North America
Boston and New York spawned the first major suburbs. Boston's streetcar lines and Manhattan's railroad lines made commuting possible.[23] No metropolitan area in the world was as well served by commuter rail lines at the turn of the century as New York, and it was the rail lines to Westchester from the Grand Central Terminal commuter hub that enabled its development. Westchester's true importance in the history of American suburbanization is due to the development of upper-middle-class towns, such as Carsdale), New Rochelle, and Rye, which served thousands of Manhattan businessmen and executives.[24]
The suburban population in North America exploded during the post-World War II economic expansion. Returning veterans who wanted to start a stable life moved en masse to the suburbs. Levittown") developed as a major prototype of mass housing. Due to the influx of people into these suburban areas, the number of shopping centers began to increase as suburban America took shape. These shopping centers helped supply goods and services to the growing urban population. The purchase of different goods and services in a central location without having to travel to multiple locations, helped maintain shopping centers as a component of these newly designed suburbs that were booming in population. Television contributed to the rise of shopping centers due to the increase in advertising on television, in addition to the desire for products to be shown in suburban life on various television programs. Another factor that led to the rise of these shopping centers was the construction of many highways. The Highway Act of 1956 helped finance the construction of 64,000 kilometers throughout the country by having $26 billion for their use, which helped link many more to these shopping centers with ease.[25] These newly created shopping centers Built, which were often large buildings filled with multiple stores, and services, were being used for more than just shopping, but as a place of leisure and a meeting point for those living within suburban America at this time. These centers prospered by offering goods and services to the growing populations of suburban America. In 1957, 940 shopping centers were built and this number more than doubled in 1960 to meet the demand of these densely populated areas. populated.[26].
Very little housing was built during the Great Depression and World War II, except for emergency accommodation near war industries. Overcrowding and inadequate apartments were the common condition. Some suburbs had developed around large cities, where there was rail transportation to downtown jobs. However, the true growth of the suburbs depended on the availability of automobiles, highways, and cheap housing. The population had grown, and families' stash of savings had accumulated money for down payments, cars, and appliances. The product was a great real estate boom. While in the decade from 1930 to 1945 an average of 316,000 new non-agricultural homes should have been built, between 1946 and 1955 1,450,000 were built annually.[27] The G.I. Bill guaranteed low-cost loans for veterans, with very low down payments, and low interest rates. With 16 million eligible veterans, the opportunity to buy a home was suddenly within reach. In 1947 alone, 540,000 veterans bought one; Its average price was $7,300. The construction industry kept prices low through standardization; For example, the standardization of the sizes of kitchen cabinets, refrigerators, and stoves allowed for the mass production of kitchen furniture. Developers bought empty lots on the outskirts of town, installed townhouses based on a handful of designs, and provided streets and public services, or local public officials rushed to build schools. The most famous development was Levittown, on Long Island, east of New York City. It offered a new house for $1,000 down and $70 a month; it had three bedrooms, a fireplace, a gas stove and oven, and a lot. 75-by-100-foot landscaped garden, all for a total price of $10,000. Veterans could get one with a much smaller down payment.[29]
At the same time, African Americans were moving rapidly north and west in search of better jobs and educational opportunities than they had in the segregated South. Its arrival en masse in the cities of the North and West, in addition to being followed by racial riots in several large cities such as Philadelphia, Los Angeles, Detroit, Chicago, and Washington D.C., further stimulated suburban migration of whites. The growth of suburbs was facilitated by the development of zoning laws, redlining, and numerous innovations in transportation. Redlining and other discriminatory measures incorporated into federal housing policy furthered racial segregation in the postwar United States, for example by refusing to insure mortgages in and around African-American neighborhoods. The government's efforts were primarily intended to provide housing for middle- or lower-middle-class white families. African Americans and other people of color remained largely concentrated within pockets of declining urban poverty, creating a phenomenon known as white flight.
After World War II, the availability of FHA loans stimulated a housing boom in American suburbs. In older cities in the northeastern United States, streetcar suburbs originally developed along train or streetcar lines that could move workers to and from city centers where jobs were located. This practice gave rise to the term "commuter town", meaning that most daytime commercial activity took place in the city, and the working population left it at night to go home to sleep.
The economic growth of the United States encouraged the suburbanization of American cities, requiring enormous investments in new infrastructure and housing. Consumption patterns were also changing at this time, as purchasing power was increasingly stronger and accessible to a greater number of families. Suburban housing also brought with it needs for products that were not needed in urban neighborhoods, such as lawnmowers and automobiles. During this era, shopping centers were developed near the suburbs to meet the needs of consumers and their car-dependent lifestyle.[31].
Zoning laws also contributed to the location of residential areas outside the city center, creating large areas or "zones" in which only residential buildings were permitted. These suburban residences are built on larger lots than in the city center. For example, the lot size for a residence in Chicago typically has a depth of 125 feet (38.1 m),[32] while the width can vary from 14 feet (4.3 m) wide for a townhouse to 45 feet (13.7 m) wide for a large detached house. In the suburbs, where detached houses are the norm, lots may be 85 feet (25.9 m) wide by 115 feet (35.1 m) deep, as in the Chicago suburb of Naperville. In other areas of the city, industrial and commercial buildings were segregated.
Along with suburbanization, many companies began to locate their offices and other facilities in the outer areas of cities, leading to the increase in the density of older suburbs and the growth of lower-density suburbs even further from urban centers. An alternative strategy is the deliberate design of "new cities" and the protection of the green belt around cities. Some social reformers attempted to combine the best of both concepts in the garden city movement.[33].
In the United States, 1950 was the first year in which more people lived in the suburbs than elsewhere.[34] In the US, the development of skyscrapers and the strong inflation of downtown real estate prices also led to downtowns becoming more devoted to business, thus pushing residents out of the city center.
