Concentrations of Young Adults in Dayton & Vicinity

The young adult age cohort is the one that seems to be leaving Dayton (see the Producing People for Export post), but there still are a lot here. This is an interesting age group, flexible early career people. As singles these are most likely to support lively arts/music/nightlife scene. But also young adults are the ones starting up families, so in the market for houses, daycare, schools, and consumer goods.

The census has a 100 percent count for basic demographic information like race, sex, and age, so one can build some stats to show how many people 21 and up are in a census tract, and also how many are in the 21-34 category (the one I use for young adults), both as % and as total county.

Graphing these out by census tract, highest to lowest % of young adult 21-34, one sees top tracts are for Wright-Patterson (military living on-base) and University of Dayton (the UD “student ghetto” plus Fairgrounds neighborhood), followed by some secondary clusters, a mid range, and then a drop-off

Mapping the top tracts, one sees the top four percentage tracts out in the suburbs, some inner ring tracts (Kettering east of Oakwood and but two tracts in the city comprising Shroyer Park, Walnut Hills ,and Ohmer Park. But there seems to be a pretty strong concentration in East Dayton for lower percentages, too. East Dayton seems to have quite a density of the 21-34 cohort

Looking at absolute numbers, the top tracts aside from UD and the base are clustered in the south suburbs, south of I-675, on either side of I-75.



What it Looks Like

Taking a look at the top suburban tracts, what they look like from the air, and on the ground. Lots of apartment/condo clusters in these tracts, and in 501.03 some brand new starter home plats.

501.03 bears some further study as it has some early –mid 1970s multifamily, an era where the “woodsy shedsy” ski lodge style was popular. Also perhaps early examples of Planned Unit Development.



Multifamily with Corporate presence in the background. If one worked at Lexis-Nexis or Newmark one could walk or bike to work.
Tract 218 has a concentration of subsidized housing but also some nicer modern apartments.



This tract is up on the hills climbing out of the Miami Valley, so one glimpses some nice views on occasion. It’s mostly 1970s multi-famliy, with some single family out along “King Richard”. Part of West Carollton.

Except for this complex.

“Centerville Park” (pretty far from Centerville, actually) was the first apartment complex along OH 725. Bilt in the mid 1960s, it pre-dated the Dayton Mall, and most of the suburban development between Miamisburg and Centerville. Maybe a historic designation is in order? It's 40 years old or older.


Probably 1970s housing. There's actually a lot of convenience shopping close buy. Theoretically walkable, but I'll bet no one does (note the walkway or bikeway running in front of the units, left to right)
This tract is the old Village of Riverside, Overlook, and some other stuff. The concentration here in at the huge apartment complex in the heart of Riverside, built to replace WWII temporary housing.

We'll take a closer look at the Dayton high % /high # tracts later, particularly Woodland Hills and Shroyer Park.

But it seems for suburbia, for 20 and 30-something neighborhoods, one is looking at suburban apartments and condos, and maybe some starter-home plats. I didnt show Tract 301, which is also a top concentration, but it is not much different from whats shown above, except two trailer parks appear as concentrations for 21-34, as well as apartment complexes.

On The Reading List

"[A]n original and complex explanation for the urban crisis that transformed Oakland, California, from 1945 to 1978. . . . By placing the history of Oakland and its African American community in a new theoretical framework that emphasizes suburban growth, tax revolts, and battles over land, jobs, and political power, Self has challenged historians to reconsider the way that they study postwar black urban communities."--Albert S. Broussard, Journal of American History

American Babylon traces the dialectic of suburbanization and black power in my hometown of Oakland, California. Encapsulating the postwar history of hundreds of mid-sized American cities, Robert Self's original and fascinating case study historicizes city-suburb racial segregation as a creation within living memory. We cannot heal or make sense of the nation we live in now without American Babylon."--Nell Irvin Painter, Princeton University, author of Southern History across the Color Line



I am going to follow through on those black history threads I posted earlier in the month and continue the story into the 1930s, 40s, and into modern times. The "road to Chocolate City" (tho Dayton is really Two-Tone Town). American Babylon looks like a good backgrounder and example from another small-to-midsize city

Racial Disparities by Occupation Class: Montgomery County

The exploration of racial disparities in production work leads causes one to question whether similar disparities exist across other occupations.

