This online interactive atlas is complimented by both a hard copy and e-copy. The Marine Atlas for the Tonga compiles over a hundred datasets from countless data providers and for the first time makes marine and coastal information accessible and usable as data layers and as raw data. The Tonga Marine Atlas was prepared by the Marine and Coastal Biodiversity Management in Pacific Island Countries (MACBIO) project

The Gridded Population of the World, Version 4 (GPWv4): Population Density, Revision 11 consists of estimates of human population density (number of persons per square kilometer) based on counts consistent with national censuses and population registers, for the years 2000, 2005, 2010, 2015, and 2020. A proportional allocation gridding algorithm, utilizing approximately 13.5 million national and sub-national administrative units, was used to assign population counts to 30 arc-second grid cells.
