Imagine you are a sociologist interested in the living conditions of marginalized communities today. Based on DuBois's methodology in 'The Philadelphia Negro,' which approach would best help you understand the current social and economic challenges faced by these communities?

To understand the living conditions of marginalized communities today, using DuBois's methodology from 'The Philadelphia Negro' would be very effective. DuBois combined detailed observations with statistical analysis to explore the social issues faced by Black communities in Philadelphia. This approach involves not just looking at numbers but also engaging directly with people in these communities to hear their stories and experiences. For example, if you were studying a neighborhood with high unemployment, you could gather data on job loss while also interviewing residents about their challenges in finding work. By blending quantitative data with qualitative insights, you can gain a deeper understanding of the complex social and economic challenges these communities face today.
