'Invisible Womentakes on the neglected topic ofwhat we don'tknow - and why. The result is a powerful, important and eye-opening analysis of the gender politics of knowledge and ignorance. With examples from technology to natural disasters, this is an original and timely reminder of why we need women in the leadership of the institutions that shape every aspect of our lives.' Cordelia FineYou've heard all about the Gender Pay Gap... Welcome to the Gender Data GapOur world is largely built for and by men, in a system that can ignore half the population. This book will tell you how and why this mattersIn her new book, Invisible Women, award-winning campaigner and writer Caroline Criado Perez shows us how, in a world largely built for and by men, we are systematically ignoring half the population. She exposes the gender data gap - a gap in our knowledge that is at the root of perpetual, systemic discrimination against women, and that has created a pervasive but invisible bias with a profound effect on women?s lives.Caroline brings together for the first time an impressive range of case studies, stories and new research from across the world that illustrate the hidden ways in which women are excluded from the very building blocks of the world we live in, and the impact this has on their health and wellbeing. From government policy and medical research, to technology, workplaces, urban planning and the media - Invisible Womenexposes the biased data that excludes women. In making the case for change, this powerful and provocative book will make you see the world anew.
