The widely distributed 2010-2011 World Resources Report: Decision Making in a Changing Climate includes coastal population estimates from SEDAC′s Population Landscape and Climate Estimates (PLACE) data collection. The data includes both the percentage of and a country′s actual population living within 10 kilometers of a coastline, and is based on SEDAC′s Global Rural-Urban Mapping Project (GRUMP) population data set.
Map of school-age children in earthquake zones illustrates an accompanying article: following the recent earthquakes in China, experts assess school safety and the vulnerability of children to earthquakes.
Map of Pakistan illustrating areas of escalating violence in the Punjab, the country’s most populous province.
An embedded Google Earth client in an article in Nature News shows the population count living within 75 kilometers of each of the world′s nuclear power plants. Population increases with circle size and color, from green (< 0.5 million) to red (> 20 million). The data and analysis were developed by SEDAC.
A typically higher standard of living in urban areas compared to rural ones does not rule out striking disparities within cities. SEDAC data from its Global Poverty Mapping Project is used as the basis for this map. Map 1.2, illustration for Chapter 1--Density, The World Development Report Online 2009.
This interactive map shows the population missing as a result of the Haiti earthquake on January 28, 2010. Thousands of personal reports of loved ones missing were provided to Ireport, and this information was combined with SEDAC population data to create the map.
A map of Burma, based on the SEDAC Gridded Population of the World (GPW) data product, reveals that coastal areas hit hardest by the cyclone in May 2008 were highly populated. (Areas in progressively darker shades of brown represent increased population.)
SEDAC′s GPWv3 and GRUMPv1, along with MODIS and SRTM data, are used in a paper, “Modelling the Distribution of Chickens, Ducks, and Geese in China,” by D.J. Prosser et al, appearing in Agriculture, Ecosystems & Environment. Global concerns over the emergence of zoonotic pandemics emphasize the need for high-resolution population distribution mapping and spatial modelling. Because of a lack of livestock population distribution data in China, modeling the distribution of poultry is critical to studying emerging zoonotic pandemics. GRUMP population density and urban extents are predictor variables in the model in this paper.
In this blog for the Center Environmental and Security Program (ECSP), CIESIN deputy director Marc Levy talks with ECSP director Geoff Dabelko about using the Gridded Population of the World (GPW) data product to aid in combining population and geographic data.
A CNN video newscast refers to a map of the path of Cyclone Nargis and the populations affected, in the worst natural disaster in the recorded history of Burma (Myanmar).
The SEDAC data set Low-elevation Coastal Zone (LECZ) is the basis for a set of national-level indicators of the total area and population in the LECZ circa 2000.

Map of China illustrates an article comparing the location of the Sichuan province earthquakes with population centers in China.
Data and maps compiled by SEDAC and the Center for Hazards and Risk Research are featured in a front-page news article in the New York Times (print version February 25) assessing the vulnerability of buildings in earthquake zones. “Where Shoddy Construction Could Mean Death” shows a map (top) that depicts the predicted number of deaths in Instanbul from a magnitude 7.5 earthquake, depending on the type of construction of the building. The second map (bottom) ranks the vulnerability of other urban areas in earthquake zones with more than one million people.
SEDAC population density data was used in a map of the Haiti earthquake.
A Nature Climate Change article focuses on the milestone of world population passing the seven billion mark and the implications for climate change mitigation and adaptation. Maps featuring SEDAC’s GRUMP data set, describing populations at risk of climate change impacts, are featured on Page 3. The article also features interviews with former SEDAC project scientist Deborah Balk and SEDAC deputy manager Alex de Sherbinin.
SEDAC’s Gridded Population of the World version 3 (GPWv3) dataset is now available through an interactive 3D globe based on WebGL, hosted on Google’s Chrome Experiment site (requires compatible graphics card).
Sensing Our Planet: NASA Earth Science Research Features 2008 features an article on how SEDAC data was used for the 2008 Environmental Performance Index and other environmental assessments; CIESIN’s Marc Levy is interviewed.
A map of SEDAC′s the Human Footprint illustrates the extent to which Africa′s land area is influenced by humans.
An interactive map shows impacts from the recent Haiti earthquake.
Satellite data offer a particularly valuable perspective on PM2—small particles deriving mostly from burning fossil fuels and biomass, which can harm human health—because ground instruments may be unavailable or offer limited information, as is the case in China. With that in mind, researchers at Columbia University’s Earth Institute and Batelle Memorial Institute have developed maps based on satellite data that depict annual PM2.5 exposure in all of China’s provinces.
