Suburbanization in the context of Urban sprawl

In urban planning, a historic core city or central city is the municipality with the largest 1940 population in the present metropolitan area (metropolitan statistical area). This term was retired by the US census bureau and replaced by the term principal city, which can include historic core cities and post-WWII cities. Metropolitan areas were no longer considered monocentric, but polycentric due to suburbanization of employment. A historic core city is not to be confused with the core of a metropolitan area which is defined as an urban area with a population of over 50,000 by the US census bureau.

Historic core cites in the United States often have higher detached single family housing rates, lower density, and fewer jobs than surrounding satellite cities and suburbs. A central city is usually the first settlement established in an urban region, years before the outlying districts came into existence. These cities typically contain less economic activity and more crime than their surrounding areas. Central cities often form the regional downtowns of metro areas. The term is used mainly in US context, although since the 1970s it has also become relatively common in Canada and, to a lesser extent, Europe and Australia.

Counterurbanization, ruralization, or deurbanization is a demographic and social process in which people move from urban areas to rural areas. It, as suburbanization, is inversely related to urbanization, and first occurs as a reaction to inner-city deprivation. Recent research has documented the social and political drivers of counterurbanization and its impacts in China and other developing countries which are undergoing a process of mass urbanization. Counterurbanization is one of the causes that can lead to shrinking cities.

While counterurbanization manifests differently across the world, all forms revolve around the central idea of migration movement from a populated location to a less populated location. Clare J.A. Mitchell, an associate professor in the Department of Geography at the University of Waterloo, argues that in Europe, counterurbanization involves a type of migration leading to deconcentration of one area to another that is beyond suburbanization or metro decentralization. Mitchell categorizes counterurbanization into three sub-types: ex-urbanization, displaced-urbanization, and anti-urbanization.

In the United States, a metropolitan statistical area (MSA) is a geographical region with a relatively high population density at its core and close economic ties throughout the region. Such regions are not legally incorporated as a city or town would be and are not legal administrative divisions like counties or separate entities such as states. As a result, sometimes the precise definition of a given metropolitan area will vary between sources. The statistical criteria for a standard metropolitan area were defined in 1949 and redefined as a metropolitan statistical area in 1983.

Due to suburbanization, the typical metropolitan area is polycentric rather than being centered around a large historic core city such as New York City or Chicago. Some metropolitan areas include more than one large historic core city; examples include the Dallas–Fort Worth metroplex, Virginia Beach–Norfolk–Newport News (Hampton Roads), Riverside–San Bernardino (Inland Empire), and Minneapolis–Saint Paul (Twin Cities).

The demographics of Poland include population density, ethnicity, education level, the health of the populace, economic status, religious affiliations, and other aspects of the population.

As of 31 December 2024, the population of Poland was 37,489,000, while the usually resident population was 36,497,495. The population has exhibited a negative growth rate of −0.42% per year. The population density was 119 people per square kilometer. The proportion of the population residing in urban areas was 59%, a figure that has been declining as a consequence of suburbanization. The sex ratio was 107 women per 100 men, 112 per 100 in urban areas, and 101 per 100 in rural areas. The median age was over 43 years (nearly 42 years for males and 45 years for females).

New Urbanism is an urban design movement that promotes environmentally friendly habits by creating walkable neighbourhoods containing a wide range of housing and job types. It arose in the United States in the early 1980s, and has gradually influenced many aspects of real estate development, urban planning, and municipal land-use strategies. New Urbanism attempts to address the ills associated with urban sprawl and post-WWII suburban development.

New Urbanism is strongly influenced by urban design practices that were prominent until the rise of the automobile prior to World War II; it encompasses basic principles such as traditional neighborhood development (TND) and transit-oriented development (TOD). These concrete principles emerge from two organizing concepts or goals: building a sense of community and the development of ecological practices.

Cherry Hill is a township within Camden County, in the U.S. state of New Jersey. As a suburb of Philadelphia, the township is part of the South Jersey and Delaware Valley regions. Cherry Hill Township grew during the mid-20th century suburbanization, becoming one of the Delaware Valley's main commercial centers, including the Cherry Hill Mall. As of the 2020 United States census, the township's population was 74,553, making it the largest municipality of any type by population in the South Jersey region.

Bridgeport is the most populous city in the U.S. state of Connecticut and the fifth-most populous city in New England, with a population of 148,654 in 2020. Located in eastern Fairfield County at the mouth of the Pequonnock River on Long Island Sound, it is a port city 60 miles (97 km) from Manhattan and 40 miles (64 km) from The Bronx. It borders the towns of Trumbull to the north, Fairfield to the west, and Stratford to the east. Bridgeport and other towns in Fairfield County make up the Greater Bridgeport Planning Region, as well as the Bridgeport–Stamford–Norwalk–Danbury metropolitan statistical area, the second largest metropolitan area in Connecticut. The Bridgeport–Stamford–Norwalk–Danbury metropolis forms part of the New York metropolitan area.

Inhabited by the Paugussett Native American tribe until English settlement in the 1600s, Bridgeport was incorporated in 1821 as a town, and as a city in 1836. Showman P. T. Barnum was a resident of the city and served as the town's mayor (1871). Barnum built four houses in Bridgeport and housed his circus in town during winter. The city in the early 20th century saw an economic and population boom, becoming by all measures Connecticut's chief manufacturing city by 1905. Bridgeport was the site of the world's first mutual telephone exchange (1877), the first dental hygiene school (1949), and the first bank telephone bill service in the US (1981). Inventor Harvey Hubbell II invented the electric plug outlet in Bridgeport in 1912. The Frisbie Pie Company was founded and operated in Bridgeport. The world's first Subway restaurant opened in the city's North End in 1965. After World War II, industrial restructuring and suburbanization caused the loss of many large companies and affluent residents, leaving Bridgeport struggling with issues of poverty and violent crime.

