The Detroit Evolution Animation

Created in gratitude to the University of Michigan’s PhD program in architecture
Related: The New York City Evolution Animation

.

Soundtrack: “Pruitt Igoe” from Koyaanisqatsi, directed by Godfrey Reggio and composed by Philip Glass.

.

This film traces Detroit’s evolution from its origins as a French trading post in the 1700s, to its explosion as a metropolis, followed by its precipitous decline as a symbol of America’s post-industrial urban landscape. The film weaves in details about the city’s politics, population, and technology – all of which influenced the city’s geography and built environment. At each phase in urban history, the built environment grew and was modified in direct response to political events like racial segregation, population changes like the Great Migration, technology developments like the mass-produced car, and government interventions like urban renewal.
The animation tells the story of Detroit specifically and the story of American cities more broadly. To varying degrees, the path of Detroit’s development mirrors hundreds of other smaller cities and towns scattered across the American Northeast and Midwest. No other American city witnessed as large a population loss, as dramatic 1960s racial unrest, or as radical a transformation from symbol of progress into symbol of decay. To a lesser degree, other places in America followed Detroit in lockstep. Urban renewal projects, highway construction, racial tensions, suburban growth, and infrastructure under-investment happened across America, and in parallel to Detroit.
However, the most dramatic transformation of Detroit is left unwritten in this film. Beneath the surface-level events of political conflict and urban change, the largest event in Detroit is not unique to Detroit. As filmmaker Godfrey Reggio describes, the most important theme in the history of civilization is “the transiting from all nature, or the natural environment as our hosts of life for human habitation, into a technological milieu into mass technology as the environment of life.” European cities developed slowly and gradually over centuries, in the process removing all memory of the natural landscape before civilization. American cities are unique in their youth and speed of growth. They are new enough that an active memory survives through place names and written records of the landscape and indigenous peoples who lived there before colonization. As the oldest colonial settlement west of the Appalachians, and as the city that perfected the mass-produced automobile, Detroit becomes the prime symbol of man’s transformation of his home from a natural world into a technological society removed from nature.

The accompanying music is by composer Philip Glass and was written for Godfrey Reggio’s 1982 experimental documentary Koyaanisqatsi. The shifting layers and repetitive phrases of Glass’ music accompany Reggio’s montages of natural landscapes, factory assembly lines, and chaotic city streets. Koyaanisqatsi means “life out of balance” in the language of an indigenous American tribe called the Hopi. In the original documentary, Glass’ music was paired with scenes of desolate streets in the South Bronx, the abandoned Pruitt-Igoe public housing in St. Louis, and ruined skyscrapers falling in slow motion. In my reinterpretation of Glass’ music, the imagery is now of Detroit in maps. The pace and events in the animation are tied to the structure of the music. As the volume and speed of the music increase and decrease, so too does the growth and decline of Detroit.

Population Changes to Detroit Over Time

Hover over infographic for details of each census year.

.

The influx of Black people during the Great Migration and the outflow of cars from Detroit’s factories reshaped the city’s built environment and the American public’s perception of Detroit. Detroit is now thought of as a majority-Black city surrounded by majority-White suburbs. Today, 83% of Detroit’s population is Black, and only 11% is White. But the graph above shows that Detroit was majority-White until the 1980 census. For most of its history, Detroit was 95 to 99% White. Today, the majority of the metro region’s population lives in the suburbs that surround Detroit. But until the 1960 census, the majority of the population lived within the city limits. Today, Detroit is so reliant on the car that it has no commuter rail network, no subways, and limited public transportation options. But until the 1950s demolition of Detroit’s light rail network, a majority of residents lived within walking distance of a light rail station for commuting. Detroit’s demographics, suburban sprawl, and transportation options have all flipped in the past century. From a high-density, transportation rich, and majority-White city in 1920, Detroit has become a low-density, transportation poor, and majority-Black city in 2020.
A lot of people say Detroit has terrible public transit design. But from the perspective of car companies, the real estate lobby, and fearful Whites, the system does exactly what it was intended to do: to segregate and divide our country by covert means long after Jim Crow officially “ended.” Failure by design. The failure of Detroit is, in large part, planned and a consequence of government policy decisions that: prioritize suburban growth over urban development; benefit suburban Whites over urban Blacks; and encourage private cars at the expense of public transit.
As the Detroit Evolution Animation plays, the map key on the lower right hand corner indicates Detroit’s demographics at each decade in history. Try to link changes to demographics with changes to the urban form. Ask yourself the questions: How were technology, transportation, and demographic changes imprinted on the built environment? How does the built environment, in turn, shape urban and suburban life?

