I found this archive recently and it contains images of Charles Booths handwritten notes whilst he walked the area gather the data for his poverty map of late Victorian London. In this example he walks a loop starting at Choumert Road, heads up to Denmark Hill, Red Post Hill, East Dulwich Grove, Goose Green and Adys Road. You can access other walks he did in the area using the drop-down in the top RHS of the screen. http://booth.lse.ac.uk/notebooks/b375/jpg/23.html The colours he refers to are his classification: BLACK: Lowest class. Vicious, semi-criminal. DARK BLUE: Very poor, casual. Chronic want. LIGHT BLUE: Poor. 18s. to 21s. a week for a moderate family PURPLE: Mixed. Some comfortable others poor PINK: Fairly comfortable. Good ordinary earnings. RED: Middle class. Well-to-do. YELLOW: Upper-middle and Upper classes. Wealthy.
