The Hispanic population is concentrated on the south side, while African Americans are concentrated in the north. The white population is in the majority in only two census tracts: the downtown area and the far northwest. Many areas in the middle of the city, in Asylum Hill, and in West End, have a significant white population. More than three-quarters (77%) of the Hispanic population was Puerto Rican (with more than half born on the island of Puerto Rico) and fully 33.7% of all Hartford residents claimed Puerto Rican heritage. This is the second-largest concentration of Puerto Ricans in the Northeast, behind only Holyoke, Massachusetts, approximately to the north along the Connecticut River.
