The 2021 summer scholars team (Ava, Linnea, Victoria & Calyn), used historic census data from 1910-1940 to look at the concentration of Black residents in Ramsey County. The data is organized by enumeration districts — a geographic area that was assigned to a census taker and roughly can be thought of as a neighborhood.

The bar graph shows that in 1910 approximately 1/3 of neighborhoods had no Black residents and by 1940 this had doubled such that fully 2/3 of neighborhoods had no Black residents. This shows that segregation was worsening in Ramsey County over this time period — presumably due to racial covenants and other forms of housing discrimination.This map shows the share of Black residents in each enumeration district in 1940.
