Invisible Women: Data Bias in a World Designed for Men is a 2019 book by British feminist writer and activist Caroline Criado Perez. Criado Perez is known for her successful campaign to feature a woman on the British 10-pound banknote, and she was appointed an Officer of the Order of the British Empire in 2015 for her work toward gender equality.
Invisible Women explores how in a world largely built by men, for men, systemic gender discrimination has resulted in half the population being unaccounted for or ignored.
