The Death and Life of Great American Cities is a 1961 book by writer and activist Jane Jacobs. The book is a critique of 1950s urban planning policy, which it holds responsible for the decline of many city neighborhoods in the United States. The book is Jacobs' best-known and most influential work.
Jacobs was a critic of "rationalist" planners of the 1950s and 1960s, especially Robert Moses, as well as the earlier work of Le Corbusier. She argued that urban planning should prioritize the needs and experiences of residents, and modernist urban planning overlooked and oversimplified the complexity of human lives in diverse communities. She opposed large-scale urban renewal programs that affected entire neighborhoods and built freeways through inner cities. She instead advocated for dense mixed-use development and walkable streets, with the "eyes on the street" of passers-by helping to maintain public order. She suggested preserving the existing city fabric, including old buildings and established communities.
Orthodox urbanism Jacobs begins the work with a blunt statement: "This book is an attack on current city planning and rebuilding." She describes a trip to Boston's North End neighborhood in 1959, finding it friendly, safe, vibrant and healthy, and contrasting her experience against her conversations with elite planners and financiers in the area, who lament it as a "terrible slum" in need of renewal. Branding the mainstream theory of cities as an "elaborately learned superstition" that had now penetrated the thinking of planners, bureaucrats, and bankers in equal measure, she briefly traces the origins of this "orthodox urbanism."
Description In summarizing the development of contemporary city planning theory, she begins with the Garden city movement of Ebenezer Howard. Garden City was conceived as a new master-planned form, a self-sufficient town removed from the noise and squalor of late 19th century London, ringed by agriculture green belts, with schools and housing surrounding a highly prescribed commercial center. The Garden City would allow a maximum of 30,000 residents in each town, and called for a permanent public authority to carefully regulate land use and ward off the temptation to increase commercial activity or population density. Industrial factories were allowed on the periphery, provided they were masked behind green spaces. The Garden City concept was first embodied in the UK by the development of Letchworth and Welwyn Garden City, and in the US suburb of Radburn, NJ.
Jacobs tracks Howard's influence through American luminaries Lewis Mumford, Clarence Stein, Henry Wright, and Catherine Bauer, a collection of thinkers that Bauer referred to as "Decentrists." The Decentrists proposed to use regional planning as a means to ameliorate the woes of congested cities, attracting residents to a new life in lower-density fringes and suburbs and thereby thinning out the crowded urban core. Jacobs highlights the anti-urban biases of the Garden City advocates and the Decentrists, especially their shared intuitions that communities should be self-contained units; that commingled land use created a chaotic, unpredictable, and negative environment; that the street was a bad locus for human interactions; that houses should be turned away from the street toward sheltered green spaces; that super-blocks fed by arterial roads were superior to small blocks with overlapping cross-roads; that any significant details should be dictated by permanent plan rather than shaped by organic dynamism; and that population density should be discouraged, or at least disguised to create a sense of isolation.
Jacobs continues her survey of orthodox urbanism with Le Corbusier, whose Radiant City concept envisioned twenty-four towering skyscrapers within a Great Park. Superficially at odds with the low-rise, low-density ideals of the Decentrists, Le Corbusier presented his vertical city, with its 1,200 inhabitants per acre, as a way of extending the primary Garden City concepts – the super-block, regimented neighborhood planning, easy automobile access, and the insertion of large grassy expanses to keep pedestrians off the streets – into the city itself, with the explicit goal of reinventing stagnant downtowns. Jacobs concludes her introduction with a reference to the City Beautiful movement, which dotted downtown areas with civic centers, baroque boulevards, and new monument parks. These efforts borrowed concepts from other contexts, such as single-use public space disconnected from natural walking routes and the imitation of the exposition grounds at the World's Fair in Chicago.

Jacobs' critique Jacobs admits that the ideas of the Garden City and the Decentrists made sense on their own terms: a suburban town appealing to privacy-oriented, automobile-loving personalities should tout its green space and low-density housing. Jacobs' anti-orthodox frustration stems from the fact that their anti-urban biases somehow became an inextricable part of the mainstream academic and political consensus on how to design cities themselves, enshrined in course curricula and federal and state legislation affecting, inter alia, housing, mortgage financing, urban renewal, and zoning decisions. "This is the most amazing event in the whole sorry tale: that finally people who sincerely wanted to strengthen great cities should adopt recipes frankly devised for undermining their economies and killing them."
