Population - JRC
People per square km:
5 – 300
This dataset depicts the distribution and density of population, expressed as the number of people per cell, for reference epochs: 1975, 1990, 2000, 2015. Residential population estimates were provided by CIESIN GPW v4. These were disaggregated from census or administrative units to grid cells, informed by the distribution and density of built-up as mapped in the GHSL global layer per corresponding epoch. This dataset was produced in the World Mollweide projection (EPSG:54009).

The GHSL relies on the design and implementation of new spatial data mining technologies allowing to automatically process and extract analytics and knowledge from large amount of heterogeneous data including: global, fine-scale satellite image data streams, census data, and crowd sources or volunteered geographic information sources.
