Abstract
How the spread of Gentrification in Downtown Detroit is affecting how Black-Owned Businesses (BoBs) are disproportionally displaced compared to the rising trend of non-Black-Owned Businesses. The goal is to use CartoDB to analyze this question based on data from the City of Detroit Open Data Portal and the non-profit organization Data Driven Detroit (D3). The outcome is to see if gentrification is genuinely to blame or are there other underlying reasons.
Introduction
There is much information on Detroit before and during the bankruptcy. The City of Detroit has gone through a lot; however, it looks like the city is resurging strongly. Based on data from the Detroit Regional Chamber of Commerce, it would seem that Detroit is one of the cities in which to live. Although this being the 8th largest city in the nation, the population is trending in the negative.

As mentioned before the cost of living in the Detroit metro area is at 95.1 percent, which means that Detroit is 4.9 percent below the national average. Compared with other major metropolitan areas throughout the United States, Detroit is a very affordable place to live that is a bargain for a significant Metropolitan Area.

With this information presented before you, it helps put into context the origin of my research, its focus, and yes highlight that there is abundant data regarding the resurgence of Detroit. However, you cannot read any blog, news and, financial magazine without them focusing on how white millennials are “invading” Detroit, in particular, the Downtown area, which is currently the hub of Detroit’s innovative re-birth. I did not want to duplicate research that was done before or is ongoing, and I was pleasantly surprised that there was no comprehensive work in progress or datasets that look to answer my question. I had to creatively restructure my approach as to how I would present/visualize the results.
Of course, there were plenty of maps that interactively showcased that there was little to no gentrification and there was data that provided proof that as the population of Detroit continued to decrease the ration of native-born Blacks remained high compared to the other races living the Motor City. However, there was little to no data with the spatial resolution to showcase the general trend of the upswing in Black-Owned Businesses. Actually, from the Census’ Survey of Business Owners, it has shown that from 2007 to 2012 that there has been a sharp increase in minority businesses in particular Black-Owned Business.
Methodology
My original process was to cover a five (5) year period that included Detroit before, during, and after the now-infamous bankruptcy. Also, to visualize the trend using CartoDB to present the data and the outcome dynamically. The challenge is that I found enough data broken down showing the five (5) year comparison; however, it proved very difficult to be able to geocode the data so that we could accurately visualize the upward trend of Black ownership. The various data I found tend to have different components necessary to present the data cartographically accurately. I did come across in my research different SBO or Economic data. However, it all seems impossible that each data block was missing key attributes to be able to combine the appropriate geocode necessary for mapping. Therefore, I present my results not through the cartographic process, but table form.
City | State | NAICS code | Meaning of NAICS code | Race code | Meaning of Race code | Year | Number of firms with or without paid employees |
Detroit | Michigan | 0 | Total for all sectors | 40 | Black or African American | 2012 | 47640 |
Detroit | Michigan | 0 | Total for all sectors | 30 | White | 2012 | 11395 |
Detroit | Michigan | 0 | Total for all sectors | 40 | Black or African American | 2007 | 32483 |
Detroit | Michigan | 0 | Total for all sectors | 30 | White | 2007 | 15668 |

Conclusion
From all the data, it would seem that the rate of gentrification is not a factor for the growth of Black-Own Businesses. As it stands until I can get the data with the spatial resolution, I would be remiss to have a map that isn’t interactive, and that speaks to the level of poverty and in essence present via CartoDB that currently, gentrification is not a factor in stemming the growth of Black-Owned Businesses.
Here is a link to my map called Detroit by the Numbers that shows the level of poverty in the various zip codes, 48201and 48226 in Detroit’s Business District (the Downtown area). I would say that between the two zip codes that we have a pretty balanced area. Hover over the areas, and you can see what is mean by my statement. My goal is to continue and refine this project going forward into a true GIS format.
