Proportion of Desert Areas Compared to Total Area of the United States

The total area of the United States is about 9,833,517 km², and

the total area of the major deserts mentioned above is about 1,310,000 km². From this, we can calculate:

  • Proportion of desert areas: about 13.3%

This figure considers only the major deserts, and if we include semi-desert areas or other arid regions, it can be seen that desert and semi-desert environments occupy about 30% of the total area of the United States.

These desert regions provide unique ecosystems and natural landscapes, playing important roles in tourism, research, and ecological conservation.
