Number, density and population growth in the world
On the 1st of January 2016 the Earth's population reached 7,295,889,256 people, at the same time it is very unevenly distributed.
Information for this study is taken from the official websites of the national statistical agencies, mainly from the census (the most detailed and accurate sources), and then the quality map is compiled.
SEDAC assessed and gave a forecast of the population size and density in 2000, 2005, 2010, 2015, 2020.
All maps are available in vector at the Columbia University website.
It is interesting to compare the number and density of the population on a night photo of the world (light pollution, if you like). NASA has made such a picture in 2012:
However, even more interesting is the dynamics of the population. SEDAC used this data but showed in the form of projections. More demonstrative is a thermal data map by CIA from Wikipedia:
This map allows you to understand why population growth in Africa is a cause for concern.
The main advantage of the NASA projects is that there is a lot of data, and it’s very convenient to use.Digital cartography and GPS navigation 02-11-2016
