Local in Ann Arbor

Ann Arbor is rushing toward the future.  Each day, each moment, events small and large are shaping the new reality.  There is no possibility of remaining anchored in the past because we are leaving that behind us.  The only question is what shape the future will take and who will frame it.  What will emergent Ann Arbor be like and whose vision will best describe it?

Much of Ann Arbor’s political polarization in recent years has been from our various efforts to seize the future.  One problem with visualizing the future is that none of us has a perfect understanding of the outcome from a specific action.  We can surmise, we can expect, we can predict.  Often, whether we understand this or not, we are following a model (a set of hypothetical outcomes based on a perceived mechanism).  But while a model can be used to forecast, it is likely to fail at some level because other factors have not been considered.

My best example of this is the Washtenaw County budget director’s model for revenue in the 2002-2004 timeframe.  “The best predictor of the future is the past.”  Since development (sprawl) was very rapid, the tax revenue for the County was increasing by 6% a year or more.  He drew a straight-line curve showing a huge growth in funds over ten years.  So the County forged ahead with several high-ticket projects in confidence that the funds would be available to pay the costs.  He failed to anticipate either the many policy brakes (Greenbelt, etc.) governments put on sprawl or the massive economic collapse that began in Michigan as early as 2006.

Currently, much policy in Ann Arbor is being driven by models, voiced or implied. For example, the model that if we continue to increase the housing supply, even with extremely high-priced luxury housing, the supply-demand ratio will mean that other housing in the area will become more affordable.  This is stated as an immovable law of nature.

But that can only be tested by putting a particular policy into place.  The outcome will be fixed, whether it fulfills that prediction or not. So, often discussion of the emergent Ann Arbor is composed of warring models and thought experiments.  A piece is missing, though.

Have we as a populace and as a civic body really examined the critical questions of what that emergent Ann Arbor should be?

We have not really elucidated our game board.  How can we test proposed actions and initiatives against a desired outcome if we don’t even have a picture of the outcome?  Do we really know what we want or what the future we are trying to achieve looks like? This leaves so many questions unanswered.  We’ll try to consider them one at a time.

1.Where and what is Ann Arbor?

Ann Arbor Zip Codes and Addresses

To some extent, Ann Arbor is what you make of it, geographically, at least.  There is, of course, the City of Ann Arbor, a landlocked city that is now annexing its final few township islands.  Some of those islands are still part of Ann Arbor Township, a completely different municipality.  But there are many people who have Ann Arbor addresses who don’t live within the city limits. Note that Ann Arbor zip codes include addresses in Superior, Webster, Scio, Lodi and Pittsfield Townships. (Only Ypsilanti does not share an Ann Arbor zip code.)

This is significant because though all those addresses pay property tax to their local governments, many people and businesses in them identify themselves as “Ann Arbor” and have an interest in the future of that label.

The Ann Arbor Public Schools

AAPS School District. The eastern border in Ypsilanti is Golfside Avenue.

Another “Ann Arbor” is the Ann Arbor Public School District.  The AAPS is thought to provide high-quality schools and it is an important feature of the Ann Arbor image and reality.  It is a major real estate selling point. (Often, houses and condominiums for sale in the townships are labeled, “Ann Arbor schools”.)

Of course, children who attend these schools have a common background because of that and it creates a sense of community. (Parents are engaged too.) Further, everyone in the district votes for the AAPS School Board and pays AAPS school taxes.

These boundaries are identical for the Ann Arbor District Library.  The library was historically part of the school district.  The AADL split from the AAPS in 1996 and succeeded in persuading residents to vote in a perpetual millage (does not have to be renewed) of 2.0 mills.  The AADL has won many awards and has multiple activities and several branches, including one in Pittsfield Township. It is an important community center.

Ann Arbor Metropolitan Statistical Area

Portion of SE Michigan as shown in U.S. Census map of MSAs for the U.S.A. Note that Washtenaw County is “Ann Arbor”. The adjacent MSA, Detroit-Warren-Dearborn, defines the combined Detroit Metro.

