What is the author's style in All Our Kin: Strategies for Survival in a Black Community by Carol B. Stack?

Stack is writing as an academic sociologist interested in understanding and explaining black poverty. She references studies she completed before writing this project, but the majority of her work is founded upon the three years she spent in the Flats. Conscious of how her attempts to study the community might bias or even invalidate her findings, Stack decided to simply live among them as one of them.
