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 August 4, 1942, the Mexican and U.S. governments launched the bi-national guest worker program, most commonly known as the Bracero Program. An estimated five million Mexican men between the ages of 19 and 45 separated from their families for three-to-nine-month contract cycles at a time, in anticipation of earning the prevailing U.S. wage this program had promised them. They labored in U.S. agriculture, railroad construction, and forestry, with hardly any employment protections or rights in place to support themselves and the families they had left behind in Mexico. The inhumane configuration and implementation of this program prevented most of these men and their families from meeting such goals. Instead, the labor exploitation and alienation that characterized this guest worker program and their program participation paved the way for, at best, fragile family relationships. This program lasted twenty-two years and grew in its expanse, despite its negative consequences, Mexican men and their families could not afford to settle for being unemployed in Mexico, nor could they pass up U.S. employment opportunities of any sort. The Mexican and U.S. governments’ persistently negligent management of the Bracero Program, coupled with their conveniently selective acknowledgement of the severity of the plight of Mexican women and men, consistently cornered Mexican men and their families to shoulder the full extent of the Bracero Program’s exploitative conditions and terms.
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.

American food in the twentieth and twenty-first centuries is characterized by abundance. Unlike the hardscrabble existence of many earlier Americans, the “Golden Age of Agriculture” brought the bounty produced in fields across the United States to both consumers and producers. While the “Golden Age” technically ended as World War I began, larger quantities of relatively inexpensive food became the norm for most Americans as more fresh foods, rather than staple crops, made their way to urban centers and rising real wages made it easier to purchase these comestibles.
The application of science and technology to food production from the field to the kitchen cabinet, or even more crucially the refrigerator by the mid-1930s, reflects the changing demographics and affluence of American society as much as it does the inventiveness of scientists and entrepreneurs. Perhaps the single most important symbol of overabundance in the United States is the postwar Green Revolution. The vast increase in agricultural production based on improved agronomics, provoked both praise and criticism as exemplified by Time magazine’s critique of Rachel Carson’s Silent Spring in September 1962 or more recently the politics of genetically modified foods.
Reflecting that which occurred at the turn of the twentieth century, food production, politics, and policy at the turn of the twenty-first century has become a proxy for larger ideological agendas and the fractured nature of class in the United States. Battles over the following issues speak to which Americans have access to affordable, nutritious food: organic versus conventional farming, antibiotic use in meat production, dissemination of food stamps, contraction of farm subsidies, the rapid growth of “dollar stores,” alternative diets (organic, vegetarian, vegan, paleo, etc.), and, perhaps most ubiquitous of all, the “obesity epidemic.” These arguments carry moral and ethical values as each side deems some foods and diets virtuous, and others corrupting. While Americans have long held a variety of food ideologies that meld health, politics, and morality, exemplified by Sylvester Graham and John Harvey Kellogg in the nineteenth and early twentieth centuries, among others, newer constructions of these ideologies reflect concerns over the environment, rural Americans, climate change, self-determination, and the role of government in individual lives. In other words, food can be used as a lens to understand larger issues in American society while at the same time allowing historians to explore the intimate details of everyday life.
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.
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.
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.
In 1944 President Franklin D. Roosevelt’s State of the Union address set out what he termed an “economic Bill of Rights” that would act as a manifesto of liberal policies after World War Two. Politically, however, the United States was a different place than the country that had faced the ravages of the Great Depression of the 1930s and ushered in Roosevelt’s New Deal to transform the relationship between government and the people. Key legacies of the New Deal, such as Social Security, remained and were gradually expanded, but opponents of governmental regulation of the economy launched a bitter campaign after the war to roll back labor union rights and dismantle the New Deal state.
Liberal heirs to FDR in the 1950s, represented by figures like two-time presidential candidate Adlai Stevenson, struggled to rework liberalism to tackle the realities of a more prosperous age. The long shadow of the U.S. Cold War with the Soviet Union also set up new challenges for liberal politicians trying to juggle domestic and international priorities in an era of superpower rivalry and American global dominance. The election of John F. Kennedy as president in November 1960 seemed to represent a narrow victory for Cold War liberalism, and his election coincided with the intensification of the struggle for racial equality in the United States that would do much to shape liberal politics in the 1960s. After his assassination in 1963, President Lyndon Johnson launched his “Great Society,” a commitment to eradicate poverty and to provide greater economic security for Americans through policies such as Medicare. But his administration’s deepening involvement in the Vietnam War and its mixed record on alleviating poverty did much to taint the positive connotations of “liberalism” that had dominated politics during the New Deal era.
