In Brazil, inequalities are visually represented in its favelas. These neighborhoods are usually comprised of low-income informal settlements neglected by governments and often forgotten by mainstream media. The pervasive nature of information and communications technology (ICT) has brought new ways to produce news content in the media industry, giving voice to these communities. Thus, small, alternative, community, or nonmainstream media became a vital terrain of opposition activism. Drawing on user participation, collaboration, and data journalism theories, this article analyzes three alternative media organizations (Agência Mural, data_labe, and Favela em Pauta), which proposed producing data-driven content by, for, and about favelas through a mixed-method research design. Results show that four contributing factors tend to help these organizations to produce data stories despite these challenges: citizen participation, activism, collaboration, and humanizing data. The article concludes by demonstrating how elements developed in these initiatives and presents an agenda for future research.
