Demographics Along the Colorado River (U.S. Census Data)

Based on U.S. Census Bureau data for counties bordering the Colorado River, the racial/ethnic composition is:

• Hispanic or Latino: 45.8%
• White (non-Hispanic): 41.2%
• Two or more races: 5.5%
• Black or African American: 4.5%
• Native American: 2.1%
• Asian: 2.0%
• Some other race: 1.9%

Note: This aggregates county-level data along the river's U.S. course. Demographic patterns vary sharply by segment—upper basin (Colorado, Utah) is predominantly White; lower basin (Arizona, Nevada, California) shows strong Hispanic majorities in many counties. Tribal nations (Navajo, Hopi, Hualapai, Cocopah, Quechan, others) hold sovereign lands along the river with distinct demographic profiles not fully captured by county aggregates.
