The exact breakdown varies by classification:
Non-Hispanic White Women: Account for roughly 30% to 31% of the total U.S. population.
White Women (including Hispanic/Latino): Because the U.S. Census Bureau classifies Hispanic/Latino as an ethnicity rather than a race, women who identify as white (both non-Hispanic and Hispanic) make up about 52% to 55% of the female population.
