Notes:

  • The minority population includes all race groups other than White alone, plus all individuals of Hispanic or Latino origin, regardless of race. 
  • Hispanic origin is considered an ethnicity, not a race.
  • Due to changes over time in definitions and questions on race and Hispanic origin, data may not be directly comparable from one decennial census to the next.