Again, working with the custom table feature and Census 2000 SF 4 at American Factfinder, one can generated data by occupation classification for whites and blacks across the county.

Here is a comparison. One can see that blacks lead in certain occupational groupings, particularly services (but also in production and transportation and material handling), and whites in managerial, professional and technical work (but this group does have a substantial black presence).


Within the professional & managerial group blacks have more of a concentration in community and social services and education, while whites are more in top level corporate jobs and things like engineering.

The really interesting differentials are in services.

This is the category where blacks are the most. But where are they? Services has four subcategories:

  • Personal Services
  • Building and Grounds Maintenance
  • Protective Services
  • Food Preperation & Services
  • Health Care Support Workers
Comparing blacks and whites it seems blacks are distributed proportionally across most of this category, but with a slight concentration in health care.


Whites, however have a very high concentration, nearly a third, in Food Service: waiters, waitresses, food prep, chefs, short order cooks, etc.

This was sort of unexpected, so let’s take a closer look at white food service workers. Graphing tracts with white food service workers, the UD area just dominates, probably due to college kids waiting tables for their tuition, so that tract is a special case.

Beyond that one can see some breaks and clusters

Which map out so:
The even spread out into suburbia , including the top tracts seems to indicate that this is probably a situation of teenagers and college kids working in fast food or other food services, since this sample is based on “working adults 16 years or over”.

Interesting to see one of the top tracts mapping out near UD: perhaps the “student ghetto”, the true off-campus student ghetto, not the “UD Houses” off Brown Street, but the area east of UD. It would be interesting to map out young adults to see if there is a geographic correlation, to see if there is indeed a second student ghetto back behind Woodland Cemetery.

We’ll take a closer look at young adults next, which will be considerable more accurate as the census does basic demographics as a 100% count, not a sample.

"This Is Dayton": Creative Region Community Pride Initiative

More information on the Creative Region Initiatives from last month. From the Dayton Most Metro website, some more information on the “Community Pride” initiative...an excerpt from a post at Dayton Most Metro:

Dayton has a huge inferiority complex …We realize that if we don't address this issue, we're behind the proverbial 8 ball.

So our vision is to reflect positive images and facts about our region back to the community so that we have tangible reasons to be very proud of Dayton (and that means the Dayton REGION, not just downtown). We are creating posters with facts & tidbits under the heading of "This is Dayton". We plan to develop a style sheet that can ultimately be used by other communities or even organizations so there is a consistent, unified look.

These posters can then be put up in vacant store fronts throughout the region, on billboards, inside and on the back of busses, at the airport, etc. These points of pride can help Daytonians see tangible reasons to feel good about our home, and show visitors our sense of community pride.

The post goes on with a call for volunteers to participate in the program, particularly people with a graphic design and marketing background to help with the layout, style sheet, production things, etc.

I am reminded a bit of that supergraphics campaign they have in Louisville with pictures of famous (ex)Louisvillians around downtown. This is both less and more than that, though.

“This Is Dayton” could be something equally simple, and a way to engage people. One does this by showing pix of people at work or doing things, with some factoid in smaller type, and a large-type “This Is Dayton” slogan

Here are a few quick takes on the concept, taking in the idea of the Dayton “region” as subject These are more like a “travel poster”, minimalist, as my taste in graphics runs more to HfG Ulm and the Swiss Style.














(I wasn’t feeling too inspired with these, so be kind)

I can see this as a positive step to fight against the endemic negativity and, at best, apathy in this area (which, to be brutally frank, gets old really fast). Though the above excerpt mentions pitching this to visitors the hard sell is going to be the locals, who are usually more negative and unappreciative than outsiders.

In any case, They are looking for volunteers, so if anyone reading this with a graphic design and/or advertising background wants to contribute, follow this link, which will take you to a discussion thread and an e-mail contact for volunteering in real-time.

Racial Disparities in the Dayton Manufacturing Sector

Black factory workers: hurt worst by the decline in manufacturing in the Dayton area?.

Conventional wisdom is that the assembly and fabrication (and textiles/clothing) category of manufacturing is most under threat for relocation to low wage labor markets. If this happens it will disproportionably impact the local Black community, leading to increased unemployment and downward mobility.

