LandScan Mosaic maps global populations by building use
A new Oak Ridge dataset estimates where people are throughout the day based on how buildings are occupied.
Researchers at the Department of Energy's Oak Ridge National Laboratory have released LandScan Mosaic, a new global population distribution dataset. Unlike traditional censuses that capture where people live, the dataset estimates where people actually are by modeling how buildings are used and occupied throughout the day.
The approach shifts from static residential counts to dynamic patterns of movement, reflecting daily rhythms in homes, workplaces, and other structures. Because the dataset is global, it aims to provide a consistent picture of population presence across countries and regions.
With only one source available, there are no conflicting accounts to compare. The source emphasizes the novelty of using building occupancy models to generate these estimates, positioning LandScan Mosaic as a next-generation resource for researchers and policymakers. Further details on validation methods or specific applications are not included in the source material.
