Characterizing the Demographics Behind the #BlackLivesMatter Movement

摘要

The debates on minority issues are often dominated by or held among the concerned minorities: gender equality debates have often failed to engage men, while those about race fail to engage the dominant group. To test this observation, we study the #BlackLivesMatter movement and hashtag on Twitter - that has emerged and gained traction after a series of events typically involving the death of African-Americans as a result of police brutality - aiming to quantify the population biases across user types (individuals vs. organizations), and (for individuals) across 3 demographics factors (race, gender and age). Our results suggest that more African-Americans engage with the hashtag, and that they are also more active than other demographic groups. We also discuss ethical caveats with broader implications for studies on sensitive topics (e.g. mental health or religion) that focus on users.
