bright red; these include large cities all over the world. Another obvious population pattern is the big difference in population between Earth's most populated countries - China and India - and other countries.
Many countries conduct population censuses, but they do not all collect data at the same spatial scale or with the same frequency. To combine these different national population estimates on the same map, scientists sometimes have to estimate the population in one place in a country based on the data in a nearby place, or estimate population density for a recent date based on older data, using models that predict how a population would likely have changed over time. This map is based on census data available in 2000 and uses estimates when necessary to fill in missing or incomplete data.
