Set data ini berisi estimasi jumlah orang per sel petak 30 detik busur, yang konsisten dengan sensus nasional dan catatan kependudukan terkait distribusi spasial relatif, tetapi disesuaikan agar sesuai dengan total negara dalam Revisi 2015 UN World Population Prospects.
Ada satu gambar untuk setiap tahun yang dimodelkan.
Gridded Population of World Version 4 (GPWv4), Revision 11 memodelkan distribusi populasi manusia global untuk tahun 2000, 2005, 2010, 2015, dan 2020 pada sel petak 30 detik busur (sekitar 1 km). Populasi didistribusikan ke sel menggunakan alokasi proporsional populasi dari sensus dan unit administratif. Data input populasi dikumpulkan pada resolusi spasial paling detail yang tersedia dari hasil sensus putaran 2010, yang dilakukan antara tahun 2005 dan 2014. Data input diekstrapolasi untuk menghasilkan estimasi populasi untuk setiap tahun yang dimodelkan.