The history of New Jersey suburbs as told through five data visualizations

.

View of the city from the suburbs, author’s panoramic drawing of suburbs with urban skyline in the distance

.

“The state of New Jersey offers an ideal setting in which to analyze the distinctive residential landscape of mass suburbia. [….] In time, 70 percent of the state’s total land area would qualify as suburban, so that by the turn of the twenty-first century New Jersey and Connecticut shared the distinction of being the nation’s most suburbanized states.”

.

– Lizabeth Cohen, “Residence: Inequality in Mass Suburbia” in A Consumer’s Republic, p. 197.

.

Northern New Jersey has long been central to the history of America’s suburban growth. From America’s oldest suburban developments to its most homogeneous to its most diverse, New Jersey’s 565 municipalities span the full portfolio of suburban living arrangements. New Jersey is unique in the sheer number of municipalities, each with its own elected leaders, school district, police, fire, and land use policies. As a result of inefficient and often duplicate public services in competing suburbs, New Jersey has some of the highest property taxes and cost of living in the country. This problem is not unique to New Jersey; it affects the country at large in dozens of other places. So the story of New Jersey makes for a powerful and revealing case study of larger trends in American suburban history.
This analysis examines New Jersey census data from 1940 to 2010. It is not the end point or a full analysis. Instead, each of these data visualizations plots a direction for future research. Telling history through maps and data reveals the history of a larger region and country, in ways that granular analysis of individual places cannot.

.

Method

With data from the US Census Bureau, I extracted details on the population of every New Jersey municipality from 1940 to 2010, the period of greatest suburban growth. With spatial data on municipal boundaries from the NJ Office of GIS, I plotted the census data onto the map of municipal boundaries. This allowed me to see spatial patterns and to produce heat maps of population change over time. The spatial data also revealed the surface area of each municipality, which allowed me to calculate the historical population density of each municipality as a function of municipal population divided by municipal surface area. You can browse all the data visualizations or download the open source data here from Tableau. These data visualizations represent analysis of about 13,560 data points for 565 municipalities over eight censuses.

The Berlin Evolution Animation

Abstract: The Berlin Evolution Animation visualizes the development of this city’s street network and infrastructure from 1415 to the present-day, using an overlay of historic maps. The resulting short film presents a series of 17 “cartographic snapshots” of the urban area at intervals of every 30-40 years. This process highlights Berlin’s urban development over 600 years, the rapid explosion of industry and population in the nineteenth-century, followed by the destruction and violence of two world wars and then the Cold War on Berlin’s urban fabric.

