Population spatial distribution data is the data we often use in various researches. Before that, we shared with you the 1km precision population distribution raster dataset from the LandScan platform from 2000 to 2021. The LandScan population dataset was developed by the U.S. Department of Energy's Oak Ridge National Laboratory (ORNL) and provided by East View Cartographic. LandScan uses innovative methods such as GIS and remote sensing, and is the social standard for global population data release. It is the world's most accurate, reliable, geographically-based, global demographic analysis database with distribution models and the best resolution.
On July 1, 2023, the LandScan population data set updated the data for 2022. We downloaded and processed the data and shared it with everyone! In a nutshell, what I share this time is the 2000-2022 population spatial distribution raster data with a precision of 1 km from the LandScan dataset . In addition to downloading the global data, in order to facilitate everyone's use, we also process the data into nationwide data, divided by provinces, and divided by cities, and share them with you!
The following is a detailed introduction of the data:
01Data preview
Let's take the 2022 data as an example to preview:
worldwide data
nationwide data
Province-wide data
Let's take the data of Hubei Province in 2022 as an example to preview:
Let's take the updated 2022 data of Wuhan as an example to preview:
02Data Details
Data resolution:
30 arc seconds (about 1 km)
Data Sources:
https://landscan.ornl.gov
Data Format:
tif
Data coordinate system:
WGS1984
Data unit:
The unit of this data is person. It should be noted that the value of this data represents the number of permanent residents in each grid (the grid area is about 1 km*1 km)! For example, if the value of a grid is 56568, it means that the grid has a permanent population of 56568 people!
