Hull House Maps and Papers, published in 1895 by Florence Kelly and some of her colleagues, depict statistical visualizations relating to the settlement of the Hull House. Florence Kelley was a pioneer in social reform. Kelley lived in Chicago from 1891 until 1899, leading and participating in a variety of projects including a wage and ethnicity census of the slums and tenements in Chicago; the reporting of cases and contagion in the smallpox epidemic of 1893; the enforcement of the universal primary education laws, and enforcing the provisions of the Illinois Factory Inspections Law of 1893. Hull House Maps and Papers is her most well-known work and represents years of research. This section contains re-creations of two maps from the project.
