A city is a human settlement of a substantial size. The term "city" has different meanings around the world and in some places the settlement can be very small. Even where the term is limited to larger settlements, there is no universally agreed definition of the lower boundary for their size. In a narrower sense, a city can be defined as a permanent and densely populated place with administratively defined boundaries whose members work primarily on non-agricultural tasks. Cities generally have extensive systems for housing , transportation , sanitation , utilities , land use , production of goods , and communication . Their density facilitates interaction between people, government organizations , and businesses , sometimes benefiting different parties in the process, such as improving the efficiency of goods and service distribution.

With the outbreak of the Croatian War of Independence in 1991, Sisak remained in Government hands while the territory to the south was controlled by rebelling Serbs . During the war, the Serb forces often shelled the city, causing dozens of civilian casualties and extensive damage to the city's industry. According to Amnesty International , Serb civilians in Sisak and surrounding areas were subjected to abductions, killings, assault and threats with at least 33 killed between 1991 and 1992, while local human rights activists in Croatia claim that over 100 Serb residents of
225-573: 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
300-665: 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
375-461: 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
450-539: 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

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

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

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
750-507: 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

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

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

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'). Urban geography deals both with cities in their larger context and with their internal structure. Cities are estimated to cover about 3% of
