Statistics from the 2000 United States Census, adjusted to include the second tier of States west of the Mississippi, show that, under that definition, the West would have a population of 91,457,662, including 1,611,447 Indians, or 1.8% of the total, and 22,377,288 Hispanics (the majority Mexican), or 24.5% of the total. Indians comprise 0.9% of all Americans, and Hispanics, 12.5%. Asians, important from the very beginning in the history of the West, totaled 5,161,446, or 5.6%, with most living in the Far West. African-Americans, totaled 5,929,968, or 6.5%—lower than the national proportion (12.8%). The highest concentrations (12%) of black residents in the West are found in Texas—which is also considered a Southern state—and in California.

The West is still one of the most sparsely settled areas in the United States with 49.5 inhabitants per square mile (19/km²). Only Texas with 78.0 inhabitants/sq mi.

As a result of the various periods of rapid growth, many new residents were immigrants who were seeking to make a new start after previous histories of either personal failure or hostilities developed in their previous communities. With these and other migrants who harbored more commercial goals in the opening country, the area developed a strong ethos of self-determinism and individual freedom, as communities were created whose residents shared no prior connection or common set of ideals and allegiances. The open land of the region allowed residents to live at a much greater distance from neighbors than had been possible in eastern cities, and an ethic of tolerance for the different values and goals of other residents developed. California's state constitutions (in both 1849 and 1879) were largely drafted by groups which sought a strong emphasis on individual property rights and personal freedom, arguably at the expense of ideals tending toward civic community.