Census SF 4, which is based on a 2000 census sample, aggregates production workers into eight job classes (based on BLS Standard Occupational Classification System, production occupatons available in detail here). The census also permits the separation of these employment classifications by race, so one can if there are any discrepancies.

And there are.

Graphing out white and black by job classification for production work, the big differences are in the Assembly & Fabrication and Metalworking & Plastics categories. Blacks working in production work are 40% in Assembly and Fabrication, the largest category for blacks compared to 20.9for whites. The base category for whites is metalworking, but this is third for blacks.


Both races are about even in the “Other “category, which is a grab-bag of production jobs. Unfortunately the census doesn’t permit further granularity for this category.

For the smaller categories, Blacks have a higher % in Textiles & Clothing and Whites are more in Printing.


So, as one can see blacks working in manufacturing could really be at threat of unemployment if Assembly & Fabrication work is going away, since such a high % of them working in production work fall into this category.

The Geography of Blacks in Assembly & Fabrication Work:


Graphing out the census tracts, highest number of A&F workers to lowest, to see if there are any breaks and clusters



And then mapping out the workforce based on the breaks suggested by the bar graph, again using 2000 data. One can see some interesting geographic clusters, in Trotwood and the Gettysburg Corridor, along Salem and Main, and the start of some concentrations in Huber, out into Englewood, and perhaps in Miami Twp.

What’s sad about this is that one can see outward mobility of black blue collar workers to better conditions in the suburbs or newer city neighborhoods, which begs the question of what are the impacts of job losses since 2000 on this upward and outward mobility, and on neighborhoods with a lot of A & F workers? (note this just looks at assembly workers).

Today's Geography of Manufacturing

With all the interest in defense work and IT and the Creative Class Dayton still is a factory town. As of 2005 manufacturing ranked second in employment, providing 18% of the of private sector jobs in Montgomery County (ranking number two, just behind health care sector), and ranking number one in pumping money into the local economy, providing 20% of the aggregated private sector payroll in the county.

We’ve looked at some historical aspects of “The City of 1,000 Factories” (in 2005 there were 838 manufacturing establishments), so let’s look at today’s geography of manufacturing: where the plants are and where the workers live.

Sources for this post will be Zip Business Patterns (from the CenStats website) for the location of manufacturing establishment and Census 2000 SF4 @ American Factfinder for concentrations of production workers

Based on 2000 data the following map shows the census tracts with high concentrations of production workers as a % of the employed population, as well as areas with a low % of workers. Presumably the areas with a high concentration would be feeling a pinch if factory work is disappearing from the region.


"Production Worker” as defined by the Census (using BLS categories, and showing the % for Montgomery County)are these types of workers:

  • Other (including supervisors & foremen: 34%
  • Metal & plastics workers: 29%
  • Assemblers & fabricators: 25%
  • Textile, apparel, & furnishings workers: 4%
  • Printing workers: 3%
  • Food processing workers: 3%
  • Plant & system operators: 1%
  • Woodworkers: 1%
(the dreaded "other" category ranks #1)

Zip business patterns does not provide detail on the number of employees per sector (probably for confidentiality purposes), but does tell how many manufacturing establishments are in a zip code and the size range (e.g. 1-5 employees, 500-999 employees, etc). So one can roughly locate the larger establishments (employing over 100 workers) as well as concentrations of establishments.

Using the 2000 numbers this was the geography of manufacturing establishments 8 years ago.

2005 is the most recent year for the CenStats data source, and concentrations haven’t changed much since 2000:
…the top concentrations hold about 42% of all manufacturing establishments in Montgomery County, so this is a fairly geographically concentrated economic sector.

However there has been a decrease in net number of establishments, as well as downsizing or closure of some of the larger ones.




East Dayton was the big loser, but other zip codes lost as well, including Vandalia and the area along I -75 north of the city.

Countywide there has been an increase in smaller establishments, but a decrease in the number of mid-range companies. Interestingly between 2000 and 2005 the 1000 plus size range has not changed in net number of establishments.





One can see how manufacturing has suburbanized over the years, but still with substantial concentrations within Dayton, particularly in Old North Dayton and the east side north of US 35 .

The post looked at the de-industrialization of the west side. Interestingly this area hasn’t deindustrialized that much in the 2000-2005 range as the zips comprising this area actually had a net drop of one establishment, moving from 21 to 20 establishments.

