LandScan is a global population database that shows geographical distribution of population at one-kilometer resolution over an average 24 hour period. The LandScan algorithm uses spatial data and imagery analysis technologies and the most up-to-date census data within an administrative boundary. Accurate administrative boundaries are an integral part of the LandScan population distribution modeling process. These population distribution models are tailored to match the data conditions and geographical nature of each individual country and region. (Updated annually)
