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.
An open access geospatial data repository for the Pacific Region providing premier geophysical, geodetic, and marine spatial data sets. Developed through collaboration between the GeoScience, Energy and Maritime Division of the Pacific Community (SPC), University of Sydney, Geoscience Australia (GA), and GRID-Arendal.
1) At administrative level 1 these tables do not refer to the National Capital District or to the Autonomous Region of Bougainville. The National Capital District is combined with the Central Province and Bougainville is combined with the North Solomons province.
In urban areas, responsibility for providing piped water and sewerage services in the nation’s capital, Port Moresby, lies with Eda Ranu, and for the remaining provincial and district towns with Water PNG (formerly the PNG Water Board). Service provision to these areas are estimated to be 89% access to safe water (little change from 87% in 1990), and 57% access to safe sanitation (down from 89% in 1990)1. Access to services in urban areas struggle to keep up in the face of rapid urban population expansion.
A recently published paper, titled “Coastal proximity of populations in 22 Pacific Island Countries and Territories” details the methodology used to undertake the analysis and presents the findings. **Purpose** * This analysis aims to estimate populations settled in coastal areas in 22 Pacific Island Countries and Territories (PICTS) using the data currently available. In addition to the coastal population estimates, the study compares the results obtained from the use of national population datasets (census) with those derived from the use of global population grids.
