Abandoned City San Zhi, Taiwan

A Review of Scotland's Cities led to the Fair City of Perth, Scotland, losing city status. By both legal and traditional definition, a town may be of any size, but must contain a market place. A village must contain a church. A small village without a church is called a hamlet.
The UK's five largest cities are generally considered to be London, Birmingham, Leeds, Manchester and Glasgow, but this is based on the population of the conurbation as a whole. In terms of formal city boundaries, the largest include Bristol, Cardiff, Edinburgh, Liverpool and Sheffield.
• United States
In the United States of America, the classification of population centers is a matter of state law; consequently, the definition of a city varies widely from state to state. In some states, a city may be run by an elected mayor and city council, while a town is governed by the people, a select board (or board of trustees), or open town meeting. There are some very large municipalities which label themselves as towns (such as Hempstead, New York, with a population of 755,785 in 2004 or Cary, North Carolina with a population of 112,414 in 2006 ) and some very small cities (such as Woodland Mills, Tennessee, with a population of 296 in 2000), and the line between town and city, if it exists at all, varies from state to state. The lack of a clear-cut definition of a city in the United States can lead to some counter-intuitive labeling; for example, before it was dissolved in 2002 Maza, North Dakota, with only 5 inhabitants, was a city as by North Dakota law any incorporated location is deemed a city regardless of size. California has both towns and cities but the terms "town" and "city" are considered synonymous. The nation's top five largest cities are New York City, Los Angeles, Chicago, Houston, and Philadelphia.
