As places of dense habitation, cities have always required coordination and planning. City planning has involved the design and construction of large-scale infrastructure projects to provide basic necessities such as a water supply and drainage. By the 1850s, immigration and industrialization were fueling the rise of big cities, creating immense, collective problems of epidemics, slums, pollution, gridlock, and crime. From the 1850s to the 1900s, both local governments and utility companies responded to this explosive physical and demographic growth by constructing a “networked city” of modern technologies such as gaslight, telephones, and electricity. Building the urban environment also became a wellspring of innovation in science, medicine, and administration. In 1909–1910, a revolutionary idea—comprehensive city planning—opened a new era of professionalization and institutionalization in the planning departments of city halls and universities. Over the next thirty-five years, however, wars and depression limited their influence.
From 1945 to 1965, in contrast, represents the golden age of formal planning. During this unprecedented period of peace and prosperity, academically trained experts played central roles in the modernization of the inner cities and the sprawl of the suburbs. But the planners’ clean-sweep approach to urban renewal and the massive destruction caused by highway construction provoked a revolt of the grassroots. Beginning in the Watts district of Los Angeles in 1965, mass uprisings escalated over the next three years into a national crisis of social disorder, racial and ethnic inequality, and environmental injustice. The postwar consensus of theory and practice was shattered, replaced by a fragmented profession ranging from defenders of top-down systems of computer-generated simulations to proponents of advocacy planning from the bottom up. Since the late 1980s, the ascendency of public-private partnerships in building the urban environment has favored the planners promoting systems approaches, who promise a future of high-tech “smart cities” under their complete control.
On January 5, 2014—the fiftieth anniversary of President Lyndon Johnson’s launch of the War on Poverty—the New York Times asked a panel of opinion leaders a simple question: “Does the U.S. Need Another War on Poverty?” While the answers varied, all the invited debaters accepted the martial premise of the question—that a war on poverty had been fought and that eliminating poverty was, without a doubt, a “fight,” or a “battle.”
Yet the debate over the manner—martial or not—by which the federal government and public policy has dealt with the issue of poverty in the United States is still very much an open-ended one.
The evolution and development of the postwar American welfare state is a story not only of a number of “wars,” or individual political initiatives, against poverty, but also about the growth of institutions within and outside government that seek to address, alleviate, and eliminate poverty and its concomitant social ills. It is a complex and at times messy story, interwoven with the wider historical trajectory of this period: civil rights, the rise and fall of a “Cold War consensus,” the emergence of a counterculture, the Vietnam War, the credibility gap, the rise of conservatism, the end of “welfare,” and the emergence of compassionate conservatism. Mirroring the broader organization of the American political system, with a relatively weak center of power and delegated authority and decision-making in fifty states, the welfare model has developed and grown over decades. Policies viewed in one era as unmitigated failures have instead over time evolved and become part of the fabric of the welfare state.
The relationship between the car and the city remains complex and involves numerous private and public forces, innovations in technology, global economic fluctuations, and shifting cultural attitudes that only rarely consider the efficiency of the automobile as a long-term solution to urban transit. The advantages of privacy, speed, ease of access, and personal enjoyment that led many to first embrace the automobile were soon shared and accentuated by transit planners as the surest means to realize the long-held ideals of urban beautification, efficiency, and accessible suburbanization. The remarkable gains in productivity provided by industrial capitalism brought these dreams within reach and individual car ownership became the norm for most American families by the middle of the 20th century. Ironically, the success in creating such a “car country” produced the conditions that again congested traffic, raised questions about the quality of urban (and now suburban) living, and further distanced the nation from alternative transit options. The “hidden costs” of postwar automotive dependency in the United States became more apparent in the late 1960s, leading to federal legislation compelling manufacturers and transit professionals to address the long-standing inefficiencies of the car. This most recent phase coincides with a broader reappraisal of life in the city and a growing recognition of the material limits to mass automobility.
Changing foodways, the consumption and production of food, access to food, and debates over food shaped the nature of American cities in the 20th century. As American cities transformed from centers of industrialization at the start of the century to post-industrial societies at the end of the 20th century, food cultures in urban America shifted in response to the ever-changing urban environment. Cities remained centers of food culture, diversity, and food reform despite these shifts.
Growing populations and waves of immigration changed the nature of food cultures throughout the United States in the 20th century. These changes were significant, all contributing to an evolving sense of American food culture. For urban denizens, however, food choice and availability were dictated and shaped by a variety of powerful social factors, including class, race, ethnicity, gender, and laboring status. While cities possessed an abundance of food in a variety of locations to consume food, fresh food often remained difficult for the urban poor to obtain as the 20th century ended.
As markets expanded from 1900 to 1950, regional geography became a less important factor in determining what types of foods were available. In the second half of the 20th century, even global geography became less important to food choices. Citrus fruit from the West Coast was readily available in northeastern markets near the start of the century, and off-season fruits and vegetables from South America filled shelves in grocery stores by the end of the 20th century. Urban Americans became further disconnected from their food sources, but this dislocation spurred counter-movements that embraced ideas of local, seasonal foods and a rethinking of the city’s relationship with its food sources.
