A new way of thinking about data science and data ethics that is informed by the ideas of intersectional feminism. Today, data science is a form of power. It has been used to expose injustice, improve health outcomes, and topple governments. But it has also been used to discriminate, police, and surveil. This potential for good, on the one hand, and harm, on the other, makes it essential to ask: Data science by whom? Data science for whom? Data science with whose interests in mind? The narratives around big data and data science are overwhelmingly white, male, and techno-heroic. In Data Feminism, Catherine D'Ignazio and Lauren Klein present a new way of thinking about data science and data ethics-one that is informed by intersectional feminist thought. Illustrating data feminism in action, D'Ignazio and Klein show how challenges to the male/female binary can help challenge other hierarchical (and empirically wrong) classification systems. They explain how, for example, an understanding of emotion can expand our ideas about effective data visualization, and how the concept of invisible labor can expose the significant human efforts required by our automated systems. And they show why the data never, ever "speak for themselves." Data Feminism offers strategies for data scientists seeking to learn how feminism can help them work toward justice, and for feminists who want to focus their efforts on the growing field of data science. But Data Feminism is about much more than gender. It is about power, about who has it and who doesn't, and about how those differentials of power can be challenged and changed.

At first glance, contemporary popular culture, filled with bleak images of the future, seems to have given up on the possibility of positive collective change. Below the surface, however, alternative culture is rife with artist-led projects, activist movements, and subcultural communities of interest that seek to spark the collective imagination and to encourage hunger for alternatives. More playfully self-conscious than past utopian movements, today's are often whimsical or ironic, but are still entirely earnest. Artists invite us to re-author city maps, or archive individual ideas for the future, while maker collectives urge us to rethink our relationship to consumer goods. All seem to have grown out of a similar do-it-yourself ethos and alternative culture. One of the central conflicts informing these case studies is that while it remains immensely difficult to envision anything outside of the current system of consumer capitalism, there is nevertheless a powerful desire to take it apart in piecemeal ways. We see the longing for new social and political narratives, new forms of communion and sociability, and new imaginings of the possible, longings that are currently unmet by mainstream culture, but that are taking expression in myriad ways at the local level. Taken as a whole, this collection examines what our grand ideals and playful daydreams tell us about ourselves.
