Gridded Population of the World, 2010

<div style='text-align: justify;'><span style='line-height: 1.38461538461538;'>This map comes from a preliminary release of the Gridded Population of the World, Version 4 (GPWv4). GPWv4 is a gridded data product that depicts global population data from the 2010 round of Population and Housing Censuses at a scale and extent sufficient to demonstrate the spatial relationship between human populations and the environment across the globe. This population grid provides globally-consistent and spatially-explicit data for use in research, policy making, and communications and is compatible with data sets from social, economic, and Earth science fields.</span></div><div style='text-align: justify;'><span style='line-height: 1.38461538461538;'><br /></span></div><div>GPWv4 is constructed from national or subnational input areal units of varying resolutions. The native grid cell size is 30 arc-seconds, or ~1 km at the equator. Separate grids are available for population count, population density, estimated land area, and data quality indicators.</div><div><br /></div><div>The full GPWv4 data collection will consist of population estimates for the years 2000, 2005, 2010, 2015, and 2020, and will include grids for estimates of total population, age, sex, and urban/rural status. However, this preliminary release consists only of total population estimates for the year 2010. This data is being released now to allow users early access to the population grids.</div><div><br /></div><div>Source: <a href='http://beta.www.ciesin.columbia.edu/data/gpw-v4/' style='line-height: 1.38461538461538;' target='_blank'>Columbia University, CIESIN</a></div>
