The median household income in 2022 was $ 78,740 (versus the U.S. national figure of $ 75,149), with family households having a median income of $ 126,292. The per capita income for

605-473: A $ 2.3 million bond issue to build the current city hall, which was designed by architect Alden B. Dow . The City Hall opened in 1963. In 1995, the building was renamed the Guy C. Larcom Jr. Municipal Building in honor of the longtime city administrator who championed the building's construction. During the 1960s and 1970s, the city gained a reputation as an important center for liberal politics. Ann Arbor also became

726-513: A 1956 vote, the city of East Ann Arbor merged with Ann Arbor to encompass the eastern sections of the city. In the past several decades, Ann Arbor has grappled with the effects of sharply rising land values, gentrification , and urban sprawl stretching into outlying countryside. On November 4, 2003, voters approved a greenbelt plan under which the city government bought development rights on agricultural parcels of land adjacent to Ann Arbor to preserve them from sprawling development. Since then,

847-512: A Roman Catholic law school established by Domino's Pizza founder Tom Monaghan , opened in northeastern Ann Arbor, but the school moved to Ave Maria, Florida in 2009, and the Thomas M. Cooley Law School acquired the former Ave Maria buildings for use as a branch campus. City Historically, city dwellers have been a small proportion of humanity overall, but following two centuries of unprecedented and rapid urbanization , more than half of

968-573: A central area containing buildings with special economic, political, and religious significance. Archaeologists refer to this area by the Greek term temenos or if fortified as a citadel . These spaces historically reflect and amplify the city's centrality and importance to its wider sphere of influence . Today cities have a city center or downtown , sometimes coincident with a central business district . Cities typically have public spaces where anyone can go. These include privately owned spaces open to

1089-665: A central authority. The term can also refer either to the physical streets and buildings of the city or to the collection of people who dwell there and can be used in a general sense to mean urban rather than rural territory . National censuses use a variety of definitions – invoking factors such as population , population density , number of dwellings , economic function, and infrastructure – to classify populations as urban. Typical working definitions for small-city populations start at around 100,000 people. Common population definitions for an urban area (city or town) range between 1,500 and 50,000 people, with most U.S. states using

1210-461: A central point. This form could evolve from successive growth over a long time, with concentric traces of town walls and citadels marking older city boundaries. In more recent history, such forms were supplemented by ring roads moving traffic around the outskirts of a town. Dutch cities such as Amsterdam and Haarlem are structured as a central square surrounded by concentric canals marking every expansion. In cities such as Moscow , this pattern

1452-539: A combination of these. Societies that live in cities are often called civilizations . The degree of urbanization is a modern metric to help define what comprises a city: "a population of at least 50,000 inhabitants in contiguous dense grid cells (>1,500 inhabitants per square kilometer)". This metric was "devised over years by the European Commission , OECD , World Bank and others, and endorsed in March [2021] by

1573-604: A continuous urban landscape called urban agglomeration , conurbation , or megalopolis (exemplified by the BosWash corridor of the Northeastern United States .) The emergence of cities from proto-urban settlements , such as Çatalhöyük , is a non-linear development that demonstrates the varied experiences of early urbanization . The cities of Jericho , Aleppo , Byblos , Faiyum , Yerevan , Athens , Matera , Damascus , and Argos are among those laying claim to

1694-430: A distinctive elite social class, but it should indeed be considered a city based on a functional redefinition of urban development. In particular, Jenné-Jeno featured settlement mounds arranged according to a horizontal, rather than vertical, power hierarchy, and served as a center of specialized production and exhibited functional interdependence with the surrounding hinterland. More recently, scholars have concluded that

1815-431: A female householder with no spouse present. 18.4% of the households had individuals under the age of 18 living in them, and 20.1% had individuals over age 65 living in them. The average household size was 2.22 people and the average family size was 2.78 people. The median age was 25.9; 12.2% of the population was under age 18, and 12.3% was age 65 or older. The percentage of city residents age 25 years or older with at least

The urban-type settlement extends far beyond the traditional boundaries of the city proper in a form of development sometimes described critically as urban sprawl . Decentralization and dispersal of city functions (commercial, industrial, residential, cultural, political) has transformed the very meaning of

2057-507: A key role in both the economy and government. Late antique cities in the East were also undergoing intense transformations, with increased political participation of the crowds and demographical fluctuations. Christian communities and their doctrinal differences increasingly shaped the urban fabric. The locus of power shifted to Constantinople and to the ascendant Islamic civilization with its major cities Baghdad , Cairo , and Córdoba . From

2178-497: A locus for left-wing activism and anti-Vietnam War movement , as well as the student movement. The first major meetings of the national left-wing campus group Students for a Democratic Society took place in Ann Arbor in 1960; in 1965, the city was home to the first U.S. teach-in against the Vietnam War . During the ensuing 15 years, many countercultural and New Left enterprises sprang up and developed large constituencies within

2299-520: A minimum between 1,500 and 5,000 inhabitants. Some jurisdictions set no such minima. In the United Kingdom , city status is awarded by the Crown and then remains permanent. (Historically, the qualifying factor was the presence of a cathedral , resulting in some very small cities such as Wells , with a population of 12,000 as of 2018 , and St Davids , with a population of 1,841 as of 2011 .) According to

2420-419: A north–south railway connecting Ann Arbor to Toledo and other markets to the south was established in 1878. Throughout the 1840s and the 1850s settlers continued to come to Ann Arbor.

