Pictorial Map of the 18th Annual Convention of the National Association of Real Estate Boards City of Detroit 1925

In 1925, the National Association of Real Estate Boards declared: “Detroit is yours! Realtors!”

On this map, the pictorial map people are saying a myriad of gems about the city and I wish I could transcribe them all:

“This looks as peppy as Los Angeles.”

“Well well I thought Old Canada was North of the U.S.”

“Look at that Jim! Why it’s bigger than our broom factory!” [looking at Ford Motors in Highland Park]

One interesting note added to many green “undeveloped” areas labeled as “Subdividing active here” since much of the city beyond Grand Boulevard was still vacant.

Map: GLWA Stormwater Control in Metro Detroit

The University of Michigan Urban Collaboratory worked with the Great Lakes Water Authority (GLWA) in 2018 to better handle combined sewer overflows in real-time. More from the project:

… they found that Combined Sewer Overflows have been occurring when additional sewer capacity is available. Rather than increasing the amount of storage with costly infrastructure improvements, the research team was able to demonstrate their ability to use a real-time control approach to significantly improve the existing GLWA wastewater and CSO management system by reducing both the occurrence of CSOs and peak flows going to the treatment facility.

Map: Belle Isle Commons

Gehl worked with the Belle Isle Conservancy to reimagine what the area around the major cultural institutions on the island. More from Gehl:

Belle Isle is Detroit’s premier large open space and home to some of the city’s iconic cultural institutions. Today, however, the public space around the core destinations of the Isle invites for car-first, one-off visits — rather than a continuous, lingering experience. Gehl was engaged by the Belle Isle Conservancy to reimagine this key area of the isle as the Belle Isle Commons: a cohesive, welcoming public space that connects cultural destinations, and a destination for Detroiters and visitors in its own right.

Map: The Original Midtown Community 1953

This historic gem of a map comes from the Reuther Library and Archives, “Community Councils Manual, Dec. 1953” (page 5) published by the Detroit Federation of Community Councils. I’ve been diving into neighborhood histories and came across mentions of a “Midtown Community Council” in the 1950s and had to dig in further.

The Detroit Federation of Community Councils was an association of 14 community councils in Detroit. United Community Services, which was a precursor to the United Way, sponsored the Federation and its member Councils, and supplied them with professional staff to assist.

The Midtown Community Council was one of those broad neighborhood associations that served an area now represented by the West Grand Boulevard Collaborative. A focus of the Midtown Community Council was activity on 12th Street, promoting positive race relations with new Black residents, and preserving some the Jewish heritage of the area. Council meetings were held at the Grace Episcopal Church, the Duffield Library Branch, and the Jewish Community Council.

A newspaper clipping from the National Jewish Post in 1947 noted that the Jewish Community Council began a study of potential legal action, “to stop the efforts of real estate dealers seeking to capitalize on panic sales among Jewish property owners in the Detroit 12th street district because of an influx of negros.” The Jewish Community Council leadership noted that mass evacuation would harm both Jewish and Black families. The real estate dealers were found to be non-Jewish and were not members of the community.

It’s interesting to find these bits of history where blockbusting tactics associated with real estate redlining were actively harming communities and they were actively trying to find alternatives. This is an important point in the history of 12th street as we think about the long process of racial discrimination that led to the 1967 civil disturbance.

Map: Detroit Food Pantry Finder 2025

The City of Detroit has taken small steps to better engage with the food system in moments of crisis. The first was food box distribution during COVID-19 and now they have a team verifying food pantries in the midst of uncertainty with federal nutrition benefits. This kind of verification is critical to make sure people can find the right resources and I truly hope this is connected to the wider safety net efforts of the United Way’s community information exchange.

Children living in poverty. This is a reversal from past improvement. Overall Detroit has a poverty rate around 34%, but it is much higher for children. In the recent State of Michigan budget $270 million was allocated for the RxKids program that has seen success in Flint. The State funding could allow the program to expand into Wayne County and specifically Detroit. (Local 4)

Units of unsubsidized market-rate housing constructed so far in 2025. Many apartment buildings are going into foreclosure. Property insurance has doubled in the last few years. Interest rates are up, making loans or refinancing more expensive. Construction and maintenance costs are still sky-high. And Detroit has some of the highest property tax rates in the country. There are strong concerns that rent prices will increase to cover costs. (Outlier Media).

100%

The pay gap between commuters and Detroiters with jobs is double (average commuter wage is $100,000 vs. Detroiter wage is $53,000). The recent City of Detroit University Economic Analysis Partnership highlighted this disparity. Commuters hold almost 75% of all jobs in Detroit. Tracked from 2010 to 2020, the gap has only gotten worse. (Axios)

48,823

DPSCD student enrollment is up! This same time in 2024: 48,386 and 2023: 47,401.
“As of Day 11, we are trending 437 students more than last year and 1,422 more students as compared to two years ago,” Vitti said.
Total enrollment: 52,505 K-12 students are enrolled in DPSCD compared to 2024: 53,044 students. (BridgeDetroit)

This is really important, but we don’t think about it as much as we should. Detroit is bordered by 20 other local municipalities including two fully surrounded by the city, and one international city (making it 21?) – Windsor (239 municipalities in 7-county region). Shoutout to the Greater Detroit Windsor Project Conference set to happen at the WSU Law School on October 17th to explore connections and opportunities in our region!

Map: Detroit Walkable Accessibility Score

The City of Detroit has a clear walkability problem outside of certain zones, like Midtown, Corktown, Hamtramck, or pockets in Northwest Detroit.

More from the project:

… the Walkable Accessibility Score measures the average accessibility to nearby urban amenities from neighbourhood centers. To create the WAS, we first calculate the distance from every block group centroid (shown on the map above) to the nearest 30 grocery stores, pharmacies, retail shops, banks, bookstores, schools, parks, hotels, restaurants, cafes, and bakeries. Then, the distance to each of these amenities is weighted by how far away it is from the block group centroid, up to a maximum distance of around 1600m. A block group with 30 amenities all located within a very short distance of its center (e.g., 400m) recieves a full value of ’30’ for the WAS. Using POI data, we are able to calculate the WAS for every block group in the continental US for every year from 1997-2019. For more detail, see the full paper here.

Detroit Recreation Property Map 1976

I can’t remember where I found this map, but I’m glad that I did. The map is huge and could only be scanned using the large format, flat-bed scanner at the Reuther Library. This map is printed on this heavy paper, thick to the touch almost like a stiff fabric.

The map has some weathering and discoloration, but was clearly a map in active use from at least 1972 to 1976. What I love most about it is the active crossing out of property locations, like the “Seward 12th Playlot” and the active “Additions & Changes” including name changes, like “Seward-12th Playlot.” The map total the acres for the recreation Department at 5850 as of 1/72 (January 1972) and 5860 as of 1/76 (January 1976). There is a mystery highlighted circle at Mt. Elliott north of Gratiot. What was the Recreation Department planning in 1976?

This map is part of the Hill Map Collection digitized in partnership with the Reuther Library and Archives as part of the Detroit Atlas Collaboration funded in part by the WSU Union of Part Time Faculty (UPTF) Professional Development Fund.

Map: Distressed Communities Index in Detroit 2025

I don’t generally look to these index rankings of Detroit, but the comparisons are powerful. Detroit is a donut hole in the region; surrounded by communities of higher prosperity and higher opportunity. The city sits on par with Cleveland, Buffalo, Newark, and Memphis.

What are the known strategies and policies that build opportunity in distressed communities?
