GPWv411： Country identifier grid （ World grid population No 4 . 11 edition ）

World grid population No 4 edition (GPWv4) The first 11 Version in 30 Angular second （ about 1 km ） The grid element is simulated 2000、2005、2010、2015 and 2020 Distribution of global population in . Use the population census and the population distribution of administrative units to allocate the population to cells in proportion . Population input data to 2005 - 2014 What happened in 2010 The most detailed spatial resolution collection available in the annual census results . Input data extrapolation to produce population estimates for each simulation year .

The country identifier grid representation is used to generate GPWv4 Census data sources for population estimates . Pixels with the same value reflect the same data source , Usually a country or region .
