U.S. percentage of population illustrating concentration of ethnicity and race by block groups.

The increased gradation ranges represent the ethnic/race population as a percentage of the total population in that block group. For a group to be illustrated, the population of that group must be at least:

• .7% Native American = green
• 3.6% Asian = purple
• 12.1% Black = blue
• 12.5% Hispanic = orange
• 69.1% White, N/H = gray

U.S. Percentage of Population illustrating concentration of Hispanic block groups, 2000.

The increased gradation along the southwestern United States closely resembles the U.S.- Mexico borderline prior to the Treaty of Guadalupe Hidalgo, 1848.