2904-688: A privileged elite among towns having won self-governance from their local lord or having been granted self-governance by the emperor and being placed under his immediate protection. By 1480, these cities, as far as still part of the empire, became part of the Imperial Estates governing the empire with the emperor through the Imperial Diet . By the 13th and 14th centuries, some cities become powerful states, taking surrounding areas under their control or establishing extensive maritime empires. In Italy, medieval communes developed into city-states including

3025-495: A rule cannot produce their own food and therefore must develop some relationship with a hinterland that sustains them. Only in special cases such as mining towns which play a vital role in long-distance trade, are cities disconnected from the countryside which feeds them. Thus, centrality within a productive region influences siting, as economic forces would, in theory, favor the creation of marketplaces in optimal mutually reachable locations. The vast majority of cities have

3146-549: A super-wealthy elite living in gated communities and large masses of people living in substandard housing with inadequate infrastructure and otherwise poor conditions. Cities around the world have expanded physically as they grow in population, with increases in their surface extent, with the creation of high-rise buildings for residential and commercial use, and with development underground. Urbanization can create rapid demand for water resources management , as formerly good sources of freshwater become overused and polluted, and

3267-423: A temple. A minority viewpoint considers that cities may have arisen without agriculture, due to alternative means of subsistence (fishing), to use as communal seasonal shelters, to their value as bases for defensive and offensive military organization, or to their inherent economic function. Cities played a crucial role in the establishment of political power over an area, and ancient leaders such as Alexander

However, Ann Arbor's property crime rate, at 1726.0 per 100,000 people, is higher than Michigan's property crime rate of 1536.8 per 100,000 people and lower than the U.S. national property crime rate of 1954.4 per 100,000 people. The University of Michigan shapes Ann Arbor's economy significantly. It employs about 30,000 workers which includes about 12,000 in

3630-595: A vociferous local debate has hinged on how and whether to accommodate and guide development within city limits. Ann Arbor consistently ranks in the "top places to live" lists published by various mainstream media outlets every year. In 2016, the city changed mayoral terms from two years to four. Until 2017, City Council held annual elections in which half of the seats (one from each ward) were elected to 2-year terms. These elections were staggered, with each ward having one of its seats up for election in odd years and its other seat up for election in even years. Beginning in 2018

3751-567: A workers' town associated with the pyramid of Senusret II , and the religious city Amarna built by Akhenaten and abandoned. These sites appear planned in a highly regimented and stratified fashion, with a minimalistic grid of rooms for the workers and increasingly more elaborate housing available for higher classes. In Mesopotamia, the civilization of Sumer , followed by Assyria and Babylon , gave rise to numerous cities, governed by kings and fostered multiple languages written in cuneiform .

The word city and the related civilization come from the Latin root civitas , originally meaning 'citizenship' or 'community member' and eventually coming to correspond with urbs , meaning 'city' in a more physical sense. The Roman civitas was closely linked with the Greek polis —another common root appearing in English words such as metropolis . In toponymic terminology, names of individual cities and towns are called astionyms (from Ancient Greek ἄστυ 'city or town' and ὄνομα 'name').

7260-666: The world population now lives in cities, which has had profound consequences for global sustainability . Present-day cities usually form the core of larger metropolitan areas and urban areas —creating numerous commuters traveling toward city centres for employment, entertainment, and education. However, in a world of intensifying globalization , all cities are to varying degrees also connected globally beyond these regions. This increased influence means that cities also have significant influences on global issues , such as sustainable development , climate change , and global health . Because of these major influences on global issues,

7381-535: The " Global North " remain more urbanized than the less developed countries of the " Global South "—but the difference continues to shrink because urbanization is happening faster in the latter group.

7502-539: The "functional definition", a city is not distinguished by size alone, but also by the role it plays within a larger political context. Cities serve as administrative, commercial, religious, and cultural hubs for their larger surrounding areas. The presence of a literate elite is often associated with cities because of the cultural diversities present in a city. A typical city has professional administrators , regulations, and some form of taxation (food and other necessities or means to trade for them) to support