She is less sympathetic toward Le Corbusier, noting with dismay that the dream city, however impractical and detached from the actual context of existing cities, "was hailed deliriously by architects, and has gradually been embodied in scores of projects, ranging from low-income public housing to office building projects." She expresses further concern that, in seeking to avoid becoming contaminated by "the workaday city," isolated City Beautiful efforts dismally failed to attract visitors, were prone to unsavory loitering and dispirited decay, and ironically hastened the pace of urban demise.
The significance of sidewalks Jacobs frames the sidewalk as a central mechanism in maintaining the order of the city. "This order is all composed of movement and change, and although it is life, not art, we may fancifully call it the art form of the city and liken it to the dance." To Jacobs, the sidewalk is the quotidian stage for an "intricate ballet in which the individual dancers and ensembles all have distinctive parts which miraculously reinforce each other and compose an orderly whole."
Jacobs posits cities as fundamentally different from towns and suburbs principally because they are full of strangers. More precisely, the ratio of strangers to acquaintances is necessarily lopsided everywhere one goes in the city, even outside their doorstep, "because of the sheer number of people in small geographical compass." A central challenge of the city, therefore, is to make its inhabitants feel safe, secure, and socially integrated in the midst of an overwhelming volume of rotating strangers. The healthy sidewalk is a critical mechanism for achieving these ends, given its role in preventing crime and facilitating contact with others.
Jacobs emphasizes that city sidewalks should be considered in combination with physical environment surrounding sidewalks. As she put it, "A city sidewalk by itself is nothing. It is an abstraction. It means something only in conjunction with the buildings and other uses that border it, or border other sidewalks very near it."
Safety Jacobs argues that city sidewalks and people who use sidewalks actively participate in fighting against disorder and preserving civilization. They are more than "passive beneficiaries of safety or helpless victims of danger". The healthy city sidewalk does not rely on constant police surveillance to keep it safe, but on an "intricate, almost unconscious, network of voluntary controls and standards among the people themselves, and enforced by the people themselves." Noting that a well-used street is apt to be relatively safe from crime, while a deserted street is apt to be unsafe, Jacobs suggests that a dense volume of human users deters most violent crimes, or at least ensures a critical mass of first responders to mitigate disorderly incidents. The more bustling a street, the more interesting it is for strangers to walk along or watch from inside, creating an ever larger pool of unwitting deputies who might spot early signs of trouble. In other words, healthy sidewalks transform the city's high volume of strangers from a liability to an asset.
The self-enforcing mechanism is especially strong when the streets are supervised by their "natural proprietors," individuals who enjoy watching street activity, feel naturally invested in its unspoken codes of conduct, and are confident that others will support their actions if necessary. They form the first line of defense for administering order on the sidewalk, supplemented by police authority when the situation demands it. She further concludes three necessary qualities that a city street needs to maintain safety: 1) a clear demarcation between public and private space; 2) eyes upon the street and sufficient buildings facing streets; 3) continuous eyes on the street to guarantee effective surveillance. Over time, a considerable number of criminological studies have applied the concept of "eyes on the street" in crime prevention.
Jacobs contrasts the natural proprietors to the "birds of passage", the transient and uninvested block dwellers who "have not the remotest idea of who takes care of their street, or how." Jacobs warns that, while neighborhoods can absorb a large number of these individuals, "if and when the neighborhood finally becomes them, they will gradually find the streets less secure, they will be vaguely mystified about it, and...they will drift away."
Jacobs draws a parallel between empty streets and the deserted corridors, elevators, and stairwells in high-rise public housing projects. These "blind-eyed" spaces, modeled after the upper-class standards for apartment living but lacking the amenities of access control, doormen, elevator men, engaged building management, or related supervisory functions, are ill-equipped to handle strangers, and therefore the presence of strangers becomes "an automatic menace." They are open to the public but shielded from public view, and thus "lack the checks and inhibitions exerted by eye-policed city streets," becoming flash points for destructive and malicious behavior. As residents feel progressively unsafe outside their apartments, they increasingly disengage from the life of the building and exhibit tendencies of birds of passage. These troubles are not irreversible. Jacobs claims that a Brooklyn project successfully reduced vandalism and theft by opening the corridors to public view, equipping them as play spaces and narrow porches, and even letting tenants use them as picnic grounds.
