A town is a type of a human settlement. Towns are generally larger than villages and smaller than cities, though the criteria to distinguish between them vary considerably in different parts of the world.
A metropolitan area or metro is a region consisting of a densely populated urban agglomeration and its surrounding territories which share industries, commercial areas, transport network, infrastructures and housing. A metropolitan area usually comprises multiple principal cities, jurisdictions and municipalities: neighborhoods, townships, boroughs, cities, towns, exurbs, suburbs, counties, districts and even states and nations in areas like the eurodistricts. As social, economic and political institutions have changed, metropolitan areas have become key economic and political regions.
A census tract, census area, census district or meshblock is a geographic region defined for the purpose of taking a census. Sometimes these coincide with the limits of cities, towns or other administrative areas and several tracts commonly exist within a county. In unincorporated areas of the United States these are often arbitrary, except for coinciding with political lines.
A census-designated place (CDP) is a concentration of population defined by the United States Census Bureau for statistical purposes only.
A hamlet is a human settlement that is smaller than a town or village. This is often simply an informal description of a smaller settlement or possibly a subdivision or satellite entity to a larger settlement. Sometimes a hamlet is defined for official or administrative purposes.
A geocode is a code that represents a geographic entity. It is a unique identifier of the entity, to distinguish it from others in a finite set of geographic entities. In general the geocode is a human-readable and short identifier.
An urban area is a human settlement with a high population density and an infrastructure of built environment. This is the core of a metropolitan statistical area in the United States, if it contains a population of more than 50,000.
An urban area or tätort in Sweden has a minimum of 200 inhabitants and may be a city, town or larger village. It is a purely statistical concept, not defined by any municipal or county boundaries. Larger urban areas synonymous with cities or towns for statistical purposes have a minimum of 10,000 inhabitants. The same statistical definition is also used for urban areas in the other Nordic countries.
Greater Glasgow is an urban settlement in Scotland consisting of all localities which are physically attached to the city of Glasgow, forming with it a single contiguous urban area. It does not relate to municipal government boundaries, and its territorial extent is defined by National Records of Scotland, which determines settlements in Scotland for census and statistical purposes. Greater Glasgow had a population of 1,199,629 at the time of the 2001 UK Census making it the largest urban area in Scotland and the fifth-largest in the United Kingdom. However, the population estimate for the Greater Glasgow 'settlement' in mid-2016 was 985,290—the reduced figure explained by the removal of the Motherwell & Wishaw (124,790), Coatbridge & Airdrie (91,020), and Hamilton (83,730) settlement areas east of the city due to small gaps between the populated postcodes. The 'new towns' of Cumbernauld and East Kilbride (75,120) were never included in these figures despite their close ties to Glasgow due to having a clear geographical separation from the city. In the 2020 figures, the Greater Glasgow population had risen to just over 1 million.
Spatial analysis is any of the formal techniques which studies entities using their topological, geometric, or geographic properties. Spatial analysis includes a variety of techniques using different analytic approaches, especially spatial statistics. It may be applied in fields as diverse as astronomy, with its studies of the placement of galaxies in the cosmos, or to chip fabrication engineering, with its use of "place and route" algorithms to build complex wiring structures. In a more restricted sense, spatial analysis is geospatial analysis, the technique applied to structures at the human scale, most notably in the analysis of geographic data. It may also be applied to genomics, as in transcriptomics data.
The Australian Bureau of Statistics (ABS) is an Australian Government agency that collects and analyses statistics on economic, population, environmental, and social issues to advise the Australian Government.
The United States Census Bureau defines a place as a concentration of population which has a name, is locally recognized, and is not part of any other place. A place typically has a residential nucleus and a closely spaced street pattern, and it frequently includes commercial property and other urban land uses. A place may be an incorporated place or it may be a census-designated place (CDP). Incorporated places are defined by the laws of the states in which they are contained. The Census Bureau delineates CDPs. A small settlement in the open countryside or the densely settled fringe of a large city may not be a place as defined by the Census Bureau. As of the 1990 census, 26% of the people in the United States lived outside of places.

In Ukraine, the term "populated place" refers to a structured component of the human settlement system, representing a stationary community within a territorially cohesive and compact area characterized by a significant concentration of population. Its defining attribute is the continuous presence of human inhabitants. Populated places in Ukraine are classified into two primary categories: urban and rural. Urban populated places are cities, whereas rural areas include villages and rural settlements. According to data from the 2001 Ukrainian Census, there are 1,344 urban and 28,621 rural populated places in Ukraine.
In urban planning, a historic core city or central city is the municipality with the largest 1940 population in the present metropolitan 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.