As we noted in an earlier post about regions including Ann Arbor,  it was determined some years ago that the magic of the name, “Ann Arbor” could be used as a business and economic development asset for the entire county.   Thus, Ann Arbor SPARK became “Ann Arbor, USA” and a marketing effort defined the entire county region as Ann Arbor.  This designation has been solidified by the U.S. Census descriptor of our primary Census area (the Metropolitan Statistical Area, or MSA) as “Ann Arbor” – but its boundaries are those of Washtenaw County.

The actual Census was in 2010. It is supposed to be a comprehensive picture of the American population and includes much demographic and economic information.  The basic Census uses a combination of paper forms and door-to-door interviews.  The American Community Survey (ACS) continues to  do spot surveys and produces updated information on many fronts, especially demographic and economic data.  (Because it is not comprehensive, one needs to be cautious about drawing conclusions, since sampling error is always a possibility.)  Graphic displays of this information can show a map of the U.S. in which various factors are called out by MSA.  With just a little practice, one can quickly pick out Washtenaw County, right next to Wayne County in the far southeastern corner.

This has led to much confusion because so many articles, especially those covering some national topic, use the Census MSA data for analysis.  Data miners and analysts pick up all that nice easily accessible data and draw conclusions which show up in headlines that say “Ann Arbor is…”   A good example was Richard Florida’s 2015 article on  America’s Most Economically Segregated Cities. Headlines indicated that Ann Arbor was the 8th most economically segregated.  Florida’s article was based on a longer study he did earlier, which in turn was based on a Pew Research Center study.  The source of data for all?  You guessed it – the Census.  But while Florida referred often to “metros”, the title of his study was Segregated City.  You’d have to forgive the casual reader for supposing that it meant Ann Arbor City. But if you examine the map closely, you’ll see that little Washtenaw County rectangle.  Since this article was picked up by a number of mainstream media, the conflation and confusion was magnified.

Ann Arbor resident Jean Henry reminded The Ann that despite A2’s recent accolades, we were ranked eighth in income segregation by The New York Times.  (Quoted in The Ann, Ranking the Rankers)

Washtenaw County median income by census tract. Dark green is highest income.

This is more than confusing, it conveys the wrong information.  Washtenaw County is indeed an example of income segregation.  But Ann Arbor City actually contains a large number of the lower-income census tracts.  The county includes some very well-heeled communities outside of Ann Arbor and Ypsilanti, such as Barton Village and several of the townships.  It is necessary to go down to the level of individual census tracts to see that, and few studies do that.

How do we rate?

By now it has gotten so commonplace to see “Ann Arbor number one” stories that we could almost assume that we have somehow done everything perfectly.  How can you argue with success?  But that doesn’t necessarily jibe with the daily experience of many, or keep us from arguing about details.  Ann Arbor author Patti S. Smith, writing in The Ann, analyzed a variety of the surveys and rating stories and made some good observations in her article, Ranking the Rankers: Just What do Those Top Ten Lists Mean? She offered a number of cautions, including that one should examine the methodology used by the ratings’ source.

One of the recent ratings came from Niche.com – this one was pretty good.  Ann Arbor is the best city in the U.S. to live in!  Looking a little closer, it seems really good since we only scored Bs on housing, crime, jobs, and cost of living, and C on weather.  They partly base their ranking on surveys and reviews.  But also on many publicly available data bases.  Yup, the Census Bureau was the first on the list.

Where are we talking about?

The take-home message?  It is clear that Ann Arbor is both a city and a region.  In another state it would probably be a larger city, perhaps with about the same geographic area as those zip codes, or even larger.  We function much like a metropolitan area.  But we don’t really have a command of that entire area, yet we are expected to serve it in many ways.

It is important as we form an idea of where our future should lead us that we have a clear understanding of the Where that we mean.  Sometimes real “granularity” is needed (getting down to the details, perhaps as small as specific neighborhoods or even just a few blocks). Sometimes it is about the greater metropolitan region or sometimes as broad as the County. Often when we are talking about the urban area, the City of Ypsilanti becomes important to our discussion because we have so many dependencies on one another.  But policy discussions about future initiatives should be informed by an acute awareness of which Ann Arbor we are assigning characteristics or responsibility to. Too often, our leaders make sweeping statements about what Ann Arbor is or should be.  For those of us especially who live in the City of Ann Arbor, we need to know where they are.
