In 2017 24/7 Wall St. ranked St. Louis as the 10th most segregated city in America. This ranking came from an average of many different statistics including St. Louis 70.6 Index of dissimilarity and 40% of African American families living in predominantly Black neighborhoods. 

The Index of Dissimilairty is a demographic measurement of how evenely two groups are distributed across a large area. It is one of the most common statistical ways to measure how segregated two groups in an area are. The index ranks from 0 (fully integrated) to 100 (fully segregated). The NAACP calculated St. Louis Index of Dissimilarity score to be 70.6% which is one of the highest in the country. 

The Delmar Divide is a term popularized by a BBC documentary, that is used to describe the stark racial makeup and inequity that exists immediately north and south of Delmar Boulevard in St. Louis. This divide was created purposefully though the use of redlining and zoning laws over decades and the impact of those segregationist practices are still clearly seen today. It is deeply disturbing how different people's lives are who live just across one street from another.

Allen Berry a 70 year old African American who lives just north of the Delmar Divide was interviewed by Next City  and talked about what it is like to live in that area. He says the Delmar Divide "is part of that ingrained, invisible, institutionalized racism kind of thing that you don’t even know it’s there, but it’s there". Allen lives in a neighborhood called The Ville where 60% of the properties are currently vacant. Berry believes this is the direct result of segregationist policies and hopes St. Louis can improve.
