How a plot and a map can tell you how much is Detroit racially segregated
We all know Detroit is bankrupt and decayed. We do also know Detroit is racially segregated even though it is half century since racial segregation officially ended in the United States. Yet, I doubt most people know how hard and deep is this segregation.
I took percent of African Americans in each census block in Detroit metro (by which I mean Wayne, Oakland and Macomb counties) and confront it with median household income. Here’s the result:
It basically looks like I took data from two different continents and combined it into one dataset.
There are two shocking things you can see on this scatter plot:
1. Black neighborhoods tend to be more consolidated by income, i.e. there are no black neighborhoods with very high income and there is a lot black neighborhoods in (much) lower-middle-class income spectrum. Non-black neighborhoods on the other hand can be poor (although that ‘poor’ is actually the black average) and filthy rich and the majority would be considered middle-class.
2. There are literally just a few racially diversified neighborhoods. People in Metro Detroit tend to live either in white-only or black-only neighborhoods.
The latter is, in my opinion, important and scary.
Not-knowing any white or black person, not-having blacks or whites as neighbors certainly will not help in developing a race-blind society. If someone is born and raised in an all-black or all-white area that person obviously do not know much about the other race and therefore use stereotypes on daily basis.
If I was born in a white community I might think of blacks as of criminals and if I was born in a black community I might think of whites as of ruthless rich bastards. If I live in a multiracial community I see joyful and law-abiding blacks as well as whites barely making ends meet.
And here is how does racial division look on a map
(the more red -> the more whites; the more blue -> the more blacks)
As you can see, African Americans are gradually moving North of the infamous 8 Mile Road but Detroit city limits are still extremely visible. Hamtramck is also still clearly visible, though the Polish population was pretty much replaced with Middle-Easterners over last 20 years.