Methodology and Sources

I chose not to represent urban development before 1415 for three reasons: Firstly, there are too few accurate maps of the city before this time. Secondly, I needed to find accurate maps that had visual style consistent with later years, to enable easier comparison of development over time. Thirdly, the extent of urban development and population is limited (fewer than 10,000 Berliners).
There are numerous maps showing Berlin’s urban growth. Yet, few of them are drawn to the same scale, orientation and color palette. This makes it more difficult to observe changes to the city form over time. Fortunately, three map resources show this development with consistent style.
  1. The Historischer Atlas von Berlin (by Johann Marius Friedrich Schmidt) published 1835 represents Berlin in the selected years of: 1415, 1648, 1688, 1720, 1740, 1786. This atlas is available, free to view and download, at this link.
  2. After the year 1786, I rely on three books from cartographer Gerd Gauglitz:
    Berlin – Geschichte des Stadtgebietsin vier Karten
    Contains four maps of Berlin from 1806, 1920, 1988 and 2020. Read article.
    Berlin – Vier Stadtpläne im Vergleich
    Contains four maps from 1742, 1875, 1932 and 2017. Read article.
    Berlin – Vier Stadtpläne im VergleichErgänzungspläne
    Contains four maps from 1840,1953, 1988 and 1950. The last map from 1950 is speculative and shows Berlin as it would have looked had Germany won WWII and executed Albert Speer’s plans for rebuilding the city, named “Germania.” Read article.
    Gerd Gaulitz’s three map books can be purchased from Schropp Land & Karte.
  3. I also show the estimated extent of WWII bomb damage to Berlin. This map is sourced from an infographic dated 8 May 2015 in the Berliner Morgenpost. View original infographic. This infographic is, in turn, based on bombing maps produced by the British Royal Air Force during WWII (and Albert Speer’s c.1950 plan for Berlin).
Below is an interactive map I created of the Berlin Wall’s route and the four Allied occupation areas:

.

Population statistics in the 17 “cartographic snapshots” are estimates. The historical development of Berlin’s population is known for a few years. For other years, the population is estimated with regards to the two censuses between which the year of the “snapshot” falls.

California Waterscape: time-lapse history of water supply

California Waterscape animates the development of this state’s water delivery infrastructure from 1913 to 2019, using geo-referenced aqueduct route data, land use maps, and statistics on reservoir capacity. The resulting film presents a series of “cartographic snapshots” of every year since the opening of the Los Angeles Aqueduct in 1913. This process visualizes the rapid growth of this state’s population, cities, agriculture, and water needs.

Dams and Reservoirs

^ Created with open data from the US Bureau of Transportation Statistics and visualized in Tableau Public. This map includes all dams in California that are “50 feet or more in height, or with a normal storage capacity of 5,000 acre-feet or more, or with a maximum storage capacity of 25,000 acre-feet or more.” Dams are georeferenced and sized according to their storage capacity in acre-feet. One acre-foot is the amount required to cover one acre of land to a depth of one foot (equal to 325,851 gallons or 1.233 ● 10liters). This is the unit of measurement California uses to estimate water availability and use.

.

.

Aqueducts and Canals

^ Created with open data from the California Department of Water Resources, with additional water features manually added in QGIS and visualized in Tableau Public. All data on routes, lengths, and years completed is an estimate. This map includes all the major water infrastructure features; it is not comprehensive of all features.

 

Method and Sources

The most important data sources consulted are listed below:

This map excludes the following categories of aqueducts and canals:

  • Features built and managed by individual farmers and which extend for a length of only a few hundred feet. These features are too small and numerous to map for the entire state and to animate by their date completed. This level of information does not exist or is too difficult to locate.
  • Features built but later abandoned or demolished. This includes no longer extant aqueducts built by Spanish colonists, early American settlers, etc.
  • Features created by deepening, widening, or otherwise expanding the path of an existing and naturally flowing waterway. Many California rivers and streams were dredged and widened to become canals, and many more rivers turned into “canals” remain unlined along their path. Determining the construction date for these semi-natural features is therefore difficult. So, for the purposes of simplicity and to aid viewers in seeing only manmade water features, these water features are excluded.

Here Grows New York City

Music: “The Language of Cities” by Maserati

1. The Animation

Here Grows New York visually animates the development of this city’s street grid and environment from 1609 to the present day, using geo-referenced road network data, historic maps, and geological surveys. The resulting short film presents a series of “cartographic snapshots” of the built-up environment at intervals of every 20 to 30 years in history. This process highlights the organic spurts of growth and movement that typify New York’s and most cities’ development through time. The result is an abstract representation of urbanism.

