LandScan is a global population database that shows geographical distribution of population at one-kilometer resolution over an average 24 hour period. Most national censuses count populations by measuring where people sleep (or reside) rather than where they work or travel. LandScan integrates daytime movements and collective travel habits into a single measure to produce a better representation of where people are located during an average day. Datasets are available from 2000-2018.
