Tri-Taylor consists of the area bordered by Harrison Street to the North, the diagonal Ogden Avenue to the East, Roosevelt Road on the south and Western Avenue on the west. It is shaped vaguely like a triangle and hence "Tri-Taylor." The neighborhood is traditionally an extension of the Little Italy neighborhood to its east, although it has consistently been one of the most diverse 'neighborhoods' in Chicago as it was situated on the borders of heavily African American, Irish, Hispanic, and Italian areas. Recently it has been composed mostly of Mexican-Americans and students from nearby the University of Illinois at Chicago (UIC). The neighborhood is also home to the Chicago Technology Park research center as well as the West Side Center for Disease Control, the office for the Medical Examiner of Cook County, and the Chicago Hope Academy (a private high school which opened in 2005).
