Downtown
Downtown is a term primarily used in American and Canadian English to refer to a city's sometimes commercial, cultural and often the historical, political, and geographic heart. It is often synonymous with its central business district. It may also be a center for shopping and entertainment. Downtowns typically contain a small percentage of a city's employment but are concentrated in services, including high-end services. Sometimes, smaller downtowns include lower population densities and lower incomes than nearby suburbs. It is often distinguished as a hub of public transit and culture.
History
Early downtowns and uptowns
The Oxford English Dictionary's first citation for "down town" or "downtown" dates to 1770, in reference to the center of Boston. Some have posited that the term "downtown" was coined in New York City, where it was in use by the 1830s to refer to the original settlement, or town, at the southern tip of the island of Manhattan. As the town of New York grew into a city, the only direction it could grow on the island was toward the north, proceeding upriver from the original settlement, the "up" and "down" terminology coming from the customary map design in which up was north and down was south. Thus, anything north of the original town became known as "uptown", and was generally a residential area, while the original town – which was also New York's only major center of business at the time – became known as "downtown".File:256 BROADWAY, LOOKING NORTH FROM BARCLAY STREET.

During the late 19th century, the term was gradually adopted by cities across the United States to refer to the historical core of the city, which was most often the same as the commercial heart of the city. "Uptown" also spread, but to a much lesser extent. In both cases, though, the directionality of both words was lost, so that a Bostonian might refer to going "downtown", even though it was north of where they were.
Downtown lay to the south in Detroit, but to the north in Cleveland, to the east in St. Louis, and to the west in Pittsburgh. In Boston, a resident pointed out in 1880, downtown was in the center of the city. Uptown was north of downtown in Cincinnati, but south of downtown in New Orleans and San Francisco.
Notably, "downtown" was not included in dictionaries as late as the 1880s. But by the early 1900s, "downtown" was clearly established as the proper term in American English for a city's central business district, although the word was virtually unknown in Britain and Western Europe, where expressions such as "city centre", "el centro", "das Zentrum", etc are used. Even as late as the early part of the 20th century, English travel writers felt it necessary to explain to their readers what "downtown" meant.
Although American downtowns lacked legally defined boundaries, and were often parts of several of the wards that most cities used as their basic functional district, locating the downtown area was not difficult, as it was the place where all the street railways and elevated railways converged, and – at least in most places – where the railroad terminals were. It was the location of the great department stores and hotels, as well as that of theaters, clubs, cabarets, and dance halls, and where skyscrapers were built once that technology was perfected. It was also frequently, at first, the only part of a city that was electrified. It was also the place where street congestion was the worst, a problem for which a solution was never really found.
But most of all, downtown was the place where the city did its business. Inside its small precincts, sometimes as small as several hundred acres, the majority of the trading, selling, and purchasing – retail and wholesale – in the entire area would take place. There were hubs of business in other places around the city and its environs, but the downtown area was the chief one, truly the central business district. And as more and more business was done downtown, those who had their homes there were gradually pushed out, selling their property and moving to quieter residential areas uptown.
Skyscrapers
The skyscraper would become the hallmark of the downtown area. Prior to the invention of the elevator – and later the high-speed elevator – buildings were limited in height to about six stories, which was a de facto limit set by the amount of stairs it was assumed that people would climb, but with the elevator, that limit was shattered, and buildings began to be constructed up to about sixteen stories. What limited them then was the thickness of the masonry needed at the base to hold the weight of the building above it. As the buildings got taller, the thickness of the masonry and the space needed for elevators did not allow for sufficient rentable space to make the building profitable. What shattered that restriction was the invention of first the iron- and then the steel frame building, in which the building's load was carried by an internal metal frame skeleton, from which the masonry – and later glass – simply hung, without carrying any weight.Although first used in Chicago, the steel-framed skyscraper caught on most quickly in New York City in the 1880s, and from there spread to most other American cities in the 1890s and 1900s. The apparent lack of a height limitation of this type of building set off a fervent debate over whether their height should be restricted by law, with proponents and opponents of height limits bringing out numerous arguments in favor of their position. The question of height limits also had a profound implication for the nature of downtown itself: would it continue to be a concentrated core, or as it grew, would height limits force it to spread out into a larger area. In the short run, the proponents of height limits were successful in their efforts. By the 1910s, most of the large and medium-sized cities had height limits in effect, although New York, Philadelphia, Detroit, Pittsburgh, and Minneapolis were notable exceptions.
Zoning
Ultimately, it was not simple height limits that restricted skyscrapers, but they were limited by comprehensive zoning laws which set up separate requirements for different parts of a city. Zoning rules would regulate not only height, but also a building's volume, the percentage of the lot used, and the amount of light the building blocked. Zoning regulations sometimes encouraged setbacks to reduce a building's bulk by allowing additional height per foot of setback – the exact amount depending on what zone the building was in. The ultimate effect of setbacks is to increase the sunlight and visible sky at street level. New York City was the first to do this, with the 1916 Zoning Resolution, which was prompted in large part by the construction of the Equitable Building in 1915. The Equitable Building was a 40-story building with straight sides and no setbacks, which raised fears of the downtown area becoming a maze of dark streets that never saw the sun. Worse yet, at least from a real estate perspective, this new building created 1.2 million square feet of office space, flooding into what was already a sluggish market. To many in the real estate industry, the zoning law was an example of a "reasonable restriction."Once New York had passed its law, other cities followed, although proposed zoning measures did meet stiff resistance in some places, often because of the inclusion of overly restrictive height limits, and sometimes because the entire concept of zoning was seen as undemocratic and bordering on socialism. Eventually, a model law, the Standard State Zoning Enabling Act of 1922 was drawn up for the guidance of cities wishing to enact zoning regulations, which are now part of virtually every American city.
Central business district
In the 20th century downtown zones were redeveloped with single-purpose office skyscrapers for commuting employees of companies. The typical downtown was no longer necessarily suitable for mixed-use housing, manufacturing, retail, and whatever else a human may want. In the early 20th century, a downtown area was defined as the business district of the American city. But beginning in the 1920s and 1930s, as cities continued to grow in size and population, rival business districts began to appear outside of downtown in outlying districts. This was the time when the term "central business district" began to appear as more-or-less synonymous with the downtown area. The phrase acknowledged the existence of other business districts in the city, but allocated to downtown the primacy of being "central", not only geographically, in many cities, but also in importance. And in many cases, the downtown area or central business district, itself began to grow, such as in Manhattan where the business district lower Manhattan and the newer one in midtown began to grow towards each other, or in Chicago, where downtown expanded from the Loop across the Chicago River to Michigan Avenue. In fact, the instability of downtown was a cause for concern for business and real estate interests, as the business district refused to stay where it had been, and shifted its location in response to numerous factors, although it generally stayed fairly compact – in the early 1930s even the largest took up less than 2% of the city's space, and most were significantly smaller – and remained the primary business district of the city.Real estate interests were particularly concerned about the tendency of downtown to move because the downtown area had by far the highest land values in each city. One commentator said that if Chicago's land values were shown as height on a relief map, the Loop would be equivalent to the peaks of the Himalayas compared to the rest of the city. In 1926, Chicago's central business district, which took up less than 1% of the city, had 20% of the city's land value. The same relationship was true in St. Louis in the mid-20s and Los Angeles in the early 1930s. So when a downtown area started to shift its location, some property owners were bound to lose a great deal of money, while others would stand to gain.