Midlothian (/mɪdˈloʊθiən/ mid-LOH-thee-ən) is an unincorporated area and census-designated place in Chesterfield County, Virginia, United States. Settled as a coal town, Midlothian village experienced suburbanization effects and is now part of the western suburbs of Richmond, south of the James River in the Greater Richmond Region. Because of its unincorporated status, Midlothian has no formal government, and the name is used to represent the original small Village of Midlothian and a vast expanse of Chesterfield County in the northwestern portion of Southside Richmond served by the Midlothian post office.

The Village of Midlothian was named for the early 18th-century coal mining enterprises of the Wooldridge family. Incorporated in 1836, their Mid-Lothian Mining and Manufacturing Company employed free and enslaved people to do the deadly work of digging underground. Midlothian is the site of the first commercially-mined coal in the Colony of Virginia and North America.

Columbus (/kəˈlʌmbəs/, kə-LUM-bəs) is the capital and most populous city of the U.S. state of Ohio. With a population of 905,748 at the 2020 census, it is the 14th-most populous city in the U.S., second-most populous city in the Midwest (after Chicago), and third-most populous U.S. state capital (after Phoenix, Arizona, and Austin, Texas). The Columbus metropolitan area, with an estimated 2.23 million residents, is the largest metropolitan area entirely in Ohio and 32nd-largest metropolitan area in the U.S. Columbus is the county seat of Franklin County; it also extends into Delaware and Fairfield counties.

Columbus originated as several Native American settlements along the Scioto River. The first European settlement was Franklinton, now a city neighborhood, in 1797. Columbus was founded in 1812 at the confluence of the Scioto and Olentangy rivers and was named after Italian explorer Christopher Columbus. It was planned as the state capital due to its central location and officially became the capital in 1816. The city grew steadily through the 19th century as a transportation and industrial hub via the National Road, Ohio and Erie Canal, and several railroads. Starting in the 1950s, Columbus experienced rapid suburban growth, becoming Ohio's largest city by area and population by the early 1990s.

A multi-purpose stadium is a type of stadium designed to be easily used for multiple types of events. While any stadium could potentially host more than one type of sport or event, this concept usually refers to a design philosophy that stresses multifunctionality over speciality. It is used most commonly in Canada and the United States, where the two most popular outdoor team sports—Canadian football or American football and baseball—require radically different facilities. Football uses a rectangular field, while baseball is played on a diamond with a large outfield. Since Canadian football fields are larger than American ones, the design specifications for Canadian facilities are somewhat less demanding. The particular design to accommodate both is usually an oval, although some later designs use an octorad. While building stadiums in this manner allows sports teams and governments to share costs, it also presents some challenges.

In North America, multipurpose stadiums were primarily built during the 1960s and 1970s as shared home stadiums for Major League Baseball and National Football League or Canadian Football League teams. Some stadiums were renovated to allow multipurpose configurations during the 1980s. This type of stadium is associated with an era of suburbanization, in which many sports teams followed their fans out of large cities into areas with cheaper, more plentiful land. They were usually built near highways and had large parking lots, but were rarely connected to public transit. As multipurpose stadiums were rarely ideal for both sports usually housed in them, they had fallen out of favor by the 1990s, with the SkyDome (in Canada) that opened in 1989 being the last such stadium completed to accommodate baseball and football. With the completion of the Truman Sports Complex in Kansas City in 1973, a model for purpose-built stadiums was laid down. Since the Baltimore Orioles left the multi-purpose Memorial Stadium for the baseball-only Oriole Park at Camden Yards in 1992, most major league sports stadiums have been built specifically for one sport. However, some newer NFL stadiums (e.g. Seattle, Atlanta, Charlotte) have been built with consideration for the possible use of the stadium for Major League Soccer or international soccer, which has similar field dimensions to American football. Fields that are suitable for soccer are almost always equally suitable for either rugby code (rugby union or rugby league), and the 2031 Men's Rugby World Cup is expected to employ the same stadiums as the NFL and MLS.

Altamont Pass, formerly Livermore Pass, is a low mountain pass in the Diablo Range of Northern California between Livermore in the Livermore Valley and Tracy in the San Joaquin Valley. The name is actually applied to two distinct but nearby crossings of the range. The lower of the two, at an elevation of 741 ft (226 m), carries two railroad rights-of-way (ROWs) and Altamont Pass Road, part of the old Lincoln Highway and the original alignment of US 50 before it was bypassed in 1937. The bypass route travels over the higher summit, at 1,009 ft (308 m), and now carries Interstate 580, a major regional highway heavily congested by Central Valley suburbanization.

Of the two railroad lines through the old pass, one is still in use: the ex-Western Pacific line built in 1908 over the pass, which is sometimes known as the Altamont Corridor, now owned by Union Pacific. It carries freight trains as well as the Altamont Corridor Express, which gives its occasional name (ACE) and operates between Stockton, Livermore, Pleasanton, Fremont, and San Jose. The other and older right-of-way was the line built in 1869 with a 1,200-foot-long (370 m) summit tunnel by the original Western Pacific Railroad (1862–1870) as part of the transcontinental railroad. After 1879, when a sea level ferry crossing at the Carquinez Strait replaced the 1869 route, it remained in use for other purposes by the Southern Pacific. In 1984 it was abandoned and deeded to Alameda County by Southern Pacific Railroad in favor of trackage rights on the aforementioned ex-Western Pacific line.
