While many city neighborhoods have diversified greatly between 1970 and 2010, large sections of East and West Baltimore remain segregated. Meanwhile, the suburbs have gotten much more diverse, particularly in the Washington region.
Diversity is calculated using an index that shows the percentage chance that any two people in a given census tract will be of different races or ethnicities. Lighter areas on the maps are more segregated, and darker areas are more integrated.

*Some areas in Maryland contain no data in the 1970 census map. In 1970, the census bureau only collected tract-level data for areas that were in metropolitan statistical areas or for selected counties within a state.
