Acity is ahuman 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 anddensely populated place with administratively defined boundaries whose members work primarily on non-agricultural tasks. Cities generally have extensive systems forhousing,transportation,sanitation,utilities,land use,production of goods, andcommunication. Their density facilitates interaction between people,government organizations, andbusinesses, sometimes benefiting different parties in the process, such as improving the efficiency of goods and service distribution.
Historically, city dwellers have been a small proportion of humanity overall, but following two centuries of unprecedented and rapidurbanization, more than half of theworld population now lives in cities, which has had profound consequences forglobal sustainability. Present-day cities usually form the core of largermetropolitan areas andurban areas—creating numerouscommuters traveling towardcity centres for employment, entertainment, and education. However, in a world of intensifyingglobalization, all cities are to varying degrees also connected globally beyond these regions. This increased influence means that cities also have significant influences onglobal issues, such assustainable development,climate change, andglobal health. Because of these major influences on global issues, theinternational community has prioritized investment insustainable cities throughSustainable Development Goal 11. Due to the efficiency of transportation and the smallerland consumption,dense cities hold the potential to have a smallerecological footprint per inhabitant than more sparsely populated areas. Therefore,compact cities are often referred to as a crucial element in fighting climate change. However, this concentration can also have some significant harmful effects, such as formingurban heat islands, concentratingpollution, and stressing water supplies and other resources.
