Where do most people in the Rocky Mountains live?

In the Rocky Mountains, human settlement is widespread, but the population is primarily concentrated in specific locations rather than being evenly distributed across the rugged terrain. Most people live in urban areas situated at the base of the mountains, along railways, or within river valleys.1

For example, in the Colorado region, the population is heavily clustered in the metropolitan areas of the Colorado Piedmont—a corridor along the mountain front that includes cities such as Denver, Boulder, Colorado Springs, and Fort Collins. In contrast, the actual mountain and plateau counties have much lower population densities due to challenging terrain, isolation, and severe winters, with rural residents typically settling in restricted mountain valleys where ranching and irrigation farming are viable.23
