Looking at Population Density

Population density varies across the U.S., with generally higher values in the east and lower values in the west. In this image, rural areas with densities less than one person per square km are shaded tan; urban areas having more than 1000 persons per square km are shaded in red.

Combining Census and Satellite Data

Gridded census data, like population density, can easily be combined with satellite imagery and Earth science data to better understand where people are vulnerable to natural hazards such as hurricanes, earthquakes, and floods.


NASA's data policy ensures that all NASA data are available fully, openly, and without restrictions. Here's what this means to you.


The Earth Observing System Data and Information System is a key core capability in NASA’s Earth Science Data Systems Program. It provides end-to-end capabilities for managing NASA’s Earth science data from various sources—satellites, aircraft, field measurements, and various other programs.
