The LandScan data set is a worldwide population database compiled on a 30" X 30" arc second latitude/longitude grid (roughly 1 x 1 km). Census counts (at sub-national level) were apportioned to each grid cell based on likelihood coefficients, which are based on proximity to roads, slope, land cover, nighttime lights, and other data sets.
