Map: Detroit General Population Distribution 1909

Screen Shot 2018-09-11 at 9.29.05 PM.png

This fun colored map was included in the 1913 Detroit Recreation Survey put together on behalf of The Detroit Board of Commerce.

Oddly enough the data generated from this map came from an appraisal survey completed for the Detroit United Railway company. Not surprisingly, the railway would need to know where people were living in order to plan and project their next rail investment. We now have a Census Bureau completing regular surveys, however if we see further cuts to the Census, there very well may be a corporation that starts funding it.

Map: Opportunity Atlas in Detroit

Chetty_opp_index.png

Another “Opportunity Atlas” has been release by Raj Chetty, John Friedman, and Nathaniel Hendren in conjunction with the Census Bureau’s Maggie R. Jones and Sonya R. Porter through Opportunity Insights, a partnership between economists at Harvard University and Brown University. The atlas is already being used by the Kresge Foundation to drive decision-making.

This opportunity atlas/index joins others crafted by the Kirwan Institute and the national Opportunity Index all driven by use of Census data. The difference with the Opportunity Atlas is that it attempts to make future predictions based on the available Census data.

From the CityLab article:

The earlier a child moves to an above-average neighborhood, the greater the gain. On average, a family that moves from a neighborhood that has below-average opportunity to one that’s above-average at the time of a child’s birth can increase that child’s lifetime earnings as an adult by $200,000, and dramatically decreases the likelihood of incarceration, according to the new research. That’s $9,000 more per year than someone who moves in their 20s.

Map: Social Connectedness in Detroit 2016

Screen Shot 2018-09-19 at 4.48.49 PM

Detroit and Wayne County’s “social connectedness” show strong ties within the Mitten as well as some peripheral connections to the south, Mississippi, Alabama, and Georgia. The southern ties are most likely related to the Great Migration of African Americans to northern industrial cities.

More from NYTimes:

This map shows an index of connectedness, created using friendship links between pairs of anonymous Facebook users from a snapshot of the platform in April 2016. The researchers aggregated the links at the county level, so neither the Times nor other academics working with the data can identify individual users within it, or how many Facebook users live in each county. Because counties with more people invariably have links to more places, this map rescales the index to account for differences in population.

Workshop: Data, Mapping, and Research Justice

I’ll be teaching my workshop on data and mapping again this October 2018 with Co.Open/Allied Media Projects.

During the 4-week course we will journey through the entire mapping process; from paper survey to digital database, basic map visualizations, and finally analysis. We will be working with free and open source software (QGIS, LibreOffice, Inkscape, etc.).

Check out some of the past course projects:

Esther Loopstra created this beautiful hand drawn illustration map after visiting Detroit for a conference. She excellently highlights: Detroit Vegan Soul, Russel Street Deli, Dilla’s Delights, Mudgie’s Deli, Seva Detroit, Cass Cafe, Ima, Pie Sci, and Trinosophes.

 

Map: Detroit Strategic Plan for Transportation 2.0

Screen Shot 2018-09-09 at 11.03.57 AM.png

This map comes from the new “Detroit Strategic Plan for Transportation” representing DDOT 2.0, a high-frequency transit system that serves 60% of Detroiters.

Check out the full plan HERE

Possibly the most exciting elements of the plan are for reductions in parking and removal of requirements for parking at new developments when located near transit.

Map: Racial Steering in Detroit Housing 2003-2005

Screen Shot 2018-08-27 at 9.10.48 AM

In 2007, the National Fair Housing Alliance (NFHA) filed a lawsuit against Century 21 Real Estate LLC and it’s franchisee, Centry 21 Town and Country, in federal court. During the 2003-2005 period, NFHA tested 14 real estate agents of which 9 engaged in “racial steering” encouraging whites to seek homes in predominantly white neighborhoods such as the Grosse Pointes and blacks to seek homes in predominantly black neighborhoods such as East English Village.

Map: Detroit Streets and Real Estate 1872

silas-farmer-1872

This street map of Detroit was created by city surveyor, Eugene Robinson and published by the Silas Farmer Company (31 Monroe Ave, corner of Farmer St.)

An additional ink stamp on the map reads:

“Waterman’s Real Estate Exchange. First-class Private Residences, Vacant Lots on the Best Streets. Business Property for sale by WM. J. WATERMAN, opposite the Post Office.”

Maps have been such an impactful tool for real estate and land developers for over a century.

Map: Hastings-Oakland Expressway in Detroit

Oakland-Hastings-Expressway

This map of the proposed location of what we now know as Interstate 75 comes from the Detroit Public Library Digital Collections. I had heard plenty about the expressway razing Paradise Valley and the center of Detroit’s black community along Hastings Street, but never heard the expressway referred to as Hastings-Oakland.

Map of Hastings-Oakland Expressway in Detroit; proposed general location plan Jefferson Ave. to Alexandrine. Label on mount: “Hastings-Oakland Expressway, River to Mack.” Printed on mount: “Produced by Florez Incorporated, Detroit, Mich.”

Map: Polar Histogram of Detroit Roadways

Screen Shot 2018-07-19 at 11.24.41 PM

Mapbox engineer, Vladimir Agafonkin, decided to make the polar histogram of roadways interactive with this map inspired by the work of Seth Kadish and Geoff Boeing. Incredible method to summarize the development patterns of cities.

Map: Downtown Detroit Civic Center 1878

civic-center-1878

File this under the “unbuilt Detroit” category, (traced by H.F.J.) from E. H. Bennet architects in Chicago. North of Campus Martius, this “civic center,” located at what is now Grand Circus Park, would have functioned as a true Downtown hub for government, entertainment, and city life.

Map: The Native Land of Detroit

Screen Shot 2018-07-19 at 11.18.49 PM

Just a reminder that the land you may or may not own or occupy in Detroit was never anyone’s to take, divide, or sell. We are all on native land. In Detroit, that means the land of:

  • Anishinabe
  • Haudenosauneega
  • Miami
  • Odawa
  • Peoria
  • Potawatomi

Map: Detroit Eastern Market’s Regional Foodshed

EMC-foodshed

Detroit’s Eastern Market is known as a regional food hub, where producers and consumers meet to connect the food system supply chain. I was curious as to the extent of Eastern Market’s ability to aggregate and distribute fresh produce in the region and decided to map growers and farmers from the list of weekly Saturday market vendors.

While Eastern Market’s reach is statewide even into Ohio and Ontario, the vast majority of food hub participants are within 40 miles of the market. There are a very small number of growers from within the City of Detroit and the majority come from Macomb and St. Clair counties to the Northeast. These areas within the 40 mile range are, not surprisingly, at the edge of the urban – rural transition.

Map: Detroit and Grosse Pointe in 1904

Screen Shot 2018-07-18 at 8.35.08 AM

This map is from the “Detailed official atlas of Wayne County, Michigan” from 1904 “compiled and drawn from Authentic records and private surveys by W.C. Sauer, C.E.

If you happened to live East of Conner Street in 1904, you were a Grosse Pointer.

Map: Detroit Rental Property Compliance 2018

Screen Shot 2018-02-28 at 10.31.14 AM

In 2018, the City of Detroit launched a massive effort to determine a baseline for all rental properties and their levels of compliance within the city. This year will cover 5 zip codes, with others (total of 31 zip codes) being assessed in following years up until 2020.

“City of Detroit building inspectors will begin their efforts on Feb. 1 to identify every rental property in Detroit and have them registered in compliance with city codes. The goal of the new ordinance is to ensure that every renter in Detroit is living in a property that is safe and up to code by the middle of 2020.”
