stub freeway formerly part of I-96 that continued out to I-275 became part of M-102. This extension to M-102 was reversed in October 1994 when M-5 was extended northwesterly along Grand River Avenue, the freeway and up the Haggerty Connector north of I-96 in Novi, replacing part of M-102 in the process. Cultural impact Racial and economic divide The road has long served as a de facto cultural dividing line between the predominantly poor black city and its wealthier, predominantly white northern suburbs. The perception of 8 Mile as the chief dividing line between racial groups and classes persists, in part because the suburban counties of Oakland and Macomb remain, on the whole, significantly whiter and more prosperous than the city of Detroit. However, in recent years increasing numbers of whites have moved into Detroit, especially around the downtown area, and other neighborhoods in the region have become more ethnically diverse as well. According to the 2000 U.S. Census, the median family income for the city of Detroit, whose population was 81.55% African-American, was $33,853, and 26.1% of the population lived below the poverty line. By contrast, the median family income for Oakland County, whose population was 82.75% white, was $75,540, and only 5.5% of residents lived below the poverty line. These results were compiled into an Index of Dissimilarity of 85.9 by researchers with Brown University and Florida State University, the highest score for a metropolitan area in the United States. After the 2010 Census, the index was computed as 79.6, which was a "substantial decline" in the words of the study's authors. In surveying 8 Mile Road is also known as Base Line Road, for it was used to set the baseline for the Public Land Survey System in Michigan. The system helped bring order to county boundaries, which had often been set in other states by geographic markers such as rivers, hills, and trees, and were therefore rather irregular. Today, the baseline forms the northern or southern boundary of many southern Michigan counties. In media Tupac Shakur, Tim Roth, and Thandiwe Newton form the fictitious musical act Eight Mile Road in the 1997 film Gridlock'd, which is set in Detroit. The movie 8 Mile, starring Detroit-area hip hop artist Eminem, who lived near 8 Mile as a child, as well as his songs "Lose Yourself" and "8 Mile", take their names and cultural subject matter from the