The last mass-employment 1000-employees-&-up establishments did leave or downsize, dropping from 2 in 2000 to none in 2005, showing the closure of the Delphi Wisconsin Boulevard plant and downsizing at Inland.

The Deindustrialization of West Dayton

The Origins of the Urban Crisis continues to inspire analyses of Dayton as a comparison. I think a key chapter in Sugrues books is Chapter 5, “The Damning Mark of False Prosperities: The Deindustrialization of Detroit" ( pages 125 through 177 of the first edition), which provides the economic context for the declining fortunes of the Detroits black community.

This chapter talks about automation and shifting business practices wiping out entire categories of jobs in the auto plants, and driving out independent suppliers and producers, changes which hit inner city Detroit particularly hard, and resulted in an increase in long-term unemployment, leading to widespread urban poverty, which also impacted neighborhood retail.

Dayton was a center for the auto sector, but was apparently much more economically diversified than Detroit, as we’ve seen by the previous discussion of unionization, which was directed at a variety of industry; from foundries to electrical equipment makers to machine builders and so forth.

Though I discussed Dayton's deindustrialization in a general sense in an earlier post I want to focus here on the west side.

As one can see by this map the west side was quite the manufacturing center, with plants mostly strung out along the rail lines radiating from the Great Miami railroad bridge.

The larger plants were associated with the auto industry: Delco, Inland, Dayton Tire. But also the large McCalls printing plant and a collection of mid-sized manufacturing establishments





Dayton industrial employment, starting in 1947, using census sources. The city was already was seeing a decline in factory work in the 1950s, which is consistent with Sugrue’s findings for inner city Detroit. Yet this was temporary, and manufacturing employment surged again in the 1960s.
The big drop happens after 1970, where there is a drastic slide into the 1980s, and then another drop into the 1990s. Though the stats don’t narrow it down to the west side, one can assume most of the manufacturing left in this era, which would correlate with an increase in long term unemployment and urban poverty. Presumably one could consult the city directories and find out when a plant closed (though employment decline could precede closure).

The fate of the labeled plants will be illustrated downthread.


By 2008 the west side was de-industrialized. Nearly all of the large manufacturing establishments are gone, and most of the mid-size ones as well. The last large auto industry plant, Inland, is threatened with closure.

Accompanying deindustrialization was the expansion of poverty across the west side. There were poor areas here in 1970 and before, but poverty expanded and deepened along with the loss of industry. One wonders if it would be possible to draw the same corellation that Sugrue did in Detroit about the connection between growth in poverty and loss of factory work?

By 2006, the west side is also experiencing large scale housing vacancy and abandonment: first the factorys go, then the people, then the houses and shops.

Though manufacturing has left there are not too many empty structures. Extensive square feet of abandoned factory like these are actually pretty rare (there was a 6 or 7 story loft building in the grassy area to the right of the Sunshine Biscuit plant):


Most of the really big plants are gone. Example is the old Moraine Products plant, which started as a munitions factory in WWI (closed in the 1990s)(Sanborn at top shows extent of the plant in 1950)


Kuhns (later Nibco) Foundry: from an extensive complex to a rubble strewn field (closed in the 1980s, I think)
Factories usually turn into vacant lots (McCall Printing, partially torn down in the 1990s or early 2000s)

….or in this case, a factory turned into a prairie (Dayton Tire closed in 1981).


The site of a big factory employing hundreds, perhaps over a thousand? Like it was never there.

Today there are few factories on the west side. A rare example is this plant on Mound Street. Interestingly, this is set in a former residential area cleared out by abandonment and urban renewal, not in an old industrial district:


Smokestack amidst a ruin field as headstone for the west side industrial graveyard.


...reminds me a bit of Si Kahns' Aragon Mill.


1. At the east end of town, at the foot of the hill
Stands a chimney so tall that says "Aragon Mill."
But there's no smoke at all coming out of the stack.
The mill has shut down and it ain't a-coming back.

2. Well, I'm too old to work, and I'm too young to die.
Tell me, where shall we go, My old gal and I?
There's no children at all in the narrow empty street.
The mill has closed down; it's so quiet I can't sleep.

3. Yes, the mill has shut down; it's the only life I know
Tell me, where will I go, Tell me, where will I go?
And the only tune I hear, is the sound of the wind
As it blows through the town,
Weave and spin, weave and spin.