3. Research Method

Several hundred maps in the digital archives of the New York Public Library and Library of Congress were analyzed to assemble this film. About 25 of these maps were then selected, downloaded, merged, stretched, and warped in a single document to align with each other. This provided a consistent scale and allowed easier comparison of differences between maps of different date. As the source files were all in different colors, scales, and designs, we created a single base map with unified graphics. The redrawing not only permits correcting errors in less accurate old maps but also provides a graphic representation that is consistent over time. This coherence allows the rate and trends in urban growth to be read more easily and compared between eras.

4. Conclusions and Analysis

This data visualization informs our analysis of the history of the New York City grid. This analysis reflects on the question: What can the built environment of Manhattan’s streets reflect about the evolving social and economic priorities of city planners and leaders? The long phases of urban growth and shifting transportation modes created distinctive road networks in Manhattan. The predominance of different forms of transport during each era also prompted changes to the location and dimensions of streets in response. Manhattan illustrates the evolution of these road networks over four centuries of near continuous growth. A plot can describe a street grid, as well as its builders’ story. This paper aims to tell this second plot, a story of urbanism.

Destruction of the James Street Commons: 1975-2020

This map (accurate as of April 2021) illustrates buildings demolished in one Newark neighborhood, the James Street Commons. When historians first considered this neighborhood for landmark status in 1975, there were 425 historic buildings. Even after earning landmark status in 1978, demolitions and urban decay continued. Rutgers, Edison Parking, St. Michael’s Hospital, and the New Jersey Institute of Technology have demolished dozens of old buildings, mostly to construct surface parking lots as an “interim” land use. It is time that the local and state governments be more proactive in preserving the city’s history.

An interactive map and photo project about Newark past and present, 1916 and today
Over the past century, Newark lost much of its architectural heritage and urban fabric. Along with cities like Chicago, Camden, and Detroit, Newark’s built environment evolved in response to population loss, urban renewal, and suburban growth. Explore the changing face of Newark in this interactive map with 150 comparative views of past and present streetscapes.
All historic images in this series are selected from the Newark Public Library’s collection of c.1916 postcards. All new photos were taken in 2016 to commemorate the 350th anniversary of Newark’s 1666 founding. My images capture Newark around 1916, at a moment just before American cities entered the automobile era. Postcards were a medium of communication popular in the early twentieth century. Many postcards feature views of Newark’s important landmarks; others are of mundane street scenes and structures. Through color corrections, careful editing, and marketing, these postcards present a curated and idealized view of Newark as postcard artists, business owners, and city planners desired the city to be remembered.

A city is more than its monuments, skyscrapers, and grand civic architecture. A city is a collection of structures, small and large, wood and stone, humble and grand. Newark has preserved its large monuments but has not maintained the cultural and urban fabric of its tenements, wood frame houses, warehouses, and single-family homes. Individually, these small-scale structures are humble and unimportant. Yet collectively, they constitute the living fabric of the city. Too many have been demolished in the name of progress, creating a cityscape radically different from the city’s height in the early twentieth century.

Downtown Newark

Downtown Newark in 1912 and in 2016. Note how the building at right, under construction in 1912, is now abandoned in 2016.

.

In the turn of the century view of downtown Newark, one sees the architectural styles popular at the time: stone and granite victorian and gothic structures. At left, is Prudential’s old headquarters demolished in 1956. At left, is Newark’s central post office. Unlike today, the postal service was central to the functioning of society and was often the most important structure in a town. This post office happens to be in the Romanesque Style popular in the 1880s. After the post office outgrew this structure and moved elsewhere in 1934, the structure was soon demolished in the 1940s to 1950s to construct an unimpressive dollar store. All buildings in this image are currently demolished.