Gentrification is one of the most controversial issues in American cities today. But it also remains one of the least understood. Few agree on how to define it or whether it is boon or curse for cities. Gentrification has changed over time and has a history dating back to the early 20th century. Historically, gentrification has had a smaller demographic impact on American cities than suburbanization or immigration. But since the late 1970s, gentrification has dramatically reshaped cities like Seattle, San Francisco, and Boston. Furthermore, districts such as the French Quarter in New Orleans, New York City’s Greenwich Village, and Georgetown in Washington DC have had an outsized influence on the political, cultural, and architectural history of cities. Gentrification thus must be examined alongside suburbanization as one of the major historical trends shaping the 20th-century American metropolis.
During the 20th century, the black population of the United States transitioned from largely rural to mostly urban. In the early 1900s the majority of African Americans lived in rural, agricultural areas. Depictions of black people in popular culture often focused on pastoral settings, like the cotton fields of the rural South. But a dramatic shift occurred during the Great Migrations (1914–1930 and 1941–1970) when millions of rural black southerners relocated to US cities.
Motivated by economic opportunities in urban industrial areas during World Wars I and II, African Americans opted to move to southern cities as well as to urban centers in the Northeast, Midwest, and West Coast. New communities emerged that contained black social and cultural institutions, and musical and literary expressions flourished. Black migrants who left the South exercised voting rights, sending the first black representatives to Congress in the 20th century. Migrants often referred to themselves as “New Negroes,” pointing to their social, political, and cultural achievements, as well as their use of armed self-defense during violent racial confrontations, as evidence of their new stance on race.
The Immigration Act of 1924 was in large part the result of a deep political and cultural divide in America between heavily immigrant cities and far less diverse small towns and rural areas. The 1924 legislation, together with growing residential segregation, midcentury federal urban policy, and postwar suburbanization, undermined scores of ethnic enclaves in American cities between 1925 and the 1960s. The deportation of Mexicans and their American children during the Great Depression, the incarceration of West Coast Japanese Americans during World War II, and the wartime and postwar shift of so many jobs to suburban and Sunbelt areas also reshaped many US cities in these years. The Immigration Act of 1965, which enabled the immigration of large numbers of people from Asia, Latin America, and, eventually, Africa, helped to revitalize many depressed urban areas and inner-ring suburbs. In cities and suburbs across the country, the response to the new immigration since 1965 has ranged from welcoming to hostile. The national debate over immigration in the early 21st century reflects both familiar and newer cultural, linguistic, religious, racial, and regional rifts. However, urban areas with a history of immigrant incorporation remain the most politically supportive of such people, just as they were a century ago.
Post-1945 immigration to the United States differed fairly dramatically from America’s earlier 20th- and 19th-century immigration patterns, most notably in the dramatic rise in numbers of immigrants from Asia. Beginning in the late 19th century, the U.S. government took steps to bar immigration from Asia. The establishment of the national origins quota system in the 1924 Immigration Act narrowed the entryway for eastern and central Europeans, making western Europe the dominant source of immigrants. These policies shaped the racial and ethnic profile of the American population before 1945. Signs of change began to occur during and after World War II. The recruitment of temporary agricultural workers from Mexico led to an influx of Mexicans, and the repeal of Asian exclusion laws opened the door for Asian immigrants. Responding to complex international politics during the Cold War, the United States also formulated a series of refugee policies, admitting refugees from Europe, the western hemisphere, and later Southeast Asia. The movement of people to the United States increased drastically after 1965, when immigration reform ended the national origins quota system. The intricate and intriguing history of U.S. immigration after 1945 thus demonstrates how the United States related to a fast-changing world, its less restrictive immigration policies increasing the fluidity of the American population, with a substantial impact on American identity and domestic policy.
Mass transit has been part of the urban scene in the United States since the early 19th century. Regular steam ferry service began in New York City in the early 1810s and horse-drawn omnibuses plied city streets starting in the late 1820s. Expanding networks of horse railways emerged by the mid-19th century. The electric streetcar became the dominant mass transit vehicle a half century later. During this era, mass transit had a significant impact on American urban development. Mass transit’s importance in the lives of most Americans started to decline with the growth of automobile ownership in the 1920s, except for a temporary rise in transit ridership during World War II. In the 1960s, congressional subsidies began to reinvigorate mass transit and heavy-rail systems opened in several cities, followed by light rail systems in several others in the next decades. Today concerns about environmental sustainability and urban revitalization have stimulated renewed interest in the benefits of mass transit.
By serving travelers and commerce, roads and streets unite people and foster economic growth. But as they develop, roads and streets also disrupt old patterns, upset balances of power, and isolate some as they serve others. The consequent disagreements leave historical records documenting social struggles that might otherwise be overlooked. For long-distance travel in America before the middle of the 20th century, roads were generally poor alternatives, resorted to when superior means of travel, such as river and coastal vessels, canal boats, or railroads were unavailable. Most roads were unpaved, unmarked, and vulnerable to the effects of weather. Before the railroads, for travelers willing to pay the toll, rare turnpikes and plank roads could be much better. Even in towns, unpaved streets were common until the late 19th century, and persisted into the 20th. In the late 19th century, rapid urban growth, rural free delivery of the mails, and finally the proliferation of electric railways and bicycling contributed to growing pressure for better roads and streets. After 1910, the spread of the automobile accelerated the trend, but only with great controversy, especially in cities. Partly in response to the controversy, advocates of the automobile organized to promote state and county motor highways funded substantially by gasoline taxes; such roads were intended primarily for motor vehicles. In the 1950s, massive federal funds accelerated the trend; by then, motor vehicles were the primary transportation mode for both long and short distances. The consequences have been controversial, and alternatives have been attracting growing interest.
